Description
Elektrisk ledende glasslignende material. Electrically conductive glass-like material.
Oppfinnelsen vedrører glasslignende materialer som har elektroneledningsevne, og en fremgangsmåte til fremstilling av disse materialer. The invention relates to glass-like materials that have electron conductivity, and a method for producing these materials.
Det er kjent sintrede oksydiske materialer, som har elektroneledningsevne da There are known sintered oxide materials, which have electron conductivity then
det i materialet minst er til stede et metall-ion i mer enn en verdighetsform. Denne materialtype har begrensede anvendelses-muligheter. Da disse materialer fremstilles ved sintring og følgelig i de gunstigste tilfelle bare fås et tilnærmet helt tett pro-dukt, har ingen optimale fysikalske egenskaper. Også formgivningen av sintrede le-gemer har visse begrensninger, dessuten krever sintringen vanligvis en høy temperatur. Denne legemstype er følgelig hver-ken spesiell interessant i teknologisk hen-seende eller med hensyn til de ønskede fysikalske egenskapers reproduserbarhet. Av de to nevnte grunner ville det være å foretrekke elektrisk, ledende glasslignende materialer. Imidlertid er det tidligere ikke be-skrevet noe elektrisk ledende glass med for praktisk anvendbarhet tilstrekkelig høy ledningsevne. that in the material at least one metal ion is present in more than one form of dignity. This type of material has limited application possibilities. Since these materials are produced by sintering and consequently in the most favorable cases only an almost completely dense product is obtained, none have optimal physical properties. The shaping of sintered bodies also has certain limitations, and the sintering usually requires a high temperature. This body type is consequently neither particularly interesting in technological terms nor with regard to the reproducibility of the desired physical properties. For the two reasons mentioned, electrically conductive glass-like materials would be preferable. However, no electrically conductive glass with sufficiently high conductivity for practical use has previously been described.
Det er kjent et glass som består av et titanoksydholdig alkalisilikatglass, hvor titan-ionene er tilstede i forskjellige ver-digheter, og i en samlet mengde på 14—45 vektsprosent, beregnet etter oksydet. I gunstigste tilfelle lar det seg med dette glass oppnå en spesifikk motstand, målt ved 50° C, på ikke mindre enn 20 000 ohm cm. A glass is known which consists of an alkali silicate glass containing titanium oxide, where the titanium ions are present in different amounts, and in a total amount of 14-45% by weight, calculated according to the oxide. In the most favorable case, it is possible with this glass to achieve a specific resistance, measured at 50° C, of no less than 20,000 ohm cm.
Oppfinnelsen vedrører et elektrisk le- The invention relates to an electric le-
dende glass med en spesifikk motstand (o), dend glass with a specific resistance (o),
målt ved 50° C på bare 10—1000 ohm cm. measured at 50° C of only 10—1000 ohm cm.
Oppfinnelsen vedrører altså et elektrisk ledende glasslignende material og krystalliserte produkter som på kjent måte er dannet av dette material, og materialet er karakterisert ved at det til minst 90 vektsprosent består av SiO„ og/eller B.,0, AL>0.,, Na,0, Fe20., og FeO, i følgende mengder i vektsprosent hvor den samlede mengde av Fe.,0., og FeO er beregnet som Fe..O,: idet det molekylære forhold mellom Fe„0;! og FeO ligger mellom 1:2 og 4:1, mens resten av materialet på maksimalt 10 vekt-prosent kan bestå av: The invention therefore relates to an electrically conductive glass-like material and crystallized products which are formed in a known manner from this material, and the material is characterized in that it consists of at least 90% by weight of SiO„ and/or B.,0, AL>0.,, Na,0, Fe20., and FeO, in the following amounts in percentage by weight where the total amount of Fe.,0., and FeO is calculated as Fe..O,: the molecular ratio between Fe„0;! and FeO is between 1:2 and 4:1, while the rest of the material at a maximum of 10 percent by weight can consist of:
For å oppnå glass av denne sammensetning smeltes de angjeldende oksyder eller forbindelser som ved oppvarmning omdannes i disse oksyder i en svakt reduserende til svakt oksyderende atmosfære på den i glassteknikken vanlige måte, ved en temperatur mellom 1000° og 1650° C. In order to obtain glass of this composition, the relevant oxides or compounds which, when heated, are converted into these oxides are melted in a weakly reducing to weakly oxidizing atmosphere in the usual way in glass technology, at a temperature between 1000° and 1650°C.
En svakt" reduserende atmosfære oppnås ved at utgangsstoffene smeltes i en flamme som mates med en blanding av hy-drogen og oksygen med et overskudd på 10 volumprosent hydrogen med hensyn til den støkiometriske volummengde knallgass. En svakt oksyderende atmosfære oppnås med en flamme som drives med lysgass og et lite overskudd av oksygen, f. eks. i en mengde på 10 volumprosent. A weak "reducing atmosphere" is obtained by melting the starting materials in a flame which is fed with a mixture of hydrogen and oxygen with an excess of 10 percent by volume of hydrogen with respect to the stoichiometric volume amount of explosive gas. A weakly oxidizing atmosphere is obtained with a flame which is fueled with light gas and a small excess of oxygen, for example in an amount of 10 percent by volume.
Vesentlig for den høye elektriske ledningsevne av glasstypen ifølge oppfinnelsen er nærvær av ferri- ved siden av ferro-ioner i et forhold som i avhengighet av den ovenfor nevnte atmosfære type, hvori glasset smeltes, ligger mellom 1 : 1 og 8 : 1. For fremstilling av glasset kan jern oksydet settes til blandingen i form av magnetitt (Fe.,04), hvis ønskes sammen med en fer-roforbindelse, f. eks. ferro-oksalat. Ved til-setning som adskilte ferri- og ferroforbin-delser, f. eks. i form av Fe2Os og ferro-oksalat, finnes en avvikelse som ligger in-nenfor feilgrensen. Anvendes FeaO,, som ut-gangsstoff så foregår det en reaksjon av Fe30., med de øvrige glassblandingsbe-standdeler. Ved sammenligning av de to fremgangsmåter av jernoksydtilsetningen ved hjelp av en grafisk fremstilling av log q, f. eks. målt ved 150° C, av et antall sammensetninger hvor jernoksyd er tilsatt til blandingen i form av Fe30„ og en slik av log q' av samme sammensetning hvori dette oksyd er tilsatt i form av en blanding av Fe^O,, og ferrooksalat, fremkommer det et antall punkter som ved korrektur av log o-verdiene gir et rettlinjet forhold log q' = 0,958 log q —0,005, ved korrektur av log o' finnes da et rettlinjet forhold log q' = 0,45 log p +1,41. Herav fremgår altså den kjemiske reaksjon mellom jernoksyd og de øvrige bestanddeler av blandingen, og det viser seg dessuten at tilsetningen av jernoksyd i form av adskilte ferri- og ferro-forbindelser er å foretrekke. Essential for the high electrical conductivity of the glass type according to the invention is the presence of ferric next to ferrous ions in a ratio which, depending on the type of atmosphere mentioned above, in which the glass is melted, is between 1 : 1 and 8 : 1. For production of the glass, the iron oxide can be added to the mixture in the form of magnetite (Fe.,04), if desired together with a ferro compound, e.g. ferrous oxalate. By adding separate ferric and ferrous compounds, e.g. in the form of Fe2Os and ferrous oxalate, there is a deviation that lies within the margin of error. If FeaO,, is used as a starting material, a reaction of Fe30,, with the other glass mixture constituents takes place. When comparing the two methods of the iron oxide addition using a graphical representation of log q, e.g. measured at 150° C, of a number of compositions where iron oxide is added to the mixture in the form of Fe30„ and one of log q' of the same composition in which this oxide is added in the form of a mixture of Fe^O,, and ferrous oxalate, a number of points appear which, when correcting the log o values, gives a straight-line relationship log q' = 0.958 log q -0.005, when correcting log o' there is then a straight-line relationship log q' = 0.45 log p +1, 41. This shows the chemical reaction between iron oxide and the other components of the mixture, and it also turns out that the addition of iron oxide in the form of separate ferric and ferrous compounds is preferable.
Det skal dessuten bemerkes at smelte-atmosfæren med hensyn til de oppnådde verdier av spesifikk motstand er mindre kritisk ved glasstyper som ikke inneholder tre- eller toverdig koboltoksyd. Forøvrig vil det ved smelter i en svakt reduserende atmosfære finnes log g-verdier som er om-trent en enhet lavere enn ved smeiten i en svakt oksyderende atmosfære. Ved tilsetningen av kobolt-ioner kan glasstypens ledningsevne påvirkes. It should also be noted that the melting atmosphere with regard to the obtained values of specific resistance is less critical for glass types that do not contain trivalent or divalent cobalt oxide. Incidentally, when smelting in a weakly reducing atmosphere, there will be log g values that are approximately one unit lower than when smelting in a weakly oxidizing atmosphere. The conductivity of the glass type can be affected by the addition of cobalt ions.
Glasstypene ifølge oppfinnelsen lar seg anvende som ledende sammensmeltninger, glasselektroder, som varmeelementer, f. eks. brødristere, som kolber for geigerteller osv. De er ugjennomsiktige og har en dyp sort farve. The types of glass according to the invention can be used as conductive fusions, glass electrodes, as heating elements, e.g. toasters, like flasks for Geiger counters, etc. They are opaque and have a deep black color.
De kan på kjent måte ved oppvarm - ning bringes til krystallisering, idet en for-anderlig del av glasset avhengig av den termiske behandling utskiller små krystal-ler i findispergert form. Dette utøver knapt noen innvirkning på glassets ledningsevne, men de mekaniske egenskaper, spesielt hårdhet og bruddstyrke forbedres derved i betraktelig grad. They can be brought to crystallization in a known manner by heating, as a variable part of the glass, depending on the thermal treatment, secretes small crystals in finely dispersed form. This has hardly any effect on the glass's conductivity, but the mechanical properties, especially hardness and breaking strength, are thereby improved to a considerable extent.
For nærmere å forklare oppfinnelsen skal det i det følgende angis noen spesifike eksempler. Tabell I inneholder et stort antall sammensetninger ifølge oppfinnelsen, såvel som den Briggske logaritime av den med disse sammensetninger oppnådde verdier for spesifikk motstand g i Ohm cm, målt ved 100° C og 50° C. Angivelsen «ox» og «red» betegner den anvendte smelte-atmosfære, nemlig oksyderende resp. reduserende slik det er angitt ovenfor. Endelig er aktiviseringsenergien E a angitt i eV, beregnet fra verdien av B fra ligningen log q A + ^ idet verdien av B igjen er fremkommet ved spesifike motstandsmå-linger ved 50° C, 100° C, 150° C, 200° C 300° C og 500° C. Verdien av E |A i eV fremkommer fra multiplikasjon av B med faktor 0,198 x 10-3. In order to explain the invention in more detail, some specific examples will be given in the following. Table I contains a large number of compositions according to the invention, as well as the Briggs logarithm of the values for specific resistance g in Ohm cm obtained with these compositions, measured at 100° C and 50° C. The indications "ox" and "red" denote the used melting atmosphere, namely oxidizing or reducing as indicated above. Finally, the activation energy E a is stated in eV, calculated from the value of B from the equation log q A + ^, the value of B having again been obtained by specific resistance measurements at 50° C, 100° C, 150° C, 200° C 300 ° C and 500° C. The value of E |A in eV results from multiplying B by the factor 0.198 x 10-3.
Tabell II gir endelig noen sammensetninger som riktignok inneholder bestand-delene ifølge oppfinnelsen, imidlertid i mengder som ligger utenfor de angitte grenser. Den spesifike motstand av legemene med disse sammensetninger er betraktelig høyere enn ved legemene frem-stillet ifølge oppfinnelsen. Table II finally gives some compositions which do indeed contain the constituent parts according to the invention, however in quantities that lie outside the specified limits. The specific resistance of the bodies with these compositions is considerably higher than with the bodies produced according to the invention.
