Definitions
- the present invention is directed to non-evaporable getter alloys capable of sorbing different gases but particularly useful for the sorption of hydrogen.
- NEG materials non-evaporable getter materials
- materials being capable of chemically fixing molecules of gases such as water, oxygen, hydrogen, carbon oxides and, in some cases, nitrogen, hi order to accomplish their function
- NEGs generally require an initial treatment of thermal activation at temperatures that can vary between about
- NEGs are generally metals of the III, IV and V transition groups or alloys illy other trans most used getter materials are titanium- and, partici
- NEG materials show a sorption behavior with respect to hydrogen different from that towards other gases. While for most gases the chemical sorption by these alloys is irreversible, the sorption of hydrogen by NEGs is an equilibrium process reversible as a function of the temperature: hydrogen is efficiently sorbed at relatively low temperatures (under 200-400 °C, according to the chemical composition of the material), but it is released at higher temperatures.
- the equilibrium features of these materials in sorbing hydrogen are generally represented graphically by means of curves giving, at different temperatures, the equilibrium pressure of hydrogen over the NEG material as a function of the hydrogen concentration in the same material.
- Advantageous features for a NEG material are a low activation temperature and, when hydrogen sorption is considered, a low hydrogen equilibrium pressure in the whole range of temperatures at which the material is to be used.
- NEG materials especially suitable for hydrogen sorption are pure yttrium and an alloy disclosed in US pat. No. 3,203,901 and containing, by weight, 84% zirconium and 16% aluminum; both these materials require however relatively high temperatures for their activation, in the range of about 700-900 °C (depending on the degree of activation desired).
- Another material widely employed for hydrogen sorption is an alloy of approximate composition, by weight, 80% zirconium, 15% cobalt and 5% mischmetal (a commercial mixture of lanthanum and/or cerium and Rare Earths), disclosed in US pat. No. 5,961,750; this material has the drawback of a relatively high hydrogen equilibrium pressure at temperatures in excess of about 500 °C.
- Object of the present invention is to provide non-evaporable getter alloys that can sorb a wide variety of gasses, and with specially good hydrogen sorption properties.
- non- evaporable getter alloys comprising, by weight, from 60% to 85% yttrium, from 5% to 30% manganese and from 5% to 20% aluminum.
- Figure 1 shows a ternary diagram representing the range of possible compositions of the NEG alloys according to the invention
- Figures 2a-2d show some possible embodiments of non-evaporable getter devices made by using the alloys of the invention
- Figures 3 to 6 represent graphs showing the gas sorption features of an alloy of the invention and of some getter materials of the prior art.
- the alloys of the invention are those falling within the polygon highlighted in the ternary diagram of weight percentage compositions of Figure 1.
- the alloys of the invention can be prepared by melting in furnace, from pieces or powders of the component metals, taken in the mutual ratios corresponding to the desired final composition.
- Preferred are the techniques of arc melting under inert gas, e.g. with a pressure of 3 x 10 4 Pascal (Pa) of argon; or in an induction furnace, under vacuum or inert gas. It is however possible to adopt other techniques which are common in the metallurgical field for preparing alloys. Melting requires temperatures higher than 1000 °C.
- the alloys in powder form, with particle size generally lower than 250 micrometers ( ⁇ m) and preferably comprised between 40 and 125 ⁇ m. Greater particle sizes result in an excessive reduction of the specific surface (surface area per weight unit) of the material, with consequent reduction of the gas sorption properties, in particular the sorption speed at low temperatures; although their use is possible and required in some applications, particles of size less than 40 ⁇ m may give rise to problems in the manufacturing steps of getter devices, especially due to their flammability/explosivity when exposed to air.
- the shapes in which the getter devices can be prepared by using the alloys of the invention are the most various, comprising pills formed of the getter alloy powders alone, or of these on a metallic support. In both cases the powders can be compacted either by compression or sintering, or both. The pills made only of compressed powders may be used for example in the thermal insulation of thermoses.
- steel, nickel or nickel-based alloys are generally used as supporting material.
- the support can merely be in form of a strip on the surface of which the alloy powders are caused to adhere by either cold rolling or sintering after deposition by means of various techniques.
- the support can also be formed as an actual container, having the most various shapes, in which the powders are generally introduced by compression or even without compression in some devices in which the container has the capability to retain powders, either thanks to its shape or because provided with a porous septum permeable to gas flow.
- figure 2a shows a pill 20 made of compressed powders only of NEG alloy
- Figure 2b shows a NEG device 30 formed of a metallic strip 31 on which powders 32 of NEG alloy are present
- figure 2c shows in cross-section a NEG device 40 formed of a metallic container 41 with an upper opening 42 having at the inside thereof powders 43 of NEG alloy
- figure 2d shows in cross-section a NEG device 50 consisting of a metallic container 51 having inside powders 52 of NEG d by a porous shapes and configurations of devices using the ge possible.
- the NEG alloys of the invention can be activated by means of treatments of a few tens of minutes at 500 °C or at about 300 0 C during one or two hours, which are softer conditions than those typically required by pure yttrium or zirconium- aluminum alloys (these latter needing temperatures of about 800-900 0 C); furthermore, they show good properties of hydrogen sorption at temperatures lower than those required by using yttrium or compositions of the prior art containing this element as the main component; at the same time, the alloys of the invention show better properties as to sorption of gases different from hydrogen compared to the previously described getter alloys of the prior art (generally containing zirconium as the main component).
- This example describes the preparation of an alloy of the invention.
- An alloy of composition Y 75% - Mn 15% - Al 10%, corresponding to point a in the ternary diagram of figure 1, is produced starting from powders of the component elements weighed in the desired ratio. The powders are mixed and poured into a water cooled copper crucible of an arc furnace under an * atmosphere of 3 x 10 4 Pa of argon (so-called "cold-earth” technique). The temperature reached by the mixture during melting is of about 2000 °C, temperature that is maintained during about 5 minutes; the melt is then allowed to cool down to room temperature, obtaining an ingot of the alloy. Since the preparation takes place under conditions of high thermal gradient, in order to enhance the alloy homogeneity the melting is repeated four times. The ingot obtained by cooling and the resuli retrieving the fraction with particle size comprised
- each of the pills referred to as “sample 1" in the following, are obtained compressing 120 mg of powder under a pressure of 2000 kg/cm 2 .
- a hydrogen sorption test is carried out on a pill of sample 1 and on a pill of weight 120 mg obtained by compressing powders of pure yttrium. The pills are activated at 500 °C for 30 minutes. The sorption tests are carried out according to the procedure described in the ASTM F 798-82 standard with a test temperature of
- test chamber is fed with a variable flow of hydrogen, regulated by means of a feed-back system, in order to have a constant pressure of H 2 over the pill during the test.
- the hydrogen equilibrium pressure properties of a sample of an alloy of the invention are measured the hydrogen equilibrium pressure properties of a sample of an alloy of the invention.
- the measurement system is formed as a glass bulb, connected to a pumping apparatus through a liquid nitrogen trap which helps to keep a low background pressure during the test; the sample is heated from the outside of the bulb by radio-frequencies by means of an induction coil.
- the system is evacuated until a residual pressure of 1 x 10 "4 Pa is reached.
- Under pumping the sample is activated by heating with radio-frequency at 700 0 C for an hour.
- the sample is brought to the temperature of 600 °C and the bulb is isolated asured quantity the bulb and the pressure variations are measun manometer; the pressure value at which the system stabilizes provides the equilibrium pressure under those conditions.
- Such a procedure is repeated several times, introducing each time a different quantity of hydrogen into the system. From the measurement of the equilibrium pressures, being known the system volume and the weight of the sample, the concentration of hydrogen sorbed by the
- segment 3 represents the properties of an alloy of composition Zr 80.8% - Co 14.2% - mischmetal 5.0% (known from US patent No. 5,961,750).
- Segments 2 and 3 are portions of lines obtained by averaging the data resulting from a number of experimental tests carried out in the past with said known alloys in the same conditions as described above for sample 1.
- the graph of figure 3 confirms that the alloys of the invention have better hydrogen sorption properties than those of a sample of pure yttrium activated under the same conditions.
