PROCESS OF TREATING ALKALINE SILICATES, 80C.
SPECIFICATION forming part of Letters Patent No. 317,387, dated May 5, 1885.
Application filed August 13, l884. (No specimens.)
.To all whom it may concern.-
Be it known that we, CHARLES S. LOCKWOOD, a citizen of the United States, and a resident of Albany, in the county of Albany and State of New-York, and JoHNW. HYATT, a citizen of the United States, and a resident of Newark, Essex county, New Jersey, have invented certain new and useful Improved Processes of Treating Alkaline Silicates and the Resultant Composition and Products, of which the following is a specification.
The invention relates to an improved process of treating alkaline silicates and to the resultant composition and products, and has for its object the production of a material which may be utilized in the manufacture of articles usually made of ivory and its substitutes.
Alkaline silicates combined with other substances have heretofore been pressed in heated molds, and reference is made in this connection to Letters Patent of the United States No. 201, 348,grauted to John W. Hyatt and Charles M. Hyatt on the 19th day of March, 1878.
The process herein described is based upon the discoverythat alkaline silicates,whenproperly desiccated and comminuted, may be successfully molded to form articles of exceptional durability and value. The silicate, with or without suitable oxides or other inert materials, is subjected to heat and pressure when it is in a particular condition, as hereinafter de-. scribed, wherebya new result is produced.
In practice we make use of any alkaline silicac,selecting,bypreference,onehav1ugamini- 3 5 mum percentage of alkali. The silicate being in solution, we add to it a sufficient quantity of water to enable us to effect a thorough filtra ion and reduce the filtered solution to such an extent that at a temperature of 60 it has 0 a specific gravity of about 26 Baum. 701' I the solution, in the condition just stated, we take, gay,f eight pouinds, andhadd to igi say,two poun s o zinc oxi e or ot er meta ic oxide or inert suEEnce, many kinds of which may be used, according to the quality of material desired,) and mix the two ingredients together as thoroughly as possible. We then place the mixture preferably on a water bath and eva es have WA until the aqueous particl so a r ecu removed as to permit the material to be 'comminuted, which may be effected by grinding or otherwise; or the removal of the aqueous particles to the proper extent and the comminution of the material may be accomplished in other ways. Before the comminution of the material is attempted it will be allowed to become cool, when its reduction to a powder may be readily efi'ected by means of a mill of appropriate construction. The material will be nd to an impalpable powder, and by pre1%"s'iftcd so as to insure the production of a powder composed as far as practicable of particles of relatively equal size. After the powder has been sifted we havebecn accustomed to put it in an evaporating-pan 6 5 and stir it continuously until it is in a condition in which it will not adhere to the surface of the die under the degree of heat and pressure required to weld it, as hereinafter statedsay, a temperature of 300 Fahrenheit and a 7 pressure of eight thousand pounds to the square inch-by which test the operator may ascertain whether the proper degree of desiccation has been reached. If the powder does not adhere to the die, it may be concluded that it is 7 5 in a proper condition.
The next step in the process consists in subjecting the powder formed as hereinbefore described to ressure in heated dies whereby any desired article may e o he dies employed are of usual construction. They will be heated to a temperature of,fsay, about 250 to 350 Fahrenheit,or thereabout, and the material will be subjected to apressurc of about, say, eight thousand pounds to the square inch, more or..less, according to the character of the article, the heat and pressure being continued until the contents of the moldhave been completely welded.
After the article is formed it may be polished in any convenient way,whenit may be placed in abath preferably of chloriwgmmoniu m consis mg 0 say, a on no par s o wa er and one part of chloride of ammonium, in which it will be permitted to remain from,say, 5 ten to fifteen hours, or until a test will show no further alkaline reaction. We prefer to use a bath of chloride of ammonium, but other baths may be used with satisfactory results,';. theobject of the treatment ipthe'hath being 3.
to correct the tendency of the material to ating a solution of the silicate and, if preferred,
tract moisture'and to eflioresce. 7 After the article is taken from the bath it is thoroughly washed,when it will be ready for use.
We do not wish tobe understood as confining ourselves to any particular oxide or inert material. 1
It is important that it be borne in mind thatunless the material is reduced to the proper degree of dryness without being completely dehydrated the result will not be satisfactory. The means we have described of ascertaining when the material has been brought to the proper condition of dryness is the best and most convenient of which we are aware, and if carefully observed will enable the operator to accomplish the desired result without difficulty.
We do not restrict ourselves to the use of 2.; any alkaline silicate or any oxide, inert material, or coloring substance; and it is .also true that it is not essential that any oxide or inert material be added to the silicate to produce a useful result.
If an oxide, inert material, or coloring substance is employed, the proportions which we have given-thatis to say, about four parts of 'ihe silicate to one part of the inert materialmay be used with satisfactory resu u l is .not to be understood that there can be no departure from these proportions, nor that other formulas involving a use of other oxides orinert substances cannot be made use of.
We do not herein claim, broadly, the use of an ammoniacal bath as described, as the same is made the subject of another application.
What we claim as our invention, and desire to secure by Letters Patent, is-
1. The within-described process of forming 0 articles of an alkaline silicate with or without aninert material, which consists in,first, formadding the inert material; second, desiccating the solution, and, third, subjecting the desiccated compound to pressure in heated molds, substantially as described.
2. The within-described process of forming articles of an alkaline silicate with or without an inert material,which consists in,first, forming a solution of silicate and introducing, if preferred, an inert material; second, removing the aqueous elements in part; third, comminuting the compound; fourth, subjecting the desiccated po er to pressure in heated molds, and, fifth, s bjecting the article to the action of a bath, substantially as set forth.
