Abstract

11,771. Podszus, E. May 17, 1911, [Convention date]. Pottery; pottery materials.-Ceramic or,fireproof bodies not containing clay are manufactured from the rare earths, aluminium oxide, quartz, magnesia, thorium oxide, zirconium oxide, and other difficultly soluble oxides and mixtures thereof by working the base material, reduced to a degree of fineness of 0À005 to 0À0001 mm. or less, to a liquid or paste with a' colloid solution of the base material or of one of the other substances specified. The product may be subsequently fired. The colloidal solution is preferably produced in the presence of the finely ground powder; for example, thorium oxide may be mixed with a solution of thorium or zirconium nitrate, the acid being subsequently eliminated by dialysis or by evaporation, the acid and water being replaced. After some time only water is added so that the acid is gradually driven off. The powder is finally allowed to settle and is then washed. As binding-agents, colloidal forms of magnesium hydroxide, thorium hydroxide, aluminium hydroxide from aluminium acetate, and silicic acid from sodium silicate and hydrochloric acid, are among the substances referred to. In some cases gelatine, gum, &c. may be used as subsidiary binding-agents, in quantity more than 0À5 per cent. Not less than 0À3 per cent. of alkali or acid should be used in making the colloidal solution. The process may be applied for improving the plastic qualities of materials of low placticity or for reconverting already burnt material to a plastic state. The Specitication as open to inspection under Section 91 (3) (a) comprises also the following. When colloidal solutions are used as binding-agents, for example thorium hydroxide, in place of evaporating the acid by means of heat it may be done in the cold and the process may be hastened " by allowing alkaline reactions to act upon the mass from time to time." This subject-matter does not appear in the Specification as accepted, but part of it forms the subject of the divided application 23,577/12, [Class 87 (ii), Moulding plastic &c. substances].
