Abstract

282,403. Singer, F. Dec. 17, 1926, [Convention date]. Clay, porcelain, and like plastic compositions; plastic compositions containing soapstone. - To produce a ceramic material having a low coefficient of expansion, steatite, or other compound of magnesium or of the alkaline earths, is mixed in the solid state with aluminium compounds and heated until three phases are formed, one phase being a glass having, a refractive index of 1.53 to 1.55, and the other two phases being crystallites, the first crystals of the sillimanite type, including mullite, and the second crystals of the forsterite and enstatite type.
