Abstract

139,315. British Thomson-Houston Co., (General Electric Co.). March 13, 1919. Refractory substances containing rare earth oxides.-Oxides of rare-earth metals are used in place of some or all of the free silica in the manufacture of porcelain. Suitable oxides are those of zirconium and titanium. Zircite cement, a compound containing about 81 per cent zirconia, 14 per cent silica, and small quantities of other oxides, may also be employed. A typical example contains 35 per cent feldspar, 45 per cent clay, and 15 per cent zirconia.
