Abstract

322,361. Marks, Sir G. C., (A.C. Spark Plug Co.). Dec. 17, 1928. Plastic compositions containing artificial corundum, clay, lithium compounds.-A refractory body is made by melting, e.g. in an electric arc, a mixture of alumina, clay and a lithium compound, and cooling rapidly to reduce the size of crystals, the proportion of alumina to silica being preferably greater than that in mullite. An example of proportions is alumina 60 per cent, clay 35 per cent and lithium oxide 5 per cent. The alumina may be partly replaced by clay or a zirconium compound and other ingredients such as chromium oxide. The lithium compound may be partly replaced by or used in addition to magnesium oxide, zirconia or beryl. The material thus produced may be ground and used as grog preferably with an equal proportion of clay in the manufacture of a porcelain for insulators such as sparking plugs &c.
