Patent GB-621480-A (GB)
Title: Vitreous compositions of matter, and methods of making the same
Filed: 1945-10-31
Abstract: To avoid the pick-up of silica during the grinding of alumina forming the main constituent of compositions for making vitreous products such as spark plug insulators, a rubber-lined mill is used, having fired alumina grinding balls instead of quartz stones.ALSO:In the manufacture of vitreous products such as spark plug insulators for high compression internal-combustion engines, the vitreous composition comprises at least 92 per cent (by weight of the fired product) of alumina, at least 1 per cent of chromium oxide, at least 3.5 per cent of clay, and a remainder, preferably including more than three, of the oxides or other compounds of metals selected from a specified list; alkalis of Group I of the periodic table are excluded except to a maximum equivalent to 0.05 per cent of the oxides thereof.  Examples of batches are given containing alumina, plastic ball clay, chromium oxide, calcium fluoride or carbonate, and magnesium phosphate or silicate; one example also contains barium carbonate and beryllium silicate. The silica content should if possible not exceed 0.05 per cent: this may be ensured by the use of a rubber-lined mill having fired alumina grinding balls instead of quartz stones, and, when a metallic silicate forms an ingredient, by the inclusion of a fluoride whereby gaseous silicon tetrafluoride is driven off during firing.  The ingredients may be calcined separately or in combination and then reground, before the final body is formed and fired.
