Abstract

1277574 Silicon nitride compositions DOULTON & CO Ltd 12 June 1969 [12 June 1968] 27910/68 Heading C7A A heat-resisting article which comprises, by weight, a major proportion of silicon nitride and a minor proportion of mullite (3Al 2 O 3 2SiO 2 ) is made by (a) forming a mixture comprising silicon powder, 1-70% of fugitive binder (e.g. water or an organic binder) and 1-63% of mullite or 1-65% of china and/or ball clay, (b) forming the mixture to shape as by isostatic pressing, die pressing, extrusion, hand tamping, vibratory compaction or slip casting, and (c) fully nitriding. The mixture may also contain silicon nitride powder in an amount of 1-90% based on the weight of silicon powder present.
