The effect of nitrogen on the α/β phase conversion of Si3N4‐based, pressure‐sintered bodies was investigated using nitrides and oxides as additives. When stable oxides are used, the α/β conversion is promoted, but when stable nitrides are present, the conversion is inhibited. α‐Sialon can also be made from Si3N4 and AIN without the use of oxide additives (e.g., Y2O3).
