The effect of nitrogen on the α/β phase conversion of Si 3 N 4 ‐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 Si 3 N 4 and AIN without the use of oxide additives (e.g., Y 2 O 3 ).
