摘要
The effect of nitrogen on the alpha / beta phase conversion of Si//3N//4-based, pressure-sintered bodies was investigated using nitrides and oxides as additives. When stable oxides are used, the alpha / beta conversion is promoted, but when stable nitrides are present, the conversion is inhibited. alpha -Sialon can also be made from Si//3N//4 and AlN without the use of oxide additives.
