Volatilization resulting from the thermal decomposition of Si 3 N 4 causes the large weight loss and desintering phenomenon observed during pressureless sintering of Si 3 N 4 ‐5% MgO and sialon (z =2)‐5% MgO. The addition of a few weight percent of Si to the powder suppresses this volatilazation and helps to achieve fully dense Si 3 N 4 components.
