| Abstract: | Volatilization resulting from the thermal decomposition of Si3N4 causes the large weight loss and desintering phenomenon observed during pressureless sintering of Si3N4-5% 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 Si3N4 components. |
