摘要: A method of producing a silicon nitride article by powder techniques, wherein is used as starting material. The powder, mixed with densification aid, heated rapidly to the sintering/densification temperature (1500° 1750° C) in absence pressure, held there short, closely controlled time (5 30 minutes) and thereafter cooled. This provides strong product dimensional tolerances.
