Method for production of sintered article of silicon nitride.

摘要

As the aluminium nitride component of a sintering aid for powdered silicon nitride, either a spinel type compound having oxygen dissolved in aluminium nitride to form a solid solution or a poly-type aluminium nitride is used. Since the compound is highly stable in water, it can be effectively used in the form of an aqueous slurry mixture. As the sintering aid, this compound is used as effectively as aluminium nitride.
