Abstract

Method of making an assembly of two pieces of silicon nitride joined together comprises sprinkling a mixture of alpha-silicon nitride contg. is not >25 wt. % flux onto a first piece of silicon nitride and hot pressing. Pref. the flux is MgO and it comprises 1-5 wt.% of the mixture. The hot pressing is carried out at 1400-1750 degrees C.
