N2 - The intergranular microstructure of liquid phase sintered silicon nitride based ceramics is a consequence of the oxynitride liquid that forms during sintering. A tailored starting powder composition containing a combination of metal oxide and nitride additives that would form an oxynitride glass-ceramic may result in a liquid phase sintering medium that is readily crystallized after densification leaving a minimum of residual glass. This work is concerned with the incorporation of B-phase, which is a five-component phase, into the intergranular regions of silicon nitride ceramics.
