Silicon nitride blast nozzle

It is often difficult to assess and compare the industrial importance of refractory carbides and nitrides. In some cases, the analysis is relatively straightforward. A case in point would be a silicon-nitride blast nozzle. The cost of producing such a part can be exactly determined and its advantages over a metal unit in terms of wear resistance and useful life accurately plotted. 

In other useful applications, silicon nitride bearings have been found to offer excellent performance silicon nitride cutting tool inserts are a commercial product wear parts such as sand blast nozzles, seals, and die liners are also commercially produced the superior performance of heat exchangers has been demonstrated and there are also military applications.
