Abstract

Silicon nitride materials are the leading ceramics for structural applications at elevated temperature because of their excellent combination of properties. However, cost is the major impediment for the use of silicon nitride in commercial applications. Sintered reaction-bonded silicon nitride (SRBSN) uses silicon powder as the raw material source and is an attractive alternative to the more conventional approaches that begin with Si3N4 powders. Because of the low silicon powder cost, the process is cost-effective compared to the expensive high-purity powders. The purpose of the present study was to examine the current state of SRBSN materials and determine the effect of different silicon precursor powders and different sintering additives on the processing and final mechanical properties.
