Summary
The high costs of Si1N4 powders are driven extensively by achieving low impurity, especially oxygen, levels which can limit high-temperature, but not necessarily room temperature, properties. High Si3N4 powder costs seriously limit lower temperature, e.g., wear, applications, which do not necessarily require such costly material. Therefore, a program was undertaken to develop significantly lower cost Si3N4. Densities, phase contents, microstructure, and room temperature mechanical properties are reported showing good promise of this development.
