Summary

Narrow processing windows were encountered when fine, high surface area, uniformly sized powders were used in injection molding, slip casting, and dry pressing. Conversely, low surface area powders having broad particle-size distributions were determined to have wide processing windows. One sintered reaction-bonded silicon nitride material processed with a powder having these desired properties exhibited a strength of 925 MPa and a Weibull modulus of 22, indicating that good reliabilities are possible when these types of powders are used.
