Grain Boundary Engineering in Nonoxide Ceramics.

Abstract

The deliberate selection and control of composition, structure, and processes occurring in the grain boundary, both during and after fabrication, with the aim of specific property modification may properly be defined as grain boundary engineering. We will review various strategies for doing grain boundary engineering and give examples of the use of these strategies in the development of hot-pressed silicon nitride. Research needs for further development of grain boundary engineering (GBE) in nonoxide systems are discussed.
