Abstract

Atomic structures of amorphous silicon nitride based ceramics were simulated by the molecular dynamics method. Effects of carbon and/or boron addition on diffusion behavior in the amorphous state were investigated. Based on the results obtained, the observed excellent thermal stability of the amorphous state was discussed.
