On the Kinetics of Densification during Liquid Phase Sintering of Si3N4

  • J. Pabst

Abstract

The classical model for describing sintering kinetics has already been developed by Kingery1 in 1959, who divided the sintering process into three sequential processes, rearrangement,solution/reprecipitation and coalescence, and formulated temporal laws for all stages. This paper will try to investigate the possibility of application of the Kingery law (three sequential processes, power law for the solution/ reprecipitation step) for describing the densification of Si3N4-powders and reaction bonded silicon nitride (RBSN) during sintering.
