Basic Mechanisms of Liquid Phase Sintering

  • G. Petzow
  • W. A. Kaysser

Abstract

A review on the present state of liquid phase sintering in ceramic and metallic systems is given. It is shown how the densification phenomena i.e. rearrangement and center to center approach can occur by the elementary mechanisms of particle disintegration, Ostwald ripening and shade accommodation as well as directional grain growth. The influence of driving forces provided by chemical reaction on the kinetics of mass transfer is discussed.
