Two-Particle Sintering Models and Their Application

Popis výsledku v původním jazyce

Models of sintering are mainly used to study the sintering kinetics, to analyze the densification, and to evaluate the effects of various processing parameters. During sintering the individual particles bound together and a denser and stronger monolithic ceramic material is formed. Simulations of influence of various materials, kinetic and thermodynamic characteristics on the mechanism of sintering carried out on simplified geometries plays a great role in the understanding of this mechanism. Nevertheless, the ability to predict sintering behavior for a given set of parameters still remains unsolved and poses a challenging task. The current paper is based on recent works and presents a general model and analytical expressions for micromechanical sintering of two particles. General problem statements for surface diffusion, grain boundary diffusion, and lattice diffusion are formulated. The main relations for processes that take place during sintering are given. Possible boundary conditions due to pores geometries and neck formation are discussed, and possible applications of the sintering models in our future research are outlined.
