Practical Evolutions and Computer Simulation of Pores in BaTiO₃ Ceramics during Sintering Process

Abstract:

Practical evolutions of pores in BaTiO3 ceramics during sintering are studied, including the preparation of practical BaTiO3 ceramics and observation of ceramic microstructure by SEM. The reduction of porosity and thus dense process results from the change of the free energy in the ceramic system, which is altered by the disappearing of the interface between solid and pore. The sintering process are monitored, including sintering neck growth, pore shape and size changing, grain growth and compact body contracting. Theoretical formulae during the sintering process are applied for the computer simulation. The experimental results of BaTiO3 ceramics are in good agreement with that of simulation.
