Notes:
Practical evolutions of pores in BaTiO3 ceramics during sintering are studied, including thepreparation of practical BaTiO3 ceramics and observation of ceramic microstructure by SEM. Thereduction of porosity and thus dense process results from the change of the free energy in the ceramicsystem, which is altered by the disappearing of the interface between solid and pore. The sintering processare monitored, including sintering neck growth, pore shape and size changing, grain growth and compactbody 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
