摘要
Thermal decomposition reaction mechanism of the precursor gel made by sol gel process for nano crystalline BaTiO3 was studied by TG DTG and FTIR techniques.The reaction proceeded in three stages:solvents removing,organic ligands decomposing,and amorphous solid BaTiO3 forming.The differential and intergral mechanism functions and activation energy for the third stage were obtained by calculation and comparson.
