Studies of the non-isothermal decomposition of barium2,4,6-trinitroresorecinate monohydrate,Ba(TNR)·H 2 O,were carried out by means of TG-DTA,DSC and IR.The thermal decomposition mechanism and associated ki-netics were investigated.The kinetic parameters were obtained from an analysis of the DSC curves by integral and differential methods.The most probable kinetic model function of the dehydration reaction of Ba(TNR)·H 2 O was suggested by comparison of the kinetic parameters.
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.
