isothermal atmosphere
1.The non isothermal decomposition process and decomposition kinetics of analginum in static atmosphere were studied by TG DTG techniques. The middle and finial product were determined by TG DTG curves and IR diagrams. The data were analysized by differential and integral methods.
2.The oxidation of CaS was studied in the temperature range of 970~1150℃ under O2 atmosphere with different O2 concentrations. Experiments were carried out by a Metteler Toledo TGA instrument under isothermal condition and the exhausted gas was analyzed by the infrared spectral method.
