英文摘要:

      The thermal behavior of synthetic schoenite (K2SO4. MgSO4. 6H,2) during heating has been studied by thermoanalysis methods. the temperatures of dehydration and decomposion of schoenite have also been determined by DTA, TG and DSC.The thermoreaction equations and the X-ray powder diffraction results of the products have been given and the corresponding kinetic parameters have also been obtained.
