Mechanism and caloric effects of the GdCl3∙6H2O crystal hydrate thermal dehydration process
Synchronous thermal analysis and mass spectrometry were applied for complex investigation of the thermal dehydration of crystal hydrate GdCl3∙6H2O. The certified samples were used. The mechanism was established and the caloric effects of the occurred chemical reactions were determined. The thermal decomposition of the crystal hydrate GdCl3∙6H2O was shown to be accompanied by a hydrolysis reaction, resulted in the GdOCl oxychloride formation.
