Synthesis and thermal decomposition of scandium hydrogenphosphite Sc2(HPO3)3

▸ TG-DTA and TG-MS of hydrogenphosphite under inert conditions. ▸ On heating, consecutively release of hydrogen and phosphorus accompanied by the formation of crystalline phosphates, ScPO4 and Sc(PO3)3. ▸ After hydrogen release intermediate formation of red-transparent nano crystalline aggregates.
