The thermal stability of carbonate precursors of yttrium oxide was studied by thermal and thermogravimetric analyses, specifically, with evolved gas mass spectroscopy, on TA Instruments equipment. The thermolysis of Y2(CO3)3 · nH2O (n = 2.46) is a complex process and comprises several stages of elimination of water (90–285°C) and carbon dioxide.
