Resumo

Abstract The thermal decomposition of crystalline antimonic(V) acid (C-SbA) was studied by means of DTA, DSC, and DTG. The amount of water evolved from the heated C-SbA was determined by the Karl Fischer method. The material heated in the range of 600–1000 °C is Sb6O13, neither Sb3O6(OH) nor H2Sb12O26. The thermal decomposition of C-SbA consists of four dehydration and two reduction steps up to 1000 °C.
