Abstract
The process of thermolysis of double strontium-tin(IV) hydroxide obtained by precipitation from hydrochloric acid solutions by adding ammonia to pH=10 and the phase composition of its degradation products were studied by differential thermal analysis, X-ray phase analysis and scanning electron microscopy. It was shown that the main stages of dehydration are completed at about 350°C and as a result of thermolysis an X-ray amorphous product is formed, which at temperatures above 700°C transitions to the strontium stannate crystalline phase.
