摘要：High-purity Na2SnO3 has been prepared by a novel process of roasting SnO2 and Na2CO3 in a solid state under CO–CO2 mixed gas. In the current study, the phase evolution of tin oxides and Na2CO3 roasted under various CO–CO2 atmospheres was investigated by chemical and X-ray diffraction analysis. Under the CO content of 5–20 vol% and temperature over 800°C, Na2CO3 can react with SnO2 and the intermediate products of SnO and Sn to form Na2SnO3. SnO would be decomposed into SnO2 and Sn at temperatures below 800°C; however, the decomposition reaction was effectively restrained by Na2CO3 over 800°C.
