摘要：

A complex perovskite of Sr(CuxZn1-x)1/2W1/2O3 (SCZW) is synthesized by a new combination of wet and dry processes. Mixed oxides containing Cu2+ and Zn2+ (CZ) are prepared by the wet process (coprecipitate method). SCZW is obtained by the dry process (mixed-oxide method) from a mixture of CZ, SrCO3, and WO3. SCZW has practically no compositional fluctuation, unlike solid solutions prepared by the conventional dry method. The wet-dry process method is useful because the wet process is applied to only B-site cations having the same valence.
