摘　　要：初步考察了金属锆粉末在M (OH) 2 (M =Sr,Ba)介质中的水热氧化过程 .结果表明 ,钙钛矿型氧化物MZrO3(M =Sr,Ba)的生成规律与常规水热合成基本相同 .对金属锆水热氧化过程的初步分析表明 ,ZrO2 ·xH2The hydrothermal oxidation process of Zr metal powders was investigated under M(OH) 2(M=Sr,Ba)medium. The results indicated that perovskite-type MZrO 3(M=Sr,Ba)oxides were the main products, and their forming regularity was in good agreement with that of conventional hydrothermal synthesis. According to the preliminary analysis of the oxidation process, ZrO 2·xH 2O as an intermediate product was important.
