该通讯报告了在环境压力下形成氧化铟(III) 的高压变体（所谓的刚玉型或六方In2O3）。刚玉型In2O3是通过加入浓氨溶液从硝酸铟的甲醇溶液中沉淀出来，然后将所得沉淀物在250-500℃下煅烧而获得的。讨论了杂质和添加剂在稳定刚玉型In2O3 中的作用。
This communication reports the formation of the high-pressure modification of indium (III) oxide (so-called corundum-type or hexagonal In2O3) under ambient pressure. Corundum-type In2O3was obtained by precipitation from the solution of indium nitrate in methanol by adding concentrated ammonia solution and subsequent calcination of the obtained precipitate at 250−500 °C. The role of the impurities and the additives in the stabilization of corundum-type In2O3is discussed.
