| 摘 要： | 以氢氧化铝为原料,氯化钠-氯化钾为熔盐,在1 000℃保温4 h,熔盐加入量为70%时,得到了结晶完整的片状α-Al2O3,片的边长为5～10μm,厚度为0.6～1.4μm;研究了氧化钙对试样物相和形貌的影响。结果表明:氧化钙的加入阻碍了氧化铝向α相转变,阻碍片状氧化铝的生成。

| Abstract: | The crystal plate-like α-Al2O3 was obtained at 1 000 ℃ for 4 h by adding 70% NaCl-KCl molten salt,whose size range is 5～10 μm and the thickness is 0.6～1.4 μm.The effects of calcium oxide on alumina phase and morphology were studied.The result indicated the transition of alumina to α phase was hindered and few plate-like α-A12O3 was obtained by adding calcium oxide. |
