异丙醇钇的制备及性能研究

采用金属钇与异丙醇直接反应法制备异丙醇钇，采用异丙醇钇溶胶－凝胶法制备氧化钇粉体。通过ＩＲ、ＸＲＤ、ＴＥＭ分析手段研究了粉体的结构与形貌，研究结果表明：采用金属与醇直接反应法可以制备异丙醇钇；ＩＲ和ＸＲＤ结果证明了制得的醇盐水解煅烧产物分别为氢氧化钇和氧化钇；氢化钇的显微形貌为同米级不规则小颗粒组成的网状结构，而氧化钇则呈分散的微米级粒状。

Study on Preparation and Properties of Yttrium Isopropoxide

Yttrium Yttrium isopropoxide was synthesized from yttrium and ioproxide by direct reaction. Yttria powders were prepared from yttrium alkoxide by sol-gel process. IR, XRD and TEM studied their structures and morphologies. The results showed that: yttrium isopropoxide could be prepared by direct reaction of metal and alcohol. IR, XRD results investigated that hydroxide yttrium and yttrium could be obtained after hydrolyzing and sintering. The morphologies of hydroxide yttrium powders were network structures formed by irregular particles, those of yttria powders were single particles.
