產(chǎn)品名稱：氧化釔(Y2O3) 性質(zhì)：白色略帶黃色粉末。相對(duì)密度5.01。熔點(diǎn)2410℃。不溶于水和堿，溶于酸。露置空氣中易吸收二氧化碳和水。 用途：主要用于制造單晶、釔鐵石榴石、釔鋁釹石榴石等復(fù)合氧化物，這些復(fù)合氧化物由于高頻性能好，可作為微波用磁性材料及軍事通信工程用的重要材料。也可用磁性材料及軍事通信工程用的重要材料。也可用作高級(jí)光學(xué)玻璃添加劑制高溫透明玻璃、陶瓷材料添加劑、X光增感屏稀土熒光粉、大屏幕電視用高亮度熒光粉和其他顯像管涂料。此外還用于制造薄膜電容器和特種耐火材料，以及高壓水銀燈、激光、貯存元件等的飽磁區(qū)材料。 Properties:Y2O3slightly yellow and white powder. Density 5.01. 2410 ° C melting point. Do not dissolve in water and alkali and dissolved in acid. Uses:Yttrium Oxide also called Yttria, high purity Yttrium Oxides are the most important materials for tri-bands Rare Earth phosphors which give the red colour in colour television & computer tubes. In optical industry, the Yttrium Oxide is used to produce yttrium-iron-garnets, which are very effective microwave filters. Low purity of Yttrium Oxide are widely applied in electronic ceramics   化學(xué)分析 ： 相對(duì)純度(Purity): 99.99% 稀土總量(TREO):≥99% 稀土雜質(zhì)含量(RE.Impurities) 非稀土雜質(zhì)含量 (Non--RE.Impurities) La2O3     ＜10PPM CeO2      ＜10PPM Pr6O11     ＜10PPM Nd2O3     ＜10PPM Sm2O3     ＜10PPM Eu2O3     ＜10PPM Gd2O3     ＜10PPM Tb4O7     ＜10PPM                       Dy2O3     ＜10PPM  Ho2O3     ＜10PPM Er2O3     ＜25PPM Tm2O3     ＜10PPM Yb2O3     ＜10PPM Lu2O3     ＜10PPM Fe2O3    ＜3PPM CaO     ＜190PPM Cl-      ＜150PPM SiO2     ＜20PPM ZnO     ＜5PPM PbO     ＜3PPM NiO     ＜3PPM CuO     ＜3PPM L.O.I       1%
