摘要
以纯度99.9%的硒为原料,通过氧化燃烧的方法将原料氧化,利用不同氧化物在水中溶解度的差异对氧化硒进行分离提纯并还原;然后对硒进行深度氧化以除杂质碲,最后采用真空蒸馏提纯工艺制备出纯度达到或超过6N(99.9999%)的高纯硒材料.高纯硒中的杂质含量采用ICP-AES和GDMS进行分析检测.
Use purity of 3N selenium as raw material,oxidized the raw material by oxidize combustion method. Using the different oxides in the water solubility to separate and purified the selenium dioxide and reduce it. And deep oxidation selenium to remove Te impurity. Finally prepared by vacuum distillation 6N （99.9999%） high purity selenium and results were obtained by ICP-AES or GDMS.
