粗碲的真空提纯及生产实践

The Vacuum Distillation and Productive Practice of Crude Telluriumshui

摘要: 基于单炉试验的较佳条件，采用真空蒸馏提纯99%~99.9%的粗碲，经一次蒸馏，产品全部达到99.99%碲标准，碲直收率为97%，回收率>99 %。

Abstract: The 99~99.9 % crude tellurium is purified by vacuum distillation after getting fairly good results from the single-furnace tests. All products of tellurium reaches purification standard (99.99 %) after the first distillation.
