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%。
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.
