Tellurium purification: various techniques and limitations

[摘要] Limitations and techniques to purify tellurium metal especially using non-chemical techniques such as vacuum distillation and zone refining are discussed. It was found that the clean environments, design, handling and cleaning of quartz ware are equally important in achieving the desired purity levels.
