High purity tellurium and high purity tellurium dioxide show that product purity is more than 4 N of tellurium and tellurium dioxide. Its widely used in sensors, solar cells, conductive silver pulp, glass doped, infrared detection, etc. Main preparation methods of high purity tellurium included vacuum distillation, zone melting method, direct pull purification method, solution reduction method, electrolytic method, extraction. High purity tellurium dioxide preparation methods mainly contain chemical method. This paper introduces the main preparation methods of high purity tellurium and high purity tellurium dioxide and its characteristic, and the high purity tellurium and high purity tellurium dioxide industry development foreground is prospected.
