Abstract: As a key material for semiconductors, photovoltaic devices, and infrared detectors, the high-quality purification technology of scattered metal tellurium（Te）directly affects the performance and reliability of downstream products. The research progress of mainstream purification processes was systematically reviewed, including chemical purification（chemical precipitation, solvent extraction, electrorefining, and hydrogenation）and physical purification（vacuum distillation, zone melting, Czochralski purification, and solid-state electromigration）. The applicable scope,advantages, disadvantages, and existing problems of each process were thoroughly discussed, and prospects for future research priorities in high-purity Te preparation were provided. The aim is to promote the optimization and development of high-purity Te preparation technology through a comprehensive review, establish an efficient, low-consumption, and safe Te purification system, and provide core material support for the new generation of electronic information and clean energy industries.
