Tellurium Products

Tellurium Metal, Chemicals, and Alloys


Vital Materials produces Tellurium in various shapes and sizes, from powder to pellets to ingots and a wide range of purity from 99.5% to 99.999%. Vital Materials also produces chemicals and compounds derived from tellurium such as tellurium dioxide for industrial applications and other specialty products such as cadmium telluride and telluric acid. Vital Materials’ products can be tailor-made to customer specifications.

Properties

Tellurium has two forms, crystalline and amorphous. Crystalline tellurium is silvery-white and brittle with a typical metallic luster. Amorphous tellurium is a black-brown powder prepared by precipitating it from tellurium or tellurous acid solution. Tellurium is very corrosive to copper, iron, and stainless steel in the molten form. Tellurium also has semiconductor properties.


Applications

  • Solar cells: Tellurium is used in solar cells when alloyed with Cadmium as Cadmium Telluride which is used in the production of Photo-Voltaic Thin film Solar panels. In the past few years, the consumption volume has increased significantly and is today the biggest global consumer of tellurium.
  • Thermo-electric: Alloyed with bismuth (Bi2Te3) or lead (PbTe) it has applications in the electronic and thermo-electric fields. PbTe is also used in far infrared detectors.
  • Metallurgy: Adding in small amounts tellurium improves the machinability of stainless steels, steels and copper.
  • Rubber: Tellurium compounds are used in the vulcanization of rubber.
  • Tellurium is used in rewritable optical discs (CD-RW, DVD-RW, Blu-ray Discs) and in random access memory chips (PRAM).
  • High purity tellurium can be used to prepare X-ray detectors.
Tellurium is mostly recycled from the CdTe industry and thermoelectric scraps.
