Tellurium Dioxide is a solid oxide of tellurium, which is pure white color with purity of 99.99%. 99.9% Tellurium Dioxide is little yellowish powder compared with 99.99% Tellurium Dioxide due to the higher content of heavy metals content. High purity 99.99% Tellurium Dioxide with low heavy metal contents and non existing acid ions, so that it does not corrode metals and can increase product durability.
Tellurium powder is gray fine powder made by technologies of vacuum ball milling with low oxygen content and high quality. Tellurium powder is insoluble in water, benzene and carbon disulfide, but it is soluble in alkali, concentrated sulfuric acid and nitric acid. We can provide various particle size ranges from 60 mesh to 100, 200, 325 and 500mesh.
Tellurium granule is made from Tellurium Ingot, it presents the properties of metal, while having non-metallic characteristics. It has spherical granule and irregular granule. Tellurium Granule can be produced in size range from 0.5mm to 10mm, and fine size like 0.5mm to 1.5mm, 1mm to 3mm, 1mm to 10mm are our typical type of Tellurium Granule.
Tellurium Lump is a rare, silvery-white, semi-metallic element which exhibits both metallic and non-metallic traits. The 99.99% grade is irregular shape and made by physical crushing machine. While, high purity grades of 99.999% and 99.99999% are made by distillation technology and shape form is like roofing tile. We can supply Tellurium lump purity range from 99.99% to 99.99999%.
Tellurium Ingot is a heavy and rare minor metal that is used in steel alloys and as a light-sensitive semiconductor in solar cell technology. Tellurium does not react with air or water and, in molten form, it is corrosive to copper, iron and stainless steel.
