Tellurium (Te) is a quasi-metallic species with the elemental symbol Te. Its name comes from Tellus, meaning "land", which was discovered by F.J.Muller von Reichenstein in 1782. Tellurium is a silvery-white crystal, soluble in sulfuric acid, nitric acid, royal water, potassium cyanide, potassium hydroxide; insoluble in cold water and hot water, carbon disulfide. High-purity tellurium is made from tellurium powder and refined by sodium polysulfide with a purity of 99.999%. For semiconductor devices, alloy, chemical raw materials, and cast iron, rubber, and glass industries as additives.
High-purity and ultra-high purity Tellurium (Te) materials are crucial components for the research, development, and production of advanced technologies which require optimum properties, performance, and quality.
Tellurium granule is made from Tellurium Ingot, it presents the properties of metal while having non-metallic characteristics. It has a spherical granule and irregular granule. Tellurium Granule can be produced in size range from 0.5mm to 10mm, and fine sizes 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 that exhibits both metallic and non-metallic traits. The 99.99% grade is an irregular shape and made by a 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.
Tellurium is crucial a component for the research, development, and production of advanced technologies.
80% of tellurium consumption is used in the metallurgical industry: steel and copper alloy can improve its cutting performance and increase hardness; tellurium in white cast iron is used as carbide stabilizer to make the surface strong and wear-resistant; lead-containing small tellurium can improve corrosion resistance, wear-resistance, and strength of materials and serve as the sheath of submarine cable; lead adding tellurium can increase lead hardness to make battery plate and printed lead. Tellurium can be used as an additive for a petroleum cracking catalyst and as a catalyst for making ethylene glycol. Tellurium oxide is used as a colorant for glass. High-purity tellurium can serve as the alloy composition of the temperature difference electric material. Bismuth telluride is a good refrigeration material. Tellurium and several tellurides are semiconductor materials. Ultra-pure tellurium single crystal is a new type of infrared material.
In addition, in timing explosives, tellurium is a fuse for the delayed explosion. As a raw material for manufacturing fungicide, tellurium in medical treatment can also extract isotopes of iodine to cure thyroid diseases.
Catalysts mainly used for petroleum cracking, the luminance of plating liquid, and glass coloring materials are added to steel to increase its ductility and to lead to increasing its strength and corrosion resistance. Tellurium and its compounds are also semiconductor materials.
