Tellurium is a silver-gray element, somewhere between metals and non-metals. Tellurium Powder is a non-metallic element recovered as a by-product of electrolytic copper refining. It is a fine gray powder made of antimony ingot by vacuum ball grinding technology.
Tellurium, with atomic number 52, is burned in the air with a blue flame to produce tellurium dioxide, which can react with halogen, but not with sulfur or selenium. Tellurium is soluble in sulfuric acid, nitric acid, potassium hydroxide solution. Tellurium for easy heat transfer and electrical conduction. Tellurium has the strongest metalality of all non-metallic companions.
UrbanMines produces pure tellurium with purity range from 99.9% to 99.999%, which can also be made into irregular block tellurium with stable trace elements and reliable quality.The tellurium products of tellurium include tellurium ingots, tellurium blocks, tellurium particles, tellurium powder and tellurium dioxide, purity range from 99.9% to 99.9999%, and can also be customized to purity and particle size according to customer needs.
