What is Telluride powder?
Tellurium, the element symbol is Te, molecular weight 127.6, melting point 452 ℃, boiling point 1390 ℃, water solubility: insoluble in water; density 6.25×10³kg/m³, appearance: silvery white solid, applications: as semiconductor materials, catalysts, etc.
Tellurium is a quasi-metal with the elemental symbol Te. Its name is derived from tellus, meaning “land,” and was discovered by F.J. Müller von Reichenstein in 1782. Tellurium is a rhombohedral silver-white crystal, soluble in sulfuric acid, nitric acid, aqua regia, potassium cyanide, and potassium hydroxide; insoluble in cold and hot water, carbon disulfide. High-purity tellurium is obtained by refining tellurium powder with sodium polysulfide extraction, with a purity of 99.999%. It is used as an additive in semiconductor devices, alloys, chemical materials, cast iron, rubber, glass, and other industries.
Tellurides are compounds of tellurium and metals or nonmetals. For example, the representative of non-metal-containing telluride is hydrogen telluride, which is a colorless, odorous and poisonous gas; the metal telluride has copper telluride, which is insoluble in water.
We have telluride powders such as bismuth telluride, zinc telluride, tungsten telluride, molybdenum telluride, etc.
Application of telluride powder
Tellurium is widely used, and its downstream industries include solar energy, alloys, thermoelectric refrigeration, electronics, rubber and other industries. The application of tellurium in the metallurgical industry accounted for 42% of the total application. Due to the rapid development of tellurium in the photovoltaic field, the proportion of the metallurgical industry is on a downward trend.
The chemical industry accounts for approximately 21% of total tellurium applications. In the chemical industry, tellurium and tellurium compounds are used as additives for catalysts and as dispersants in the rubber industry to improve the strength and elasticity of rubber.
Tellurium accounts for approximately 8% of the electrical and electronics industry. In the optoelectronic industry, semiconductor components such as ZnTe, CdTe, HgTe, HgCdTe, etc. are used in lasers, photodiodes and light receivers involving the infrared to ultraviolet spectrum.
