What is Tellurium?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Telluriumwhich has developed particularly rapidly in recent years. Do you know about Tellurium?
The official answer:Tellurium is a quasimetal with the element symbol Te. Its name derives from tellus, meaning “land”, and was discovered in 1782 by F.J. Müller von Reichenstein. Tellurium is an orthorhobic silver-white crystal, soluble in sulfuric acid, nitric acid, aqua regia, potassium cyanide, potassium hydroxide; Insoluble in cold and hot water, carbon disulfide. High purity tellurium is obtained by extracting and refining with sodium polysulfide with tellurium powder as raw material, and the purity is 99.999%. It is used for semiconductor devices, alloys, chemical raw materials and cast iron, rubber, glass and other industries as additives.
What’s the application of Tellurium?
80% of tellurium consumption is applied in the metallurgical industry: steel and copper alloys add a small amount of tellurium, which can improve their machining performance and increase hardness; Tellurium is used as a carbide stabilizer in white cast iron, making the surface strong and wear-resistant; Lead containing a small amount of tellurium can improve the corrosion resistance, wear resistance and strength of the material, and is used as a sheath for submarine cables; The addition of tellurium to lead can increase the hardness of lead, which is used to make battery plates and print lead letters. Tellurium can be used as an additive to petroleum cracking catalysts and as catalysts for the preparation of glycol. Tellurium oxide is used as a colorant for glass. High-purity tellurium can be used as an alloy component of thermoelectric material. Bismuth telluride is a good refrigeration material. Tellurium and some tellurides are semiconductor materials. Ultrapure tellurium monocrystalline is a new type of infrared material.
Besides, in timed explosives, tellurium is also a fuse for time-delayed explosions. As a raw material for the manufacture of fungicides, tellurium can also extract isotopes of iodine in medical treatment and cure thyroid diseases.
It is used for catalysts for petroleum cracking, brighteners for electroplating solutions, and coloring materials for glass, which are added to steel to increase its ductility, and added to lead to increase its strength and corrosion resistance. Tellurium and its compounds are in turn a semiconductor material
