Tellurium/Te Nano Micron Powder Purity 5N Size 200mesh

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.

Tellurium Powder Discription

Tellurium Powder offers high thermal and electrical conductivity.  UrbanMines specializes in producing high purity Tellurium Powder with the smallest possible average grain sizes.The vacuum ball milling technology of UrbanMines can ensure the stable quality of Tellurium Powder with low impurity contents and low oxygen content.Our standard powder particle sizes average in the range of - 325 mesh, -200 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron). We can also provide many materials in the nanoscale range.  such as -100mesh,-200mesh, -300mesh. The different powder variations we offer give you the freedom and flexibility to tailor the properties of Tellurium Powder to your specific application. We also produce Tellurium as rod, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.

What are Tellurium and Tellurium Powder used for?

Tellurium is mainly used in alloy and cast iron,chemical raw materials,other industries as additives. 

Tellurium is also used as a catalyst for ceramic and glass coloring agent, rubber vulcanizing agent, petroleum cracking catalyst, etc..

It is a very promising semiconductor material used for the preparation of tellurium compounds, also used as a catalyst.

Tellurium Powders are useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. 

Common applications for Tellurium Powder also include being used as an additive to stainless steel and copper to improve machinability, as well as in photovoltaic solar panels to convert sunlight into electricity.

Tellurium Powder is also widely used for square thermal analysis cup, casting coating, refrigerating element, infrared detector materials, solar cell material, ect.
