Tellurium powder is a semi-metallic, lustrous, brittle, crystalline. It is a silver-white metalloid and usually available as a dark grey powder. It has the properties both of metals and the non-metals. Tellurium forms many compounds corresponding to those of sulfur and selenium. When tellurium is burnt in the presence of air and it has a greenish-blue flame. Through this tellurium dioxide is produced. It is also utilized in batteries at very low levels to lead to decreases the corrosive action of sulfuric acid in batteries and to enhance the lead’s strength and hardness.

Tellurium powder does not react with water or hydrochloric acid. However, it only dissolves in nitric acid. Tellurium is often utilized as an additive to steel. Moreover, it is often alloyed to aluminium, copper, lead, or tin. Tellurium is added to lead to enhancing its durability, strength, and resistance to corrosion. It can be used for cast iron; ceramics, blasting caps and it’s alloyed with copper and stainless steel to make these metals more workable.

Tellurium powder: It is employed in solar panels and chalcogenide glasses. Tellurium speeds up the curing process and makes the product less susceptible to aging when it is added into the rubber. It is less likely to be affected by oil, which softens normal rubber. Tellurium is used in alloys to improve their machinability. When added to lead it makes it more resistant to acids and enhances its strength and hardness.

Tellurium powder has been utilized to vulcanize rubber, to tint glass and ceramics. It is employed in rewritable CDs and DVDs. It is also utilized as a catalyst in oil refining. It can be doped with silver, copper, gold, or tin in semiconductor applications. Tellurium is employed as a coloring agent in ceramics. Tellurium is also applied in the electronics industry, for example with cadmium and mercury to form photosensitive semiconductors.

Cadmium telluride (CdTe) is employed as a thin film in solar panels to convert sunlight into electricity. CdTe panels have a high-efficiency rate as compared to amorphous silicon solar panels. It is used in catalysts for petroleum cracking and in blasting caps for explosives.
