Silvery White Corrosion Resistant Metals , 7N Tellurium Lump High Purity Metals

Silvery White High purity Tellurium , 7N Tellurium Lump For Ceramic
Product Description

Tellurium is a kind of minor metal,showing greater conductivity in certain directions which is used as raw material in semi-conductor material, It is a brittle and easily pulverized metalloid. When crystalline, tellurium is silvery-white and when it is in pure state it has a metallic luster.

Xinrong Materials specializes in producing purified Tellurium (99.99% to 99.99999%), and in powder,shot, ingot and lump forms.

Amorphous tellurium is found by precipitating it from a solution of tellurous or telluric acid (Te(OH)6).

Tellurium is a semiconductor that shows a greater electrical conductivity in certain directions which depends on atomic alignment, the conductivity increases slightly when exposed to light. When in its molten state, tellurium is corrosive to copper, iron and stainless steel.
