Tellurium is a kind of minor metal, showing greater conductivity in certain directions which is used as raw material in the semiconductor material, It is a brittle and easily pulverized metalloid. When crystalline, tellurium is silvery-white and when it is in the pure state it has a metallic luster.
Amorphous tellurium is found by precipitating it from a solution of tellurous or telluric acid (Te(OH)6).
Xinrong Materials specializes in producing purified Tellurium (99.99% to 99.99999%), and in powder, shot, ingot and lump forms.
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.
