General

Tellurium has two allotropes, crystalline and amorphous. When crystalline, tellurium is silvery-white with a metallic luster. It is a brittle and easily pulverized metalloid. Amorphous tellurium is a black-brown powder prepared by precipitating it from a solution of tellurous acid or telluric acid (Te(OH)6). Tellurium is a semiconductor that shows a greater electrical conductivity in certain directions depending on atomic alignment; the conductivity increases slightly when exposed to light (photoconductivity). When molten, tellurium is corrosive to copper, iron, and stainless steel. Of the chalcogens, tellurium has the highest melting and boiling points, at 722.66 K (841.12 ℉) and 1,261 K (1,810 ℉), respective.

Material Notes

Tellurium Sputtering Targets, Purity is 99.999%; Circular: Diameter <= 14inch, Thickness >= 1mm; Block: Length <= 32inch, Width <= 12inch, Thickness >= 1mm. Some materials and manufacturing methods may yield product with higher than average porosity. Performance may be affected according to process requirements.
