Product Description
Tellurium (Te)
1, Physical character:
When crystalline, tellurium is silvery-white and when it is in pure state it has a metallic luster. It is a brittle and easily pulverized metalloid. 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 (photoconductivity). When in its molten state, tellurium is corrosive to copper, iron and stainless steel.
2, Specification:
High Purity Tellurium:
Te-05 Grade 99.999. The content of Tellurium is above 99.999%. The total impurity element of AG, Al, Bi, Ca, Cr, CD, Cu, Fe, Mg, Mn, Na, Ni, Pb, Se, Si & Zn is bellow 10 ppm;
Uitra Purity Tellurium:
Te-06 Grade 99.9999. The content of Tellurium is above 99.9999%. The total impurity element of AG, Al, Bi, Ca, Cr, CD, Cu, Fe, Mg, Mn, Na, Ni, Pb, Se, Si & Zn is bellow 1 ppm;
Uitra High Purity Tellurium:
Te-07 Grade 99.99999. The content of Tellurium is above 99.99999%. The total impurity element of AG, Al, Bi, Ca, Cr, CD, Cu, Fe, Mg, Mn, Na, Ni, Pb, Se, Si & Zn is bellow 0.1 ppm.
3, Physical Size:
Lump, Ingot, Powder.
4, Application:
The largest consumer of tellurium is metallurgy, where it is used in iron, copper and lead alloys. When added to stainless steel and copper it makes these metals more machinable.
Tellurium is used in cadmium telluride (CdTe) solar panels
Alloyed with both cadmium and mercury, to form mercury cadmium telluride, an infrared sensitive semiconductor material is formed.
Rubber can be vulcanized with tellurium instead of sulfur or selenium. The rubber produced in this way shows improved heat resistance
