High purity tellurium is a chemical element that has the symbol Te and atomic number 52. A brittle, mildly toxic, silver-white metalloid which looks similar to tin, tellurium is chemically related to selenium and sulfur. Ellurium must be packed by anti-damp packing paper , placed into wooden box or galvanized iron bucket. Same grade tellurium should be put into the same box. The net weight of each box should not be more than 25kg. Imparts garlic-like odor to breath, can be depilatory. It is a p-type semiconductor and its conductivity is sensitive to light exposure.
Manufacturer of thin film & PVD materials. Products include sputtering targets, crucible inserts, e-beam gun replacement parts, ion implantor source replacement parts & backing plates. Te has two allotropes that are crystalline and amorphous .crystalline te has metal luster, silvery colour, fragile. Property.the amorphous te powder is dark grey, and it 3 has medium density ( 6.240g/cm ) , lower melting and boiling point ( 449.6℃ 989.9℃). Te is non-metallic element , but has good heat transfer and electric conductivity . Among all the non-metallic element, te has good metallic property.
Materials used include aluminum, aluminum alloys, barium, barium alloys, bismuth, bismuth alloys, boron, boron alloys, cadmium, cadmium alloys, calcium, calcium alloys, carbon, cerium, cerium alloys, cesium alloys, chromium & chromium alloys. Tellurium is widely used in metallurgical applications, and is primarily alloyed with iron, copper and lead. Tellurium is also used in cadmium telluride (CdTe) solar panels. Alloys of tellurium are also used to create semiconductor materials, as well as other electronic materials. It is mainly used for preparation of thermoelectric conversion elements, refrigeration components, piezoelectric crystals, and infrared detectors. Packed with Dacron film, and then covered with a plastic bag or vacuum sealed in a glass ampule.
