WMC is of expertise in developing and specializing in preparation and purification of metals, oxides and compounds to 4N, 5N, 6N and 7N purity which is in fabricated form of lump, rod, granule, powder, sheet, wire and ingot. All the material is qualified by the analysis of ICP-MS, GDMS and other advanced instruments domestically and internationally.
It is always our goal to be a consistent, reliable and an affordable source for global material requirements at any time. Tellurium is odorless, silvery white color crystalline solid material. High purity tellurium of 99.999%, 99.9999% and 99.99999% ( 5N 6N 7N) is primarily used in the manufacturing of  II-VI compound semiconductor materials, piezo-crystals, cooling elements, thermoelectric converting elements, infrared and γ-ray detectors etc.
