Specifications:
High purity tellurium dioxide in white color is crystal powder and not absorb the water, melting point 733 ℃. Tellurium and its compounds are of semiconductors in the electronics industry. Mainly for semiconductor devices, black metallurgy, alloy, chemical raw materials and cast iron, rubber, glass, electronic industries with as additive. In addition, tellurium also can make plating solution of brightener, petroleum cracking catalysts, ceramic and glass coloring. Added to the steel can increase ductility. Add to plumbum to increase strength and corrosion resistance. Or rubber vulcanization agent, manufacturing photoconductive resistance, si-based ones, thermoelectric, electronic refrigeration, semiconductor materials. In cold casting, cutting, metal coating, biological and medical in the process of the application. TeO2(99.9%)
