High Purity Zinc

Description

High Purity Zinc Zn 5N 6N 7N, is a shiny silvery-grey transition metal with melting point 420°C and density 7.14g/cm³, which easily soluble in acid, and easily oxidation in room temperature and oxidize fiercely when heating to 225°C, and is of good wear resistance, corrosion resistance, and anti-electromagnetic field performance. High purity zinc of more than 99.999%, 99.9999% and 99.99999% is purified by zone-floating or crystal puling growth purification process. High Purity Zinc 5N 6N 7N at Western Minmetals (SC) Corporation with purity of 99.999%, 99.9999% and 99.99999% can be delivered in the form of single crystals and polycrystalline pieces, shot, granule, ingot, rod and disc which is packed in composite aluminum vacuum bag with carton box outside, or as customized specification to reach the perfect solution.

Applications

High Purity Zinc is in preparation for high technology applications in high purity alloys, reducing agents, the synthesis of nano-materials, an ideal dopants and precursor materials for thin film deposition, advanced microelectronics, solar cells, fuel cells, all kinds of high purity metal salts and high purity metallic organic compounds, and optical materials. High Purity Zinc is primarily used in the manufacturing of crystal growth of compound semiconductors such as Cadmium Zinc Telluride CdZnTe or CZT, and ZnS, ZnSe ,ZnTe, ZnSb base material etc, and in the application of precision casting in automobile industry etc.
