Short Lead Time for Refractive Index - Single Crystal Germanium Wafer / Ingot – WMC

Zinc, grey-blue color transition metal, easily soluble in acid, and easily oxidation in room temperature and oxidize fiercely when heating to 225°C, is of good wear resistance, corrosion resistance, and anti-electromagnetic field performance.

High purity zinc of 99.999%, 99.9999% and 99.99999% 5N 6N 7N by zone-floating or crystal growth process is primarily used in the manufacturing of compound semiconductors such as Cadmium Zinc Telluride (CdZnTe), Zinc Sulfide ZnS, Zinc Selenide ZnSe etc, high purity alloys, reductant and in the application of precision casting in automobile industry etc. High Purity Zinc at Western Minmetals (SC) Corporation with 99.999%, 99.9999%, 99.99999% 5N 6N 7N purity is in size of shot, granule, ingot, bar and crystal or customized specification can be delivered, which is packed in composite aluminum bag with carton box outside.
