ALTech offers zinc concentrate with a majority zinc base component. Preparation of zinc concentrate typically involves the removal of water from a zinc solution.
ALTech specializes in producing high purity Zinc Concentrate with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Zinc concentrate is similar to powder in that it is made up of minute, dry particles of pure substance.
Our standard Concentrate particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron).
ALTech produces different grades, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. We also produce Zinc as rod, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide.
