Description

Zinc CAS NO 7440-66-6 is a versatile, bluish-white metallic element essential for numerous industrial and chemical processes. Its primary value lies in its role as a powerful reducing agent, a vital alloying component, and a source of zinc ions for various compounds. This product is critical for industries including metallurgy for galvanizing and die-casting alloys, chemical manufacturing as a catalyst or precursor, and the pharmaceutical sector for nutritional supplements and ointments.

Application

• Galvanizing: As a sacrificial coating to protect iron and steel from corrosion.
• Die-Casting Alloys: A primary component in zinc-aluminum alloys (e.g., Zamak) for precision parts in automotive and hardware.
• Chemical Synthesis: Used as a reducing agent in organic chemistry and as a precursor for zinc salts like zinc oxide and zinc sulfate.
• Battery Technology: Anode material in zinc-carbon and zinc-air batteries.
• Pharmaceuticals & Nutrition: Source of essential zinc ions in dietary supplements and topical medicinal creams.
• Rubber & Paint Industry: As zinc oxide, a key additive for vulcanization and as a white pigment/UV stabilizer.
• Micronutrient in Agriculture: Incorporated into fertilizers to correct zinc deficiencies in crops.

Quality Control

Our zinc is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing assay and impurity profiles. Quality specifications can be aligned with various industrial standards, and we support customized purity grades upon request to meet specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its property of being easily oxidized, long-term storage is recommended under an inert atmosphere (e.g., argon or nitrogen) for maximum stability, especially for fine powders and dust.
