Product Description
Organic ZNO Zinc Oxide Powder Sunscreen Agent For Feed Additives OEM
White Powder Or Hexagonal Crystals Zinc Oxide Purity ≥99.9% Insoluble In Water
Basic Properties of Zinc Oxide
Zinc oxide (ZnO) is a white to light yellow powder, non-toxic and odorless, insoluble in water and organic solvents, but soluble in acids and strong bases. It has high thermal and chemical stability, with a melting point of about 1975°C and a boiling point of up to 2360°C. The crystal structure of zinc oxide is diverse, the most common of which is the hexagonal wurtzite structure, which gives zinc oxide excellent electrical, optical and piezoelectric properties.
Preparation Method of Zinc Oxide
There are many methods for preparing zinc oxide, mainly including:
- Direct method: Oxidation of metallic zinc, simple process but lower purity
- Indirect method (wet chemical method): Preparation through chemical reactions of zinc salt solutions, yielding high-purity products
- Physical method: Includes vapor deposition and sputtering methods, suitable for thin film or coating materials

Theory
Zinc oxide is an N-type semiconductor with excellent luminescent properties at room temperature. Its large energy band gap and exciton binding energy result in high transparency. UV absorption occurs when valence band electrons absorb UV energy and undergo transitions. UV scattering effectiveness relates to particle size, with nanoscale particles offering significant advantages.
