Product Description
Basic Properties of Zinc Oxide
Zinc oxide (ZnO) is a white to pale yellow, non-toxic and odorless powder. Insoluble in water and organic solvents, it can dissolve in acids and strong alkalis. Boasting outstanding thermal and chemical stability, it has a melting point of approximately 1975°C and a boiling point of 2360°C. Its typical hexagonal wurtzite crystal structure endows ZnO with superior electrical, optical and piezoelectric properties.
Preparation Method of Zinc Oxide
Multiple processes can be used to produce zinc oxide:
- Direct process: Oxidation of metallic zinc. It features a simple production route yet delivers relatively lower purity.
- Indirect process (wet chemical method): Synthesized via reactions of zinc salt solutions, yielding high-purity zinc oxide.
- Physical method: Vapor deposition and sputtering. Ideal for thin-film and coating applications.

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.
