Key Features
- Extremely high purity (≥99.99%) for demanding applications
- Excellent optical properties with good UV transmittance
- Semiconductor characteristics for electronic devices
- High chemical and thermal stability
- Low impurity content for consistent performance
Chemical Properties
Zinc oxide demonstrates high chemical stability in harsh environments including high temperature, pressure, and exposure to strong acids/alkalis. As an amphoteric oxide, it reacts with both acids and bases. It also exhibits catalytic activity for various chemical reactions.
Product Advantages
- Superior Quality: Manufactured using direct-method technology for consistent purity
- Versatility: Suitable for rubber, ceramics, cosmetics and more
- Environmental Safety: Low heavy metal content
- Performance: Enhanced reinforcement, thermal stability and UV protection
Applications
Rubber Industry: Reinforcing agent, activator, and vulcanization accelerator
Ceramics: Improves whiteness, strength and thermal stability
Paints & Coatings: Pigment and anti-corrosion agent
Cosmetics: UV absorber in sunscreens and skincare
Pharmaceuticals: Antiseptic and astringent in ointments
Agriculture: Micronutrient in fertilizers and feed additives
Production Technology
The direct method (French process) involves:
- Selection of high-purity zinc materials
- Smelting and vaporization of zinc
- Oxidation of zinc vapor in controlled environment
