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
  • Collection, filtration and classification of ZnO powder
Chemical reaction: 2Zn + O₂ → 2ZnO
Packaging & Storage
  • Standard packaging: 25 kg bags or 1 MT jumbo bags (custom options available)
  • Store in dry, cool, ventilated area away from moisture and sunlight
Safety Precautions
  • Use protective equipment to avoid inhalation
  • Prevent contamination during handling
  • Follow local disposal regulations
  • Keep away from acidic substances
