For procurement managers and R&D scientists in the chemical and materials industries, sourcing high-purity Zinc Oxide (ZnO) is a critical step in ensuring product quality and performance. As a leading manufacturer and supplier, we understand the importance of detailed product information and a reliable supply chain. This guide aims to equip you with the knowledge to make informed purchasing decisions for your ZnO requirements.

Understanding Zinc Oxide's Core Properties

Zinc Oxide (CAS No: 1314-13-2) is an inorganic compound renowned for its unique set of properties. It is a white powder, insoluble in water but soluble in acids and strong bases. Its wide band gap and high refractive index make it invaluable in numerous applications. Industrially, its key attributes include UV absorption, antibacterial activity, excellent thermal stability, and its role as a semiconductor. These characteristics drive its demand across diverse sectors.

Key Applications Driving Demand

  • Rubber Industry: ZnO is a vital activator in the sulfur vulcanization process, enhancing the durability, tensile strength, and heat resistance of rubber products. Manufacturers rely on consistent ZnO supply for optimal compounding.
  • Paints and Coatings: As a white pigment, ZnO provides opacity and whiteness. More importantly, it acts as a UV absorber, protecting coatings from degradation and improving their lifespan. It also offers anticorrosive properties.
  • Pharmaceuticals and Cosmetics: Its mild antiseptic, astringent, and UV-blocking properties make ZnO a staple in sunscreens, diaper rash creams, calamine lotions, and other dermatological preparations. Purity is paramount in these sensitive applications.
  • Electronics: ZnO's semiconductor properties are exploited in varistors, gas sensors, transparent conductive films for displays, and even in LEDs and transistors, paving the way for advanced electronic devices.
  • Ceramics: In the ceramic industry, ZnO acts as a fluxing agent, lowering the melting point of glazes and improving thermal shock resistance. It also influences the gloss and color of ceramic finishes.

What to Look for When Buying Zinc Oxide

When you are looking to buy Zinc Oxide, several factors are crucial for B2B procurement:

  • Purity: For most applications, especially in pharmaceuticals and electronics, a high ZnO content (e.g., >99.5%) is essential. Always check the product specifications for detailed impurity profiles.
  • Particle Size: The morphology and particle size distribution can significantly impact performance, particularly in applications like UV blocking and catalysis.
  • Production Method: Understanding whether it's produced via the French (indirect) or American (direct) process can sometimes indicate differences in purity and particle characteristics.
  • Supplier Reputation: Partnering with a reputable manufacturer and supplier ensures consistent quality, reliable delivery, and competitive pricing. Look for suppliers with established track records and certifications.
