Overview
Active Zinc Oxide (ZnO) is a specialized form of zinc oxide with enhanced reactivity due to its fine particle size and high surface area. It is produced through advanced processes like the French process or wet chemical synthesis, ensuring superior quality compared to standard ZnO. Widely recognized for its multifunctional properties, active ZnO is a critical additive in industries requiring high-performance materials. Its versatility stems from its ability to act as a catalyst, UV blocker, and reinforcing agent, making it indispensable in modern manufacturing.
Physical and Chemical Properties
Active ZnO exhibits a hexagonal crystal structure and appears as a white, odorless powder. Its high surface area (typically 30-50 m²/g) and small particle size (often below 100 nm) contribute to its exceptional reactivity. The compound is thermally stable up to 1975°C and insoluble in water but dissolves in acidic or alkaline solutions. Key chemical properties include its amphoteric nature, allowing it to react with both acids and bases. This reactivity is leveraged in applications like rubber vulcanization, where it accelerates cross-linking. Its UV absorption capability (blocking UVA and UVB rays) is another standout feature, exploited in sunscreens and protective coatings.
Main Applications
In the rubber industry, active ZnO serves as a vulcanization activator, improving tensile strength and elasticity. It reduces curing time and enhances product longevity, making it vital for tires, hoses, and seals. The ceramics sector uses it as a flux to lower melting temperatures and improve glaze durability. Coatings and paints benefit from its UV resistance and antibacterial properties, which prevent degradation and microbial growth. In pharmaceuticals, it is a key ingredient in ointments for its antiseptic and soothing effects. Additionally, active ZnO is a preferred material in sunscreen formulations due to its broad-spectrum UV protection and minimal whitening effect.
Safety and Storage
While zinc oxide is generally non-toxic, fine particles can pose inhalation risks, necessitating dust masks and proper ventilation during handling. Prolonged skin contact may cause mild irritation, warranting gloves and protective clothing. Storage requires a dry, cool environment to prevent moisture absorption, which can reduce reactivity. Bulk quantities should be kept in sealed containers away from acids, as reactions may release hazardous fumes. Spills should be contained and cleaned with inert materials like sand. Regulatory compliance (e.g., REACH, FDA) must be verified for specific applications, especially in food-contact or medical uses.
B2B Procurement Guide
When sourcing active ZnO, prioritize suppliers with ISO or GMP certifications to ensure consistent quality. Key specifications to confirm include purity (≥99%), particle size distribution (e.g., 20-100 nm for nano ZnO), and absence of heavy metals like lead and cadmium. Request technical datasheets and batch test reports to validate properties such as surface area and reactivity. Pricing varies with purity and order volume; bulk purchases (e.g., >1 ton) often attract discounts. Consider logistics—active ZnO is hygroscopic, so moisture-proof packaging and expedited shipping are advisable for international transactions.
