Industrial Grade Zinc Oxide 99.8% for Rubber, Ceramic and TilesZinc oxide is an important raw material used for high-grade ceramics of ceramic chemical solvent. The glaze for tile and low-temperature glaze used in building ceramic wall & floor is large amount. It is is also widely used in the art glaze , in the ceramic industry, Zinc Oxide is widely used in brick and tile glaze and coarse pottery semitransparent glaze and process tableware transparent thick glaze or ripe glaze

Application1) Rubber industry: large surface area, more active, can be used as a vulcanization activator and other functional additives to improve the smoothness of rubber products, wear resistance, mechanical strength and anti-aging performance indicators and reduce the use of ordinary zinc oxide to extend the service life.
2) Ceramic industry: as opaque porcelain glaze and flux, can reduce the sintering temperature, improve the gloss and flexibility, has excellent performance.
3) Power electronics: nano-zinc oxide varistor nonlinear characteristics make it can play a role on over-voltage protection, anti-lightning, instantaneous pulse , become the most widely used varistor material.
4) National defense industry: nano-zinc oxide has a strong ability to absorb infrared, with large absorption and heat capacity ratio, can be applied to infrared detectors and infrared sensors; nano-zinc oxide also has a light weight, light color, strong absorption etc, can effectively absorb the radar wave and attenuation, applied to the new wave of stealth materials.
5)Textile industry: nano-zinc oxide with a good UV shielding and superior antibacterial properties, added into the fabric, can give the fabric to sunscreen, antibacterial, deodorant and other functions.
6) Feed industry: nano-zinc oxide as a nano-materials, with high efficiency biological activity, high absorption rate, strong antioxidant capacity, safety and stability characteristics, is the most ideal zinc source. In the feed with nano-zinc oxide instead of high zinc, both to solve the animal body on the demand for zinc, but also reduce the environmental pollution. The use of nano-zinc oxide can play the role of antibacterial and bacteriostatic, while improving animal production performance.
