Product Description

$refractory material direct manufacturer zinc oxide powder$ $refractory material direct manufacturer zinc oxide powder$ Zno is a kind of zinc oxide. Poorly soluble in water, soluble in acid and alkali. Zno is a kind of common chemical additives, widely used in plastic, Portland products, synthetic rubber, lubricating oil, paint coating, ointment, adhesives, food, battery, flame retardants, and other products.

Zinc oxide of the band gap and the exciton binding energy is larger, high transparency, has excellent luminescent properties under normal temperature, liquid crystal displays, in the field of semiconductor thin film transistor, light-emitting diodes, and other products are used.

In addition, the micro particles of zinc oxide as a kind of nano material are also beginning to play a role in the related field.
