ZnO2【Density of zinc oxide】5.606g/cm^3(20℃)

Zinc oxide (ZnO), commonly known as zinc white, is an oxide of zinc. Hardly soluble in water, soluble in acid and strong alkali. Zinc oxide is a commonly used chemical additive, which is widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints, ointments, adhesives, food, batteries, flame retardants and other products. Zinc oxide has a large energy band gap and exciton binding energy, high transparency, and excellent room temperature luminescence performance. It is used in semiconductor liquid crystal displays, thin film transistors, light-emitting diodes and other products. In addition, micro-particle zinc oxide as a nano-material also began to play a role.

Zinc oxide is zinc oxide, hardly soluble in water, but soluble in acids and strong bases. It is a white solid, so it is also called zinc white. It can be obtained by burning zinc or roasting sphalerite (zinc sulfide). In nature, zinc oxide is the main component of the mineral Zincite. Although there are two manufacturing methods for man-made zinc oxide: it is made from pure zinc oxidation or roasted zinc ore. Zinc oxide is used as an additive in a variety of materials and products, including plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, interstitial materials, pigments, food (zinc supplements), batteries, ferrite Body materials, flame-retardant materials and medical emergency bandages, etc.
