Zinc Oxide Introduction
Zinc oxide (ZnO), commonly known as zinc white, is an oxide of zinc. It is insoluble in water, but soluble in acid and strong alkali. It is yellow at high temperature, turns white after cooling, and sublimates at 1800℃. The zinc oxide lattice is of ZnS type, oxygen is in the tetrahedron formed by zinc, and zinc is also in the tetrahedron of oxygen, and the coordination number is 4. It is a strong ultraviolet absorber and is used in industry as a reinforcing agent for rubber products, a white pigment, a plastic filler, a paint colorant, and as the main component of emollients, ointments, and zinc pastes.

Zinc Oxide Characteristics:
Appearance: Zinc oxide is a white powder with a fine particle structure and is commonly used in paints and pigments.
Solubility: Zinc oxide is nearly insoluble in water, but soluble in acids (such as hydrochloric acid) and bases (such as sodium hydroxide).
Optical Properties: Zinc oxide is a semiconductor with a wide bandgap (approximately 3.37 electron volts). It strongly absorbs UV light and is therefore widely used in sunscreens.
Thermal Stability: Zinc oxide has a high melting point (approximately 1975°C) and good thermal stability, making it suitable for use in high-temperature environments.
Electronic Applications: Due to its semiconductor properties, zinc oxide has important applications in optoelectronic devices, transparent electronic devices, and sensors.
Catalytic Properties: Zinc oxide can act as a catalyst in certain reactions, such as methanol synthesis.
These properties make zinc oxide widely used in electronics, coatings, pharmaceuticals, cosmetics, and other fields.
Zinc Oxide Advantages:
1. Superior Quality: Utilizes an advanced direct production process to ensure consistent quality and purity.
2. Versatility: Suitable for a variety of industries, including rubber, ceramics, and cosmetics.
3. Environmentally Friendly and Safe: Low in heavy metals, it is safe for a wide range of applications.
4. Excellent Performance: Provides enhanced reinforcement, thermal stability, and UV protection.
