Zinc Oxide Product Introduction

Basic properties of zinc oxide

Zinc oxide (ZnO), commonly known as zinc white, is a white solid that is difficult to dissolve in water but soluble in acids and strong bases. It has high chemical stability and is not easy to decompose at high temperatures. These properties make zinc oxide widely used in many fields

Specifications

Physical properties

Appearance and color: Zinc oxide usually appears as white to light yellow powder or hexagonal crystals, non-toxic, odorless and tasteless.

1. Solubility: It is insoluble in water and organic solvents, but soluble in acids and strong bases.

2. Crystal structure: The crystal structure of zinc oxide is diverse, the most common of which is the 3.hexagonal wurtzite structure, which gives zinc oxide excellent electrical, optical and piezoelectric properties.

4. Other physical properties: It has high refractive index, low dielectric constant, high transmittance and other characteristics.

Application areas

1. Rubber industry: As a vulcanizing agent and filler, it enhances the strength, elasticity and durability of rubber.

2. Cosmetics and personal care: Widely used in sunscreen, baby diaper rash cream and other products, with UV shielding and skin protection.

3. Pharmaceutical industry: Applied to skin care products, such as ointments and creams, with antibacterial and wound healing effects.

4. Ceramics and glass: Used to improve the thermal shock resistance and durability of ceramics and glass.

5. Electronic industry: As a semiconductor material, it is used in electronic components such as sensors and varistors.

6. Coatings and coatings: Improve the weather resistance, adhesion and UV protection of coatings, suitable for outdoor coatings.
