Zinc oxide,high purity - Introduction
High purity zinc oxide is a colorless or white powder substance, its chemical formula is ZnO. The following is the introduction of the nature, use, preparation method and safety information of high purity zinc oxide:
Nature:
1. High purity zinc oxide has high thermal stability and chemical resistance.
2. It is a good photoelectric material with semiconductor properties.
3. High purity zinc oxide is almost insoluble in water at room temperature, but soluble in acid and alkali.
Use:
1. High-purity zinc oxide is widely used in the rubber industry as a rubber reinforcing agent and accelerator.
2. It is also an important component in the manufacture of paints, pigments and dyes.
3. High purity zinc oxide is used as electronic devices, optical materials, surface coatings and catalysts.
Preparation Method:
High-purity zinc oxide can be prepared by the following methods:
1. Oxidation method: zinc metal reacts with oxygen at high temperature to generate zinc oxide. High-purity zinc oxide can be obtained by thermal decomposition of zinc carbonate or evaporation.
2. Chlorine oxidation method: zinc oxide raw materials containing chlorine compounds are used to convert zinc oxide through chlorine oxidation at high temperatures.
Safety Information:
1. High purity zinc oxide is a harmless substance, but may cause respiratory irritation when inhaling too much dust or powder.
2. Avoid contact with skin and eyes, if contact occurs, please rinse with water.
3. Wear appropriate protective equipment such as gloves, lenses and dust masks during operation.
4. Storage should avoid contact with acid, alkali and flammable substances to prevent reaction.
