Description

technical field

[0001] The invention relates to a preparation method of zinc oxide, in particular to a preparation method of ultrafine zinc oxide and zinc oxide whiskers. Background technique

[0002] Zinc oxide is a direct wide-bandgap semiconductor material with a wurtzite crystal structure. It has a variety of excellent physical properties and is widely used in rubber, ceramics, coatings, and optoelectronics. Ultrafine zinc oxide, due to its small particle size and large specific surface area, has surface effect, quantum size effect and Kubo effect, and exhibits many special properties, such as non-toxic and non-migratory, fluorescent, piezoelectric, absorption and scattering UV capability, etc. It has a wide range of uses in rubber, ceramics, daily chemicals, coatings, magnetic materials, etc., and zinc oxide whiskers are caused by their complete crystal structure, fewer internal defects, and their strength can be close to the theoretical value of complete crystal mater...
