A new technology that can significantly increase the production rate of nanoscale zinc oxide products was identified in August 2003 by the Guizhou Science and Technology Commission. Experts believe that this scientific and technological achievement has reached the domestic advanced level.
According to Xue Tao, deputy director of the Guizhou Institute of Metallurgical Engineering and the director of the Nanomaterials Engineering Center of Guizhou Province, who presided over the subject, nano-sized zinc oxide produced by this new technology can achieve a yield of more than 90%. Also relatively uniform, up to 10-30 nm, purity up to 99.7%, but the production cost can be greatly reduced. At present, the market price of 1 ton of nano-sized zinc oxide in the domestic market is about 250,000 yuan. Using this technology, the cost can be reduced by at least 60,000 to 70,000 yuan per ton.
It is understood that nano-ZnO is a new type of highly functional and highly functional inorganic material with a particle size of between 1 and 100 nanometers. The subtle size of the particles makes it produce surface effects, small size effects, quantum effects, and macroscopic quantum tunneling effects that are not found in the bulk materials of the bulk, thereby giving the traditional product of zinc oxide many new technologies in the field of science and technology. Its use, such as the use of its resistance change, can be made into a gas alarm; using its UV shielding ability, can be made into cosmetics sunscreen; using its semiconductor light-sensing theory, it can be used as a high-efficiency photocatalyst, used to degrade organic pollution in water. Things, clean the environment, etc.
