Problems solved by technology

The sol-gel method and the microemulsion method are seriously polluted, and the obtained products have low purity and uncontrollable particle size; the hydrothermal method can obtain products with high purity, narrow particle size distribution, and controllable particle size, but the reaction process requires high temperature and high pressure. environment, higher requirements for equipment, and certain dangers in the production process
[0004] Although the above methods can prepare tin antimony oxide conductive nanomaterials, they still have the disadvantages of difficult control of hydrolysis rate and crystal shape, low yield, low purity and low conductivity.
