Market Application Prospect Of Alumina Ceramics
Market application prospect of alumina ceramics
Alumina ceramics are widely used in the field of lithium battery membrane coating and catalyst carrier because of their excellent physical and chemical properties.
(1) The downstream demand of high purity ultrafine alumina is strong
The main function of lithium ion battery diaphragm is to separate the positive and negative electrodes of the battery to prevent short circuit. Its performance directly affects the capacity and safety of the battery.In the process of using the battery, the temperature is too high will make the diaphragm melt and cause a short circuit, coating on the diaphragm can improve the high temperature resistance of the battery, high purity ultra-fine alumina has good insulation, high temperature resistance and other characteristics, is a high-quality diaphragm coating material.
(2) With the increasingly prominent environmental problems, the market space for automotive catalysts is huge
The catalyst carrier of automobile exhaust is honeycomb cordierite ceramic coated with alumina and alumina doped with rare earth elements.Due to the poisonous carbon monoxide, nitrogen oxides and hydrocarbons contained in the automobile exhaust gas, the general gasoline engine cars are installed with automobile exhaust treatment device.Alumina ceramics are widely used in the field of catalyst support because of their excellent physical and chemical properties.With the outbreak of new energy industry, especially new energy vehicles, alumina ceramic materials will play a great role in the field of new energy by virtue of their excellent physical and chemical properties
