Adopting unique synthesis technology, it can simultaneously improve the purity, particle size, morphology, and crystal phase of alumina powder（ α Phase γ Control performance indicators such as phase content, and on this basis, dope modification and component control are carried out for different uses such as transparent ceramics, structural ceramics, and coating materials. At the same time, relying on a complete and first-class analysis and testing platform, strict quality control is carried out to ensure quality stability.

Lithium ion diaphragms are coated with ceramics: firstly, they can enhance the thermal stability of the diaphragm, improve its mechanical strength, and prevent the contraction of the diaphragm from causing significant positive and negative contact; Secondly, it can improve its puncture resistance and prevent short circuits caused by long-term cycling of lithium dendrites through the separator; Thirdly, the porosity of the ceramic coating is greater than that of the separator, which is beneficial for enhancing the liquid retention and wettability of the separator, thereby extending the battery cycle life.
