Description
High purity alumina powder could be defined as 4N and 5N purity products. It can be used as membrane coating for lithium battery, transparent ceramics, high-purity alumina, functional ceramics and catalyst carrier, etc. Used for diaphragm coating, can improve the battery heat resistance and safety, uniform particle size, narrow distribution, ensure the porosity of the coating, no coarse particles scratch the film.
