3N High-purity Boehmite


3N High-purity Boehmite


Features:


■ High containment of ALOOH.


■ Appearance:White powder withe pure crystal shape and few foreign magnetic matters. Besides, with Stable electrical performance, the product owns low harmful ion content.


■ Excellent heat resistance.


■ The temperature of 1% weightless dehydration can reach above 380℃. Acting as lithium battery diaphragm coating and for additives in transparent ceramic, the product will improve the heat resistance and safety of the battery.


■ With a narrow size distribution, it has a uniform particle size distribution to ensure the porosity of the coating, and with no coarse particles scratch the film.
