Alumina Powder, Packaging Type : white

Product introduction:
activated alumina powder is also known as the rho - alumina powder, which is a alumina transition phase. its main crystal phase is p alumina base. P alumina is made by aluminum hydroxide through suspension roasting rapid dehydration and rapid cooling system. its specific surface area more than 200㎡g, so it has strong flexibility , water absorption performance, and certain hydration.
