Rho Aumina Activated Alumina Fine Powder
Activated alumina powder (ρ- Al2O3)
Activated alumina powder is produced with the rapid dehydration technology on aluminium hydroxide . The general content of the main crystal phase with ρ- alumina is about 70-85% and the specific surface area is above 220 m2/g. Activated alumina powder has strong activity, water absorption performance and certain hydration activity, mainly used as the raw material of activated alumina ball, the binder for amorphous refractory castings and high-grade ceramic, raw material of catalyst carrier, etc. The main crystal phase is χ-ρ.
