Hydratable alumina, or rho-alumina, is a specific form of alumina (aluminum oxide, Al₂O₃) that has unique properties compared to other alumina varieties.  Hydratable alumina has a specific crystalline structure, denoted as the rho (ρ) phase of alumina. This structure allows for the reversible incorporation of water molecules into the material. It means it can undergo reversible hydration and dehydration processes. Hydratable alumina has a porous structure with a network of interconnected pores and the pore size distribution can be tailored for specific applications. This material typically has a high specific surface area. These properties make rho-alumina an important and versatile material with a range of industrial and commercial applications. EAM provides hydratable alumina with different particle size distributions and specific surface areas According to the consumer’s request.
