Aluna-2302HC is a low specific surface alumina powder synthesized by vapor phase method. Due to its low specific surface, Aluna-2302HC has excellent dispersibility and can be used to prepare dispersions of various concentrations without settling for a long time. The positive charge on the surface of the powder also provides special application properties in many applications.
