For Catalysts
Flash calcined alumina /Transitional rho alumina powder with Chi Rho (χ ρ) crystal structure ((we may call it x-Rho Alumina(crystal), Flash calcined alumina(processing way) or Rehydratable Alumina V-R3 UOP (physical property) )is of easy dispersion and strong permeability, the product can be used as the inorganic coating of the substrate, material for adsorbent and catayst support, as well as for many other uses. Also, after dehydration and heat treatment, it can be converted from AlOOH (Al2O3 amorphous)→Gamma Al2O3 with large surface area and porous→Alpha Al2O3.
