[0002] Nano-alumina is an inorganic substance with the chemical formula Al2O3. Different preparation methods and process conditions can obtain nano-alumina with different structures. Among them, χ, β, η and γ-type alumina are characterized by porosity, high dispersion and high activity, and are active alumina; κ, δ, θ-type alumina; α-Al2O3 has a low specific surface area and is inert to high temperatures, but is not active alumina. Nano-alumina will contain a small amount of impurities during the production process. In order to improve the purity of nano-alumina, it is necessary to remove impurities. The way to remove impurities is to put the nano-alumina into a removal solution for chemical reaction.
