Introduction:
Different preparation methods and process conditions can produce nano-alumina with different structures: χ, β, eta and γ-type alumina, which are characterized by porosity, high dispersion and high activity, and are activated alumina; κ, δ, θ types Aluminum oxide; α-Al2O3 has a low specific surface and is inert with high temperature resistance, but it is not an activated alumina and has almost no catalytic activity; β-Al2O3 and γ-Al2O3 have a large specific surface, high porosity and heat resistance. Strong, good formability, strong surface acidity and certain surface alkalinity, it is widely used as new green chemical materials such as catalysts and catalyst carriers. The nano-alumina is in the state of white fluffy powder, and its crystal form is γ-Al2O3. The particle size is 20nm; the specific surface area is ≥230m2/g. Uniform particle size distribution, high purity, dispersion, high specific surface area, high temperature resistant inertness, high activity, is activated alumina; porosity; high hardness, good dimensional stability, can be widely used in various plastics, rubber, ceramics , Reinforcement and toughening of refractory materials and other products, especially improving the compactness, smoothness, cold and heat fatigue, fracture toughness, creep resistance and wear resistance of polymer material products, especially in solvent water; Solvents such as ethanol, glycol, ethylene glycol monobutyl ether, butanone, benzene, and xylene do not need to add dispersants, and can be fully dispersed evenly by stirring. In epoxy resin, plastic, etc.,
The diversity of alumina properties makes it widely used, but more than 90% is used to produce metallic aluminum, while the rest is used as fillers for plastics and other polymer products, adsorbents and catalysts, raw materials for pharmaceuticals, cosmetics, and chemical products, ceramics, abrasives, and refractory materials.
