one α- Aluminum oxide, also known as nano aluminum oxide, exhibits a white fluffy powder state with a crystal form of xz-L14 α Type. The particle size is 20nm; Specific surface area ≥ 50m/g. Uniform particle size distribution, high purity and high dispersion. It has low specific surface area and high temperature resistant inertia, but it does not belong to Activated alumina and has almost no catalytic activity.
2. Nano alumina xz-L14 has strong heat resistance, good formability, stable crystal phase, high hardness, and good dimensional stability. It can be widely used for reinforcing and toughening various plastics, rubber, ceramics, refractories and other products, especially to improve the compactness, smoothness, cold and hot fatigue, fracture toughness, creep resistance, and wear resistance of polymer products.
3. Due to α Phase alumina is also an excellent far-infrared emission material, used as a far-infrared emission and insulation material in chemical fiber products and high-pressure sodium lamps.
In addition, α Phase alumina has high resistivity and good insulation performance, which can be applied to the main accessories of YGA laser crystals and integrated circuit substrates.
four γ- Aluminum oxide, this γ- Alumina is a nano alumina xz-L290 in a white fluffy powder state, with a crystal form of γ- Al2O3。 The particle size is 20nm; Specific surface area ≥ 230m2/g.
5. Nano alumina xz-L290, with uniform particle size distribution, high purity, excellent dispersion, high specific surface, high temperature resistance, inertia and high activity, belongs to Activated alumina; porosity; With high hardness and good dimensional stability, it can be widely used for reinforcing and toughening various plastics, rubber, ceramics, refractories and other products, especially for improving the compactness, smoothness, cold and hot fatigue, fracture toughness, creep resistance and wear resistance of polymer products.
6. Excellent dispersion, in solvent water; Solvent ethanol, propanol, propylene glycol, isopropanol, ethylene glycol monobutyl ether, acetone, butanone, benzene, xylene, without the need for dispersants, can be fully dispersed and evenly stirred. Excellent addition and use in epoxy resins, plastics, etc.
