–type alumina does not dissolve in water, but it can be dissolved in an acidic or alkali solution. G-type Alumina transforms into a type Alumina when heated to 1200°C. A porous, porous substance of several hundred square metres in surface area. It also has high activity and strong absorption capabilities. These cylindrical pinkish or colorless industrial products have good resistance to high pressure.
The particle size of g-phase nano-alumina is smaller than that of 20nm, with uniform particle size distribution, high purity, excellent dispersion, high specific surface, high temperature-resistant inertia and high activity, so it belongs to active alumina, porosity, high hardness and good dimensional stability.
You can use it to strengthen and toughen many types of materials, including rubber, plastics, ceramics, refractories, etc., particularly in increasing the hardness and finish of the polymer material, as well creep resistance and creep resistance. It’s easy to dissolve in solvent water. You can mix it with ethanol, propanol and propylene glycol or isopropanol as well as ethylene glycol monobutylether, acetones, butanones, benzene, and xylene. It’s often used in epoxy resins, plastics, and other materials.
