What is γ& gamma;-Alumina? Alumina with & gamma;-type crystal type is & gamma;-alumina. & gamma;-type alumina is insoluble in water and also can liquify in solid acid or alkali service. When heated up to 1200 ℃, γ& gamma;-type alumina is totally transformed right into α& alpha;-kind alumina. & gamma;-kind alumina is a porous substance with an internal area of several hundred square meters per gram as well as high activity and strong adsorption capacity. Commercial products are typically colorless or pink round bits with excellent pressure resistance.
γ& gamma;- Alumina Features The particle dimension of γ& gamma;-phase nano-alumina is smaller sized than that of 20nm, with uniform bit size circulation, high purity, superb diffusion, high specific surface area, high temperature-resistant inertia as well as high task, so it belongs to energetic alumina, porosity, high solidity and good dimensional stability.
It can be extensively made use of in the reinforcement as well as toughening of all sort of plastics, rubber, porcelains, refractories and also various other products, especially in enhancing the compactness, coating, cool and warm exhaustion, crack sturdiness, creep resistance and wear resistance of polymer products. It is simple to spread in solvent water; it can be consistently dispersed in ethanol, propanol, propylene glycol, isopropanol, ethylene glycol monobutyl ether, acetone, butanone, benzene and also xylene without adding dispersant. It is typically included in epoxy resin, plastics, etc What is
