What is γ& gamma;-Alumina? Alumina with & gamma;-kind crystal form is & gamma;-alumina. & gamma;-type alumina is insoluble in water and also can dissolve in solid acid or alkali service. When heated up to 1200 ℃, γ& gamma;-type alumina is entirely transformed into α& alpha;-kind alumina. & gamma;-kind alumina is a porous substance with an internal surface area of numerous hundred square meters per gram and high activity and solid adsorption capability. Industrial products are commonly colorless or pink cylindrical particles with good stress resistance.
γ& gamma;- Alumina Features The bit size of γ& gamma;-phase nano-alumina is smaller than that of 20nm, with consistent particle dimension distribution, high purity, outstanding dispersion, high certain surface, high temperature-resistant inertia as well as high activity, so it comes from energetic alumina, porosity, high hardness and excellent dimensional security.
It can be extensively utilized in the reinforcement as well as toughening of all kinds of plastics, rubber, ceramics, refractories as well as various other items, especially in enhancing the compactness, surface, cool and warm tiredness, crack durability, creep resistance and use resistance of polymer products. It is easy to spread in solvent water; it can be consistently spread in ethanol, propanol, propylene glycol, isopropanol, ethylene glycol monobutyl ether, acetone, butanone, benzene and also xylene without adding dispersant. It is commonly included in epoxy resin, plastics, etc What is
& gamma;-Alumina utilized for?
