What is γ-Alumina?

What’s the definition of gAlumina? gAlumina In a gtype crystal form, it is known as galumina. Type alumina doesn’t dissolve in water. However, it may dissolve in acidic oralkali solutions. At 1200 degrees Celsius, the G-type Alumina will transform into type Alumina. G-type Alumina, which is porous and has high surface areas, shows strong adsorption properties. High pressure is not an issue for these cylindrical products, which are pinkish in color or completely white.

gAlumina Properties

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.

This can be used for strengthening and toughening many kinds of materials such as rubber, plastics, and ceramics. It is easy to dissolve in solvent. Mix it with propanol, ethanol and propyleneglol or isopropanol. You also have the option to mix it in solvent water, acetone, and ethylene glycol monobutylether. It is used often in epoxy resins, plastics, as well other materials.

What’s g-Alumina for?

Coatings: Plasma spraying, porcelain films coatings, wear-resistant coatings.

Ceramics: Bioceramics. Translucent ceramics. Alumina clays.

Petroleum industry uses catalysts, catalyst carrier and automobile exhaust purification materials.

Polishing materials: grinding single-crystalline silicon wafers and polishing submicron / micron materials.

Lighting: Low pressure sodium transparent tube with long afterglow.

Electronics: One crystal and integrated circuit substrates. Far-infrared materials and single crystal materials.
