What exactly is g – Alumina? In a g type crystal form, g – Alumina Is this g -alumina?
–type alumina does not dissolve in water, but it can be dissolved in an acidic or alkali solution. When heated to 1200°C, g-type aluminum is transformed into a type alumina. G-type Alumina is porous with a high level of activity and a very strong adsorption ability. It has an internal surface area that can cover several hundred meters. These cylindrical pinkish or colorless industrial products have good resistance to high pressure.

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.
You can use it to strengthen and toughen many types of materials, including rubber, plastics, ceramics, refractories, etc., particularly in the improvement of the compressness, finish and fracture toughness of polymers. 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, acetone and butanone. It’s often used in epoxy resin, plastics, and other materials.

What does g-Alumina do?
Coatings: Wear-resistant coatings, porcelain film coatings, and plasma spraying.
Ceramics: Bioceramics, translucent ceramics, and alumina clays.
The petrochemical industry has catalysts, catalyst carriers and automotive exhaust purification materials.
