Spherical Aluminum Oxide Produced by high-temperature melting spraying, the aluminum oxide has high sphericity with a high content of a phase. Aluminum oxide that is spherical performs better when used in rubber, ceramic, and plastic materials.

Spherical aluminum oxide properties

1. High Filling
Aluminum oxide is spherical and has a large particle size distribution. It can fill rubber with high density.

2. High thermal conductivity
A mixture with good heat dissipation and high thermal conductivity can be achieved by filling spherical Al2O3 with high density.

3. Low abrasion
Due to the spherical nature of spherical Aluminum Oxide, the abrasion caused by equipment like kneaders or molding machines can be greatly reduced. This will extend the service life.

Spherical aluminum oxide applications

1. Ceramic additives
A certain amount of Nano-spherical Aluminum Oxide Powder can effectively solve ceramics’ shortcomings due to their low temperature brittleness, and can be converted into low-temperature Plastic Spherical Aluminum Oxide Ceramics. Adding 5.0% of Nano-spherical Aluminium oxide Powder to the body of conventional ceramics can increase the toughness of this ceramic and lower the sintering temperatures of the ceramic.

2. Composite Materials
Nano-spherical Al2O3 Powder can not only synthesize composite ceramic materials that have special properties, but can also make artificial teeth or bones.

3. Surface protective coating
Spraying spherical aluminum oxide particles on metals, polymers, etc. can improve hardness, corrosion, wear resistance, and fire resistance. It can also be used to protect surfaces such as machinery and pipelines.

4. Optical Materials
Aluminum oxide powder, which is nano-sized and spherical in shape, has the ability to absorb light with wavelengths below 250nm. When spherical powders of aluminum oxide are added to rare earth pigments, they can absorb nano-ultraviolet light using the blue shift effect. It will not affect the brightness of the phosphor.

It is possible to combine rare-earth fluorescent materials with nano-spherical Aluminum oxide as the material for high-pressure sodium lamp. Not only will this reduce the cost, but it will also increase the lifespan of the luminous lamps.

5. Semiconductor materials
This nano-scale, spherical, aluminum oxide powder can be used to make temperature sensors that are extremely sensitive to moisture. It is also a good substrate for large-scale integrated devices.

6. Catalysts and their carriers
Al2O3 powder spheres have a large surface area and are covered with mismatch bonds. The sheet will have abundant pores with a porosity range of 30-40%. These can be converted into porous membrane filters. This produces catalysts and carriers that are several times more efficient than similar products.
