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, ceramics and plastics.

Spherical aluminum oxide properties

1. High filling
Aluminum oxide is a spherical powder with a large particle size range. 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 aluminium oxide, the abrasion caused by equipment such as kneaders or molding machines, and molds can be greatly reduced. This prolongs the life expectancy of the equipment.

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 be used for the manufacture of new composite ceramic materials that have special properties. It can also be made into artificial teeth or bones.

3. Surface protective coating
Spraying spherical aluminum oxide particles on metals, polymers, etc. can improve hardness, wear resistance, fire resistance and corrosion 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 doped in rare earths phosphors the nano-ultraviolet phenomenon, which is characterized by a blue shift, can be used to absorb this light. 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 luminescent component of luminous lamps. Not only will this reduce the cost, but it will also increase the lifespan of the lamp. In the future, this will be the primary fluorescent material used in the production of the lamp.

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

6. Catalysts and their carriers
Al2O3 powder spheres have a large surface area and are covered with mismatch and low-oxygen bonds. The sheet will have abundant pores with a porosity range of 30-40%. These can be converted into porous membrane filters. The catalyst and carrier produced by this method are several times better than similar products that are currently being used.
