Spherical Aluminum oxide Powder Properties And Applications

Aluminum oxide spherical Aluminum oxide a-phase produced by high-temperature melting spraying has high sphericity. It performs well as a ceramic raw material and a rubber filler.

Spherical aluminum oxide powder Properties

1. High Filling Aluminum oxide with a spherical shape and wide distribution of particle sizes is a good product. It can fill rubber with high density. The mixture will have low viscosity, good fluidity and low viscosity.

2. High thermal conductivity
A mixture with good heat dissipation and high thermal conductivity can be achieved by filling spherical silicon powder with aluminum oxide.

3. Low Wear
Aluminum oxide spherical is less abrasive than other types of aluminum oxide. This means that equipment such as kneaders or molding machines can last longer.

Spherical aluminum oxide powder Applications

1. Use as a ceramic material
Spherical Aluminum Oxide has good compression-molding and sintering qualities, which are extremely beneficial for producing high-quality ceramics.

2. It is used as a material for grinding and polishing
You can prevent scratches by using spherical Aluminum Oxide as a polishing agent.

3. It is used in the petrochemical industries
In the petrochemical industries, the requirements for the distribution of pore sizes and the structure of the aluminum carrier are increasing. To control the pore sizes and distributions of the catalyst carrier particles, it is possible to adjust the particle size configuration for the spherical powder.


4. Catalysts:
Aluminum oxide spheres can be used as catalysts to reduce abrasion. They also increase the lifespan of the catalysts, which will lower the production costs.

5. Surface protective coating
Spraying spherical aluminum powder on plastics, metals, etc. Surface protection for machinery, knives and chemical pipelines can be improved by using this powder.

6. For luminescent material
Aluminum oxide powder spherical has a high density which reduces the scattering and loss of light.

7. Electronics industry
The excellent properties of spherical aluminium oxide in terms electrical, mechanical and thermal properties make it widely used in semiconductor electronic packaging.

What is Spherical Al2O3 Powder?

What is it? Spherical HTMLO3 powder ? Aluminium oxide can be described as an inorganic compound with the chemical formula Al2O3. It is a high-hardness compound that has a melting temperature of 2054degC, and a boiling temperature of 2980degC. It is an ionized crystalline that can be easily ionized at high temperatures. This crystal is commonly used in the production of refractory materials.
Industrial alumina is made from bauxite, Al2O3*3H2O and diaspore. Chemical methods are used to prepare Al2O3 with high purity requirements. There are many Al2O3 isomorphs. More than 10 types are known. There are generally three crystal forms of Al2O3, which are a-Al2O3,-b-Al2O3, or g-Al2O3. They all have different structures and different properties. At temperatures over 1300degC, it can be almost entirely converted into a Al2O3.
The high-temperature melt spraying process produces spherical Alumina with high sphericity. This alumina has excellent performance as a filler for rubber, plastics, ceramic raw materials.
The key features of Powder Spherical al2O3
1. High filling density. This product is capable of filling rubber and plastics with high density.
2. High thermal conductivity. High filling density permits the production of compounds that have a higher thermal conductivity and a higher heat dissipation than crystalline silicona.
3. Low abrasivity:
Its Spherical shape makes it less likely to wear kneading, forming, and dies.

Spherical Al2O3 Pulver is used in a variety of applications
1. Spherical Micropowder can be used as a ceramic materials. It has excellent pressing and sintering characteristics, which is very beneficial in the production of high quality ceramic products.
2. It can be used as a grinding or polishing material.
3. This is used in the petrochemical and petroleum industries. There are increasing requirements for the pore size distributions and the pore structure of the carrier alumina. You can adjust the particle size configuration to control formed catalyst carrier particles. Distribution and pore size.
4. The thermally-conductive composite spherical aluminum powder has a limited thickening range and good filling performance. It can be used to make new composite materials with high thermal conductivity, such as thermally-conductive gaskets and thermally-conductive silicone grease, thermally-conductive potting (Glue), and thermallyconductive plastics. You can also use it to create artificial teeth or bones.
