What is Spherical Al2O3 Powder?

How do you define it?

Spherical HTML2O3 Pulver

Aluminium oxide, an inorganic compound with the chemical name Al2O3, is an inorganic material. This high-hardness compound has a melting point at 2054 °C and boiling point at 2980 °C. It can be ionized at very high temperatures, and is commonly used for the production of refractory substances.

Alumina for industrial use is made from diaspore, bauxite (3H2O3) and Al2O3*3H2O3. Chemical methods are used to prepare Al2O3 for high purity. It is possible to find Al2O3 in many forms. More than 10 are currently known. The most common crystal forms of Al2O3 are a-Al2O3,-b-Al2O3, or g2O3. They all have different structures and different properties. At temperatures higher than 1300degC, it can be almost entirely converted into Al2O3.

High-temperature melt spraying produces spherical Alumina with high sphericity. This alumina has excellent performance as a filler in rubber, plastics, and ceramic raw material.

Here are some of the key features

Spherical Al2O3 powder

1. High filling density: This product is capable of high-density plastic and rubber filling.

2. High thermal conductivity. High filling densities enable the production of compounds with a greater thermal conductivity, and a lower heat dissipation than that produced from crystalline silicon.

3. Low abrasivity:

Its Spherical shape makes it less likely to wear forming machines or kneading machinery.

Spherical Al2O3 Powder, CAS 1344-228-1

Spherical Al2O3 Pulver is used in a variety of applications

1. This micropowder is used as a ceramic product. Spherical Micropowder’s good pressability and sintering capabilities make it an excellent choice for ceramic production.

2. It can be used as grinding material and polishing material.

3. This is used in the petrochemical sector. In the petrochemical sector, there are higher demands on the distribution and structure of the pores and the pore sizes. You can adjust the configuration of the particles to regulate the formation of catalyst carriers. Distribution and pore size.

4. This thermally conductive composite spherical aluminum powder is very thin and has good filling properties. You can use it to create artificial teeth and bone.
