How do you define it?

Spherical HTMLO3 powder

Aluminium oxide, an inorganic compound with the chemical name Al2O3, is known as. This high-hardness compound has a melting point at 2054degC as well as a boiling point at 2980degC. 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 bauxite (3H2O*) and diaspore. 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, ceramics, etc.

Here are some of the key features

Spherical Powder of Al2O3

1. High filling densities: This product is capable of high-density plastic filling thanks to its large particles and wide distribution.

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, dies, and kneading equipment.

Spherical Al2O3 Powder, CAS 1344-281

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 a polishing and grinding material.

3. This is used in the petrochemical and petroleum industries. There are increasing requirements for the distribution of pore size and the structure and composition of the alumina carriers. You can adjust the size 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.
