20 nanometer alumina powder is an inorganic substance, the chemical formula is Al₂O₃, the powder material also has a high surface area, high porosity

Characterized by diameter distribution and high purity, the following are some of the main application areas of 20 nm alumina powder:

1, catalyst and catalyst carrier: 20 nanometer alumina powder because of its high specific surface area and good chemical stability, often used

Used as catalyst or catalyst carrier. In chemical reactions, it can provide a large number of active sites, promote the reaction,

Improve reaction efficiency and selectivity.

2, ceramic materials: alumina ceramics are known for their high hardness, high wear resistance and good chemical stability. 20 nm oxygen

Aluminum powder as raw material, can be prepared more excellent performance of nano-ceramic materials, these materials in wear resistance, high temperature resistance

And corrosion resistance has excellent performance, so it is widely used in aerospace, machinery manufacturing and other fields.

3, electronic materials: In the field of microelectronics, 20 nanometer alumina powder can be used to prepare highly integrated electronic devices. On account of

Nanometer size effect, alumina powder can be filled in the tiny structure of the device, improve the performance and reliability of the device. นอกจากนี้

Alumina also has good insulation properties and can be used to prepare high-performance insulating materials.

4, composite reinforcement phase: alumina powder as a reinforcement phase of composite materials, can significantly improve the mechanical properties of composite materials

Energy and wear resistance. For example, adding 20 nanometer alumina powder to a metal matrix composite can improve the composite

The hardness and strength, while maintaining its good processing properties.

5, polishing material: 20 nanometer alumina powder is often used as polishing material because of its high hardness and uniform particle size. In optics

In the fields of semiconductor and precision machinery, alumina powder can effectively remove small defects on the surface of the workpiece and improve the performance of the workpiece

Finish and precision.

6, coating material: alumina coating has good wear resistance, corrosion resistance and high temperature resistance. 20 nanometer alumina powder can

To prepare high-performance coating materials, used to protect the substrate from environmental erosion, extend the service life.
