Nowadays, cars are running all over the streets, and people are no longer surprised, but some cars that are painted with metallic paint and glisten in the sun can always attract people's attention more. The important raw material for the metallic paint that gives these vehicles a wonderful luster is one of the new materials that the state encourages to develop—spherical aluminum powder.

Spherical aluminum powder is made by atomizing aluminum droplets or liquid strips into granules through inert high-pressure gas in the molten state, and its appearance is silver gray. At present, it is an important direction for the development of fine spherical aluminum powder to improve its weather resistance and oxidation resistance by modifying the fine spherical aluminum powder.

Micro-spherical aluminum powder has the advantages of regular shape, smooth surface, high active aluminum content, and stable product quality. has an important role. Some of its applications are as follows:

①Metallic aluminum powder pigment: the aluminum paste made of fine spherical aluminum powder after grinding has the characteristics of metallic feeling and good sparkle, high buoyancy and strong hiding power, and has good light and heat reflection performance, and is mainly used for the production of aluminum pigments .

② Solar aluminum paste: China has developed into the world's largest producer of solar cells, and solar aluminum paste is an emerging demand market for spherical aluminum powder. The solar aluminum paste industry has a large demand for aluminum powder, and the price is also high. The particle size of spherical aluminum powder generally requires d50≤10μm, and the amount of aluminum powder is also rising further.

③Military industry field: As a raw material for solid rocket fuel and high-explosive explosives, there is a certain demand for fine spherical aluminum powder every year. The military industry belongs to the national planned production. The amount of aluminum powder used is determined by the production volume of the manufacturer. It is currently on the rise, and the added value of this industry is relatively high.

④Refractory materials: The high specific surface area and high surface activity of fine spherical aluminum powder can be used in the preparation of refractory materials to promote sintering, binders, anti-oxidation, and improve performance.
