Chemical filling beads is an inert alumina ceramic ball. called "ceramic balls" because of their inner shape like ceramics sphere.

Inert ceramic ball does not participate in chemical reactions. It is calcined from alumina powder into industrial powder, and then calcined into dense structure at high temperature through rotary kiln and tunnel kiln. This dense and stable chemical structure looks like a ceramic, so it is called alumina ceramic ball. Different from general ceramics, alumina ceramics have a Mohs hardness of 9, second only to diamond, and its compression and impact resistance are far from ceramics. At the same time, it has the same advantages as ceramics: acid and alkali resistance, corrosion resistance. These good properties make inert alumina filler balls more and more widely used in industry.

At present, inert alumina ceramic balls are widely used in high-purity products, such as 90/92/95/99, which are widely used in chemical, petroleum and other industries. The materials required in these industries need to be resistant to corrosion by organic solvents such as strong acids and bases, resistant to high temperature and high pressure, and cannot participate in the reaction. These requirements are precisely that alumina filler balls can meet the needs, so they have attracted much attention.

In addition to high inert alumina balls, Chemshun Ceramics also provides other medium-aluminum, medium-high-aluminum, and low-aluminum chemical ceramic balls. Filler balls with these contents should have an advantage in price, but there will be a noticeable difference in content and ratio compared to high aluminum. Generally, the lower the content, the lower the ratio, and the worse the compressive strength and impact resistance. Therefore, customers should choose the appropriate content of alumina balls according to the actual industrial environment needs.
