Product Details

Alumina balls, also known as modern water-purifying activated alumina, are porous, highly dispersible solid materials and have the characteristics required for catalysts, and are therefore commonly used as catalysts in the chemical industry. The following is a brief introduction to the use and properties of alumina balls.

Alumina Ceramic Balls as Catalyst auxiliary agent are the most widely used support media in the world because of their excellent consistence and reliability. Products to these specifications are manufactured from very high quality chemical-porcelain clay materials, which has quite excellent stability, high mechanical strength and resistance to thermal shock, This makes them all ideal choice for support of all types of catalyst.

According to the physical properties of alumina, alumina can usually be divided into three types: sand, flour and intermediate. These three types of alumina have large differences in physical properties. The sand-like alumina has a small bulk density, a large specific surface area, a slightly smaller angle of repose, and a smaller amount of a-Al2O3, and the coarse particles are more and more uniform, and the strength is higher. Flour-like alumina has a large bulk density, a small specific surface area, contains a large amount of a-Al2O3, more fine particles, and poor strength. The physical properties of the intermediate alumina are somewhere in between.
