Inert Alumina Ceramic Ball – High Purity Catalyst Support Media

Inert Alumina Ceramic Balls, also called ceramic balls, alumina ceramic balls, or inert ceramic balls, are widely used as catalyst support media and tower packing in industrial processes. They are made from high-purity alumina powder with low silicon content, providing excellent thermal stability, mechanical strength, and chemical resistance.

These inert alumina ceramic balls are ideal for petroleum, chemical, fertilizer, natural gas, and environmental protection industries. They serve as covering and supporting materials for catalysts in reactors, enhancing the distribution of gases and liquids in production systems and improving process efficiency.

The key properties of these alumina ceramic balls include high temperature and pressure resistance, low water absorption, and chemical stability. They can withstand the corrosion of acids, alkalis, and various organic solvents, and remain durable under thermal fluctuations during industrial operations.

Inert ceramic balls are also designed to protect catalysts from contamination and prevent leaching reactions in silica towers. They ensure that catalysts maintain their activity and longevity while providing support for various types of catalyst media.
