Inert ceramic balls, also known as inert alumina ceramic balls, are widely used in industries such as petroleum refining, chemical engineering, fertilizers, natural gas, and environmental protection due to their stable molecular structure. They serve as catalytic support materials inside reactors. These balls are characterized by their ability to withstand high temperatures and pressures, low water absorption, and stable chemical properties. They are resistant to corrosion from acids, alkalis, and other organic solvents, and can endure the high-temperature fluctuations that occur during production processes. Their primary function is to increase the distribution points of gases or liquids, as well as to support and protect active catalysts with lower mechanical strength.
