Characteristics and Applications of High-Alumina Ceramic Balls
With a compressive strength exceeding 2000-5000N, their high hardness makes them impact- and wear-resistant in industrial production, extending their service life and reducing equipment maintenance costs.

They also possess excellent high-temperature resistance, maintaining stable physical and chemical properties in temperatures exceeding 1200°C, making them suitable for high-temperature industrial equipment. For example, in high-temperature operations such as ceramic firing and metallurgical smelting, high-alumina ceramic balls can serve as support materials, ensuring the stability of the equipment's internal structure without compromising product quality.
They also possess excellent corrosion resistance and good chemical stability in acidic and alkaline environments, ensuring the safe operation of chemical equipment.
Furthermore, high-alumina inert ceramic balls are chemically stable, making them suitable for industries with high purity requirements, such as food and pharmaceuticals. Some products feature a large surface area and strong adsorption properties, making them suitable for use as catalyst supports or in purification processes, improving reaction efficiency and product quality.
Applications
Chemical Industry: Widely used in petroleum refining, fertilizer production, and other industries, it supports catalysts in catalytic cracking units to improve reaction efficiency; adsorbs impurities in gas purification towers; and serves as an inert filler in reactors to optimize material flow.
Metallurgical Industry: Used in blast furnaces, hot blast furnaces, and other equipment to improve gas distribution uniformity and heat exchange efficiency; purifies molten metal and increases product purity; and serves as a lining for high-temperature kilns to extend equipment life.
Environmental Protection: Used as a biofilter in wastewater treatment to degrade pollutants; used to adsorb and catalyze harmful gases in exhaust gas treatment; and used to filter high-temperature flue gases in waste-to-energy projects.
Ceramics and Refractory Industry: Used as a ceramic grinding media in refractory preparation to improve raw material quality, enhance material performance, and increase service life.
Thermal Storage: Due to its high specific heat capacity, excellent thermal stability, and high-temperature resistance, high-alumina pellets are suitable for thermal storage ball combustion systems in gas-fired and non-gas-fired industrial furnaces. It is particularly suitable for the air separation industry's virtual heat heating furnaces, regenerative ladle roasting furnaces, air separation equipment heat storage devices, and the non-ferrous metal industry's regenerative smelting furnaces. It can also be used as a heat storage carrier in large forging plants' regenerative trolley furnaces, regenerative electric boilers, and regenerative incinerators.
