The comparison between open-pore and standard ceramic balls is primarily evident in three domains: their appearance, performance, and application outcomes.

The open-pore ceramic balls is distinguished by its visible holes, in contrast to the smooth surface of the standard ceramic ball, which lacks such openings. These apertures enhance the filtration and separation processes by offering an increased surface area, thus improving the efficiency of these operations. Open-pore ceramic balls typically feature pore sizes ranging from 2 to 200 nanometers, with a common range of 10 to 100 nanometers. With a porosity exceeding 30% and a surface area often reaching 100 to 1000 square meters per gram, these structural attributes ensure that the open-pore ceramic ball excels in adsorption, separation, and catalysis. In terms of performance, the open-pore ceramic ball exhibits superior permeability, making it suitable for filtering and separating impurities from liquids and gases. The standard ceramic ball, on the other hand, serves a more basic support function. Regarding application outcomes, open-pore ceramic balls are valued for their use in the petrochemical industry as fillers, particularly with calcined industrial alumina and high-quality kaolin from Suzhou, which boasts up to 80% acicular mullite content. These balls are characterized by their high-temperature resistance, thermal shock resistance, and robust mechanical strength. A small amount of modifier allows for the formation of buffer pores, resulting in a product that possesses exceptional mechanical strength and resistance to rapid cooling and heating.
