Introduction
23%-30% alumina inert ceramic ball, is a transitional type of structural ceramic filler that lies between the basic type of inert ceramic ball (17%-23% Al2O3) and the medium-high alumina inert ceramic ball (Al2O3≥30%). 23%-30% alumina inert ceramic balls are often used in devices with operating conditions slightly higher than those of the "normal type".
Compared to 17%-23% inert ceramic balls, 23%-30% alumina inert ceramic balls offer improved mechanical strength, wear resistance, and chemical stability, a denser pore structure, lower water absorption, and better long-term stability without significantly increasing cost. In engineering applications, they are particularly suitable as a "transitional support layer."
23%-30% alumina inert ceramic balls are widely used as supports and transition layers in adsorption and catalysis devices, and their strength and wear resistance are significantly superior to basic types. They have a high cost-performance ratio, with prices significantly lower than high-alumina ceramic balls. In certain occasions, 23%-30% ceramic balls can replace part of 30%-40% medium-alumina ceramic balls.
