High-frequency ceramic abrasives for polishing stone abrasives are typically small cylindrical shapes, white in color, and reusable. High-frequency ceramics offer better polishing effects and greater wear resistance compared to high-alumina ceramics. High-frequency ceramics, also known as device ceramics, are used in electronic equipment for mounting, securing, and protecting components, serving as insulating supports for current-carrying conductors, and as substrates for various integrated circuits. They feature a low dielectric constant, low dielectric loss, high mechanical strength, as well as high dielectric strength, insulation resistance, and thermal conductivity. Commonly used high-frequency insulating ceramics include high-alumina ceramics and steatite ceramics. With the advancement of the electronics industry, they are widely applicable in sectors such as electronics, hardware, and machinery.
