Zirconia (ZrO2), specifically Yttria-Stabilized Tetragonal Zirconia Polycrystal (Y-TZP), is the "ceramic steel" of the engineering world. For bead mills, these parts include inner liners, rotors, pins, and discharge screens. The primary reason for choosing Zirconia Ceramic Parts for Bead Mill over alumina or hardened steel is their fracture toughness and extreme hardness.
At CRAC, we utilize ultra-fine zirconia powder to ensure a dense, non-porous microstructure. This prevents "micro-spalling"—the shedding of tiny ceramic particles into your slurry—which is critical for high-purity applications like semiconductor polishing and pharmaceutical milling.
