Composite Ceramic BN-ZS, Boron Nitride-Silicon carbide-Zirconia Composite Ceramics

Composite Ceramic BN-ZS

Boron nitride-zirconia composite ceramics is a composite ceramic product that combines zirconium oxide (ZrO2) and boron nitride (BN) using the principle of composite performance superposition. Composite ceramic BN-ZS combines the excellent compressive strength, flexural strength, and wear resistance of zirconium oxide with the good thermal shock resistance and processing performance of boron nitride, and is a high-performance composite material.
