Zirconia Ceramics Overview

Zirconia is a highly durable industrial ceramic known for its hardness, fracture toughness, and corrosion resistance, addressing the common brittleness of ceramics. Its unique crack propagation resistance and high thermal expansion make it ideal for bonding with metals like steel. Due to these unique properties, zirconia is sometimes referred to as "ceramic steel."
