1. About Zirconia
Unlike traditional ceramics that tend to be hard and brittle, Zirconia has high strength, wear resistance, and flexibility far beyond those of most other technical ceramics. Zirconia is a very strong technical ceramic with excellent properties in hardness and corrosion resistance, all without the typical property of ceramics brittleness. Its unique resistance to crack propagation and high thermal expansion make it an excellent material for joining ceramics with metals like steel. Due to Zirconia's properties it is sometimes referred to as the "Ceramic steel".
