Zirconia ceramics, hailed as "ceramic steel," are an important member of advanced ceramic materials. Compared to ordinary ceramics, zirconia's greatest advantage lies in its high strength and high toughness.
Zirconium oxide ceramics possess excellent flexural strength and fracture toughness, with mechanical properties far exceeding those of alumina ceramics. They are less prone to brittle fracture under impact, making them particularly suitable for manufacturing structural components under high loads and high impact conditions.
Furthermore, zirconia ceramics exhibit outstanding wear resistance, high surface smoothness, and a low coefficient of friction. In mechanical transmission systems, zirconia bearings and bushings effectively reduce wear and extend equipment lifespan. Simultaneously, their excellent biocompatibility makes them widely used in medical fields such as artificial teeth and medical implants.
In the electronics industry, zirconia ceramics are valued for their insulation and dimensional stability. In recent years, with the development of smart wearable devices, zirconia ceramics have also been used in high-end consumer electronics products such as mobile phone back panels and smartwatch casings.
