Zirconium Oxide (LY301(ZrO2-Y2O3))
Zirconium oxide (LY301(ZrO2)) is an advanced ceramic material stabilized by doping with yttrium oxide (Y₂O₃). As a structural material, YSZ exhibits exceptional hardness (>12 GPa), flexural strength (>1 GPa), and outstanding thermal shock resistance, maintaining performance stability at temperatures exceeding 1650°C. It is widely used in critical components such as thermal barrier coatings (TBCs) for aircraft engines, high-temperature furnace linings, and electrolytes for solid oxide fuel cells (SOFCs). Additionally, its low thermal conductivity and high wear resistance make it ideal for precision bearings, cutting tools, and artificial joints, demonstrating irreplaceable durability advantages in extreme environments.
