The advantages of zirconia ceramic products are mainly reflected in their physical and chemical properties, including high hardness, high toughness, high flexural strength, good wear resistance, insulation, corrosion resistance, self-lubrication, and excellent thermal insulation.
- High hardness and toughness: Zirconia ceramics has high hardness, density between 5.95-6.05g/cm3, and high fracture toughness, more than 8MPa·m1/2, which makes zirconia resistant to crack propagation and excellent wear resistance.
- High flexural strength: The flexural strength of zirconia ceramics is more than 1200Mpa, much higher than the 552Mpa of tempered glass, showing its excellent mechanical properties.
- Good wear resistance: the wear resistance of zirconia ceramics is 15 times that of alumina ceramics, and the friction coefficient is only 1/2 of that of alumina ceramics.
- Insulation and corrosion resistance: Zirconia ceramics has good insulation, can withstand high temperature and corrosive environment, and has good corrosion resistance, and can maintain stable performance under harsh conditions.
- Self-lubrication: Zirconia ceramics has self-lubrication, which can solve the problem of contamination and inconvenience caused by lubricating medium.
- Excellent thermal insulation: Zirconia ceramics has excellent thermal insulation properties, which is suitable for application scenarios that require good thermal insulation performance.
These advantages make yttrium stabilized zirconia powder have a wide range of applications in many fields, including but not limited to structural ceramic parts, functional ceramic parts, oxygen sensors, solid oxide fuel cells (SOFC), thermal barrier coatings, catalyst carriers, medical, health care, refractories, textiles, etc.
