Blue zirconia is a zirconia ceramic material prepared by a specific process, showing a unique blue appearance. Its preparation method usually involves adding specific colorants (such as metal oxides such as cobalt and nickel) to the zirconia matrix and achieving stable color presentation through a controlled sintering process. Blue zirconia not only retains the excellent properties of zirconia itself, but also has higher added value and application potential due to its unique color.
Performance advantages of blue zirconia
1. High hardness and high strength: Blue zirconia has extremely high hardness and strength, with a Mohs hardness of about 8.5, close to the hardness of sapphire, making it excellent in wear resistance and impact resistance.
2. High temperature resistance: Blue zirconia has excellent high temperature resistance and can maintain stable physical and chemical properties under high temperature environment. For example, the conductivity and color of some blue cubic zirconia crystals remain stable at 800-1000°C.
3. Corrosion and oxidation resistance: Blue zirconia has good corrosion resistance to chemicals such as acids and alkalis, and has excellent oxidation resistance, making it suitable for various harsh environments.
4. Insulation performance: Blue zirconia has good insulation performance and is suitable for electronic devices and high-voltage equipment.
5. Self-lubrication: The surface of blue zirconia has a certain self-lubrication, which can reduce friction and wear and extend service life.
6. High density and easy to clean: Blue zirconia has high density, dust is not easy to accumulate on the surface, and it is easier to clean and maintain.
