Zirconium oxide ceramics are white, yellow or gray when containing impurities, and generally contain HfO 2, which is not easily separated. Pure ZrO2 has three crystal states under normal pressure. The production of Zirconia Ceramic Pin requires the preparation of high-purity, good dispersion properties, ultra-fine particles, narrow particle size distribution, zirconia ultrafine powder preparation methods, zirconia purification mainly chlorination and thermal decomposition, alkali metal Oxidative decomposition method, lime melting method, plasma arc method, precipitation method, colloid method, hydrolysis method, spray pyrolysis etc.
Feature:
- Use temperature up 1700°C
- High density
- High hardness
- Lower thermal conductivity
- Chemical inertness
- Resistance to molten melten metals
- Good wear resistance
- High fracture toughness
