Zirconia Ceramic Blocks and High-Temperature Ceramic Pad Blocks Product Introduction:
Zirconia ceramic is a high-performance ceramic material primarily composed of zirconium dioxide (ZrO₂), which is usually white at room temperature and contains trace amounts of hafnium dioxide (HfO₂) and the stabilizer yttrium oxide (Y₂O₃). Its characteristics include:
Ⅰ. Product Characteristics
1. High melting point: 2715℃.
2. High hardness: Vickers hardness HV1250.
3. Excellent wear resistance and toughness.
4. Phase transformation toughening is achieved through crystal structure transformation (monoclinic phase, tetragonal phase, cubic phase).
Ⅱ. Main Applications
1. Electrical Equipment:
Insulation for electrical components such as thermal protectors and terminal blocks.
Heat transfer and electrical isolation between power devices and heat sinks.
2. High-Temperature Industrial Applications:
Furnace temperature control systems.
High-temperature testing equipment.
Protection of industrial pipeline interfaces.
3. Precision Machinery:
Fixing and positioning in instruments and equipment.
Ensuring precise fitting of mechanical components.
