The plate exhibits high hardness and compressive strength but is susceptible to thermal shock at temperature gradients exceeding 350 °C. Sintering at 1650 °C and low water absorption require controlled atmosphere processing to prevent contamination or cracking.
- Thermal Shock Sensitivity: Thermal shock resistance is limited to 350 °C, requiring gradual heating and cooling to avoid fracture.
- Sintering Requirement: The material is sintered at 1650 °C, necessitating high-temperature furnace capability for any post-processing or re-sintering steps.
- Electrical Insulation Constraint: Volume resistivity above 1 × 10¹⁴ Ω·cm and dielectric breakdown strength of 15 kV/mm require clean, dry handling to maintain insulation properties.
Inspect the plate for cracks or chips before use, as high hardness makes it brittle under impact. Use gradual thermal ramping to avoid exceeding the 350 °C thermal shock limit during heating or cooling.
Required Equipment: High-temperature furnace capable of 1650 °C, Diamond-tipped cutting or grinding tool, Clean, dry handling gloves
- Inspect the plate
Inspect the zirconia ceramic plate visually for any cracks, chips, or surface defects before processing. - Clean the surface
Clean the plate with a lint-free cloth and isopropyl alcohol to remove any dust or contaminants. - Set thermal ramp rate
Set the furnace ramp rate to no more than 10 °C per minute to stay within the 350 °C thermal shock resistance limit. - Heat to sintering temperature
Heat the plate to the required processing temperature, not exceeding 1650 °C, and hold for the specified dwell time. - Cool gradually
Cool the plate at a controlled rate of no more than 10 °C per minute to prevent thermal shock cracking.
How does the maximum service temperature of 1600°C relate to the thermal shock resistance of 350°C for this zirconia ceramic plate?
The plate can operate continuously up to 1600°C but must be heated or cooled slowly to avoid thermal gradients exceeding 350°C, which could cause fracture. This limitation arises from its thermal expansion coefficient of 10×10⁻⁶/°C and thermal conductivity of 3 W/(m·K), as specified in the product data.
Is this zirconia ceramic plate suitable for high-voltage electrical insulation applications?
Yes, with a volume resistivity above 1×10¹⁰ Ω·cm and dielectric breakdown strength of 15 KT/m, the plate provides excellent electrical insulation. However, verify that the applied voltage does not exceed the dielectric breakdown strength at the intended operating temperature.
What precautions are needed when machining or handling this zirconia plate due to its hardness?
With a hardness of 1400 HV and compressive strength of 25,000 kgf/cm², the plate is extremely hard and brittle. Use diamond tooling for cutting or drilling, avoid impact loads, and control thermal gradients to stay within the 350°C thermal shock resistance limit to prevent cracking.
The Atomfair AF-ZR-100X100W005 zirconia ceramic plate offers a 94% ZrO2 composition with a maximum service temperature of 1600 °C, high hardness (1400 HV), compressive strength of 25,000 kgf/cm², and electrical volume resistivity above 1 × 10¹² Ω·cm, making it suitable for demanding insulation and high-temperature applications.
Positive
- High-temperature stability up to 1600 °C: With a maximum service temperature of 1600 °C and sintering at 1650 °C, the plate maintains structural integrity in extreme thermal environments suitable for furnace linings or high-temperature fixtures.
- Electrical insulation with high resistivity: Volume resistivity exceeds 1 × 10¹² Ω·cm and dielectric breakdown strength is 15 KT/m, providing reliable electrical insulation for laboratory setups requiring isolation in high-voltage or high-temperature conditions.
Trade-offs
- Low thermal conductivity limits heat dissipation: Thermal conductivity is 3 W/(m·K); the plate does not effectively spread or dissipate heat, which may require careful thermal management in applications where rapid heat transfer is needed.
- Brittleness under mechanical shock: High hardness (1400 HV) and compressive strength (25,000 kgf/cm²) improve wear resistance, but flexural strength >11000 units and thermal shock resistance of only 350 °C indicate susceptibility to cracking under sudden thermal or mechanical stress, requiring slow heating and careful handling.
