How does the thermal conductivity of 3 W/(m·K) affect the zirconia ceramic plate's performance in thermal barrier applications?
The plate's low thermal conductivity (3 W/(m·K)) makes it suitable as a thermal insulator in high-temperature environments up to 1600°C. This property, combined with a thermal expansion coefficient of 10×10⁻⁶/°C and thermal shock resistance of 350°C, ensures dimensional stability under rapid temperature changes.
What electrical insulation properties does the zirconia ceramic plate provide for high-voltage applications?
The plate offers excellent electrical insulation with volume resistivity greater than 1×10¹⁰ Ω·cm and dielectric breakdown strength of 15 kV/mm. At 1 MHz, its dielectric constant is 12.5, making it suitable for insulating components in electronic and high-voltage systems.
How does the sintering temperature of 1650°C influence the mechanical strength and density of the zirconia plate?
The plate is sintered at 1650°C, achieving a density of 5.9 g/cm³ and near-zero water absorption (0%). This high-temperature processing yields a hardness of 1400 HV, 4-point flexural strength greater than 11000 (units as specified), and compressive strength of 25,000 kgf/cm², ensuring robust mechanical performance.
The Atomfair Zirconia Ceramic Plate (AF-ZR-20X20W001) 20 mm x 20 mm x 1 mm is a high-purity (ZrO2 >= 94%) technical ceramic offering a maximum service temperature of 1600 °C, high hardness (1400 HV), and electrical insulation (volume resistivity > 1 x 10^10 Ω·cm), making it suitable for demanding high-temperature and corrosive lab environments.
Positive
- High thermal and mechanical stability: With a maximum service temperature of 1600 °C and thermal shock resistance of 350 °C, the plate maintains structural integrity under rapid thermal cycling, which is critical for furnace or high-temperature processing applications.
- Excellent electrical insulation properties: Volume resistivity above 1 x 10^10 Ω·cm and dielectric breakdown strength of 15 KT/m ensure reliable electrical isolation in high-voltage or sensitive instrumentation setups.
Trade-offs
- Low thermal conductivity limits heat dissipation: Thermal conductivity of 3 W/(m·K) may restrict use in applications requiring efficient heat transfer, potentially leading to localized hot spots if used as a substrate without additional thermal management.
- Brittle under tensile loading: Despite high compressive strength, the material's brittle nature and lack of ductility necessitate careful handling to avoid chipping or fracture during machining, mounting, or mechanical cycling.
