How does the thermal shock resistance of 350°C affect the practical use of this zirconia plate at its maximum service temperature of 1600°C?
The thermal shock resistance of 350°C means the plate can withstand sudden temperature changes up to 350°C without cracking, but when operating near the maximum service temperature of 1600°C, careful heating and cooling rates are required to avoid exceeding this differential. The plate's low thermal conductivity of 3 W/(m·K) further necessitates gradual temperature ramps to prevent internal stresses.
What are the dielectric properties of this zirconia plate for use as an electrical insulator in high-temperature environments?
The plate offers excellent electrical insulation with a volume resistivity greater than 1×10¹⁴ Ω·cm and a dielectric breakdown strength of 15 KT/m. Its dielectric constant at 1 MHz is 12.5, making it suitable for high-frequency insulation applications up to 1600°C.
Why is the sintering temperature of 1650°C higher than the maximum service temperature of 1600°C?
The sintering temperature of 1650°C is required to achieve full densification (density 5.9 g/cm³) and zero water absorption, which are critical for the plate's mechanical strength and thermal stability. The maximum service temperature of 1600°C is set slightly lower to ensure long-term dimensional stability and prevent microstructural degradation during extended use.
This 50 mm x 50 mm x 2 mm black zirconia ceramic plate with ≥94% ZrO2 offers high hardness (1400 HV), compressive strength (25,000 kgf/cm²), and a maximum service temperature of 1600 °C, suitable for high-temperature electrical insulation and corrosion-resistant lab applications, though its low thermal conductivity (3 W/(m·K)) and thermal shock limit (350 °C) impose careful handling under rapid temperature changes.
Positive
- High thermal stability and insulation: Maximum service temperature of 1600 °C and volume resistivity above 1 × 10¹² Ω·cm enable operation in high-temperature electrical insulation environments without conductive failure.
- Exceptional mechanical strength: Hardness of 1400 HV, compressive strength of 25,000 kgf/cm², and 4-point flexural strength >11000 provide structural integrity under mechanical stress in demanding ceramic applications.
Trade-offs
- Low thermal conductivity: Thermal conductivity of 3 W/(m·K) limits heat dissipation, potentially causing localized thermal gradients that may affect adjacent components or require additional thermal management.
- Thermal shock sensitivity: Thermal shock resistance of 350 °C necessitates controlled heating and cooling rates to avoid fracture during rapid temperature transitions.
