The zirconia ceramic plate offers high-temperature stability and electrical insulation but has specific operational limits. Exceeding these limits may cause thermal shock, dielectric breakdown, or structural failure.
- Maximum Service Temperature: Do not expose the plate to temperatures exceeding 1600°C to prevent thermal degradation.
- Thermal Shock Resistance: Avoid rapid temperature changes greater than 350°C to prevent cracking from thermal shock.
- Dielectric Breakdown Strength: Do not apply voltages exceeding 15 kV per millimeter of plate thickness to avoid dielectric breakdown.
- Mechanical Load Limit: The plate can withstand compressive loads up to 25,000 kgf/cm²; avoid exceeding this limit to prevent fracture.
- Electrical Insulation: The plate provides electrical insulation with volume resistivity above 1×10^15 Ω·cm; avoid contamination with conductive materials that may reduce resistivity.
How does the high maximum service temperature of 1600 °C affect the thermal shock resistance of this zirconia ceramic plate?
The plate has a maximum service temperature of 1600 °C and a thermal shock resistance of 350 °C. While it can withstand continuous high temperatures, rapid temperature changes exceeding 350 °C may cause thermal stress failure. The thermal expansion coefficient of 10 × 10⁻⁶/°C and thermal conductivity of 3 W/(m·K) influence its ability to dissipate thermal gradients.
Is this zirconia ceramic plate suitable for electrical insulation applications requiring high dielectric strength?
Yes, with a volume resistivity above 1 × 10¹⁰ Ω·cm and a dielectric breakdown strength of 15 KT/m, the plate provides excellent electrical insulation. Its dielectric constant of 12.5 at 1 MHz indicates moderate capacitance, making it suitable for high-voltage environments where low leakage current is critical.
What infrastructure is required to machine or cut this zirconia ceramic plate given its hardness of 1400 HV?
The plate's hardness of 1400 HV requires diamond tooling for cutting or machining; standard carbide tools will wear rapidly. Additionally, the material's high compressive strength of 25,000 kgf/cm² and low water absorption of 0% mean that water-cooled cutting is acceptable without risk of moisture absorption, but care must be taken to avoid thermal shock from localized heating.
This 50 mm x 50 mm x 0.5 mm zirconia ceramic plate offers a ZrO2 content of at least 94%, providing a combination of high hardness (1400 HV), high compressive strength (25,000 kgf/cm²), and electrical insulation (volume resistivity >1 × 10¹² Ω·cm) for demanding laboratory applications requiring dimensional stability and thermal resistance up to 1600 °C.
Positive
- High-temperature stability up to 1600 °C: With a maximum service temperature of 1600 °C and a sintering temperature of 1650 °C, this plate maintains structural integrity under extreme thermal conditions, suitable for high-temperature furnaces or thermal processing.
- Excellent electrical insulation: Volume resistivity above 1 × 10¹² Ω·cm and dielectric breakdown strength of 15 KT/m provide reliable electrical isolation in high-voltage or sensitive electronic measurement setups.
Trade-offs
- Limited thermal conductivity: Thermal conductivity of 3 W/(m·K) is low compared to metals or some advanced ceramics, which can restrict heat dissipation in applications requiring rapid thermal transfer.
- Brittle failure risk under shock: Thermal shock resistance of 350 °C indicates susceptibility to cracking under rapid temperature changes, requiring controlled heating and cooling rates to prevent mechanical failure.
