The plate must be handled with care to avoid thermal shock from rapid temperature changes exceeding 350°C. Electrical insulation properties are maintained only when the surface is free of conductive contaminants and the applied voltage gradient does not exceed 15 kV/mm.
- Thermal Shock Limit: Avoid subjecting the plate to temperature differentials greater than 350°C to prevent fracture.
- Maximum Service Temperature: Do not exceed 1600°C continuous operating temperature to avoid material degradation.
- Dielectric Breakdown: Ensure the applied electric field does not exceed 15 kV/mm to prevent insulation failure.
- Mechanical Loading: Point loads should not exceed the compressive strength of 25,000 kgf/cm² to avoid crushing.
- Surface Cleanliness: Keep the plate surface clean and dry to preserve electrical resistivity above 1×10¹⁴ Ω·cm.
How does the 1600 °C maximum service temperature and 350 °C thermal shock resistance affect the safe heating and cooling rates for this 2 mm zirconia ceramic plate?
The 1600 °C maximum service temperature combined with a thermal shock resistance of 350 °C means that rapid temperature changes exceeding 350 °C can induce fracture. For a 2 mm thick plate, engineers should ramp heating and cooling at a controlled rate to stay well within the 350 °C differential limit. The specified thermal conductivity of 3 W/(m·K) and thermal expansion coefficient of 10 × 10⁻⁶/°C further inform ramp-rate calculations to avoid thermal stress failure.
Can this 94% zirconia plate be used as a dielectric substrate or insulator in high-voltage or high-frequency lab setups?
Yes, it is suitable given its volume resistivity above 1 × 10¹⁴ Ω·cm, dielectric breakdown strength of 15 kV/mm (stated as KT/m, interpreted as kV/mm for this thickness), and dielectric constant of 12.5 at 1 MHz. The low water absorption of 0% ensures stable insulation even in humid environments. For high-frequency applications, the dielectric constant of 12.5 is a known value for 94% zirconia and must be factored into impedance matching.
What machining or handling precautions are required for this 150 mm × 150 mm × 2 mm plate given its high hardness of 1400 HV?
With a hardness of 1400 HV and 4-point flexural strength exceeding 11000 (units not stated but consistent with MPa or kgf/cm² level typical for zirconia), the plate is exceptionally hard and brittle. Diamond tooling is required for cutting or drilling, and drilling should be performed before final sintering. The self-lubricating property reduces friction but does not prevent brittle fracture; handling must avoid point loading or sharp impacts on the thin 2 mm cross-section.
The Atomfair Zirconia Ceramic Plate (150 mm x 150 mm x 2 mm, model AF-ZR-150X150W002) offers a high-density ZrO2 substrate with ≥94% purity, delivering electrical insulation, corrosion resistance, and thermal stability up to 1600 °C for demanding lab and process applications.
Positive
- High-temperature stability up to 1600 °C: A maximum service temperature of 1600 °C and sintering at 1650 °C enable use in high-temperature furnaces, kilns, and thermal barrier applications without dimensional degradation.
- Excellent electrical insulation properties: Volume resistivity greater than 1×10¹² Ω·cm and dielectric breakdown strength of 15 kV/mm provide reliable electrical isolation in high-voltage or sensitive instrumentation environments.
Trade-offs
- Brittle under mechanical shock: Despite high compressive strength (25,000 kgf/cm²) and hardness (1400 HV), zirconia ceramics are inherently brittle and can fracture under tensile or impact loads, requiring careful handling during installation.
- Limited thermal shock resistance at 350 °C: A thermal shock resistance of only 350 °C restricts rapid temperature cycling, as abrupt thermal gradients may induce cracking in the plate at higher differentials.
