ZrO2 Zirconia Ceramic Plate 10×10×2 mm Black ATOMFAIR®

The plate exhibits high hardness and compressive strength but is susceptible to thermal shock above 350 °C. Sintering at 1650 °C and low water absorption require controlled thermal processing to prevent cracking or delamination.

• Thermal Shock Sensitivity: Avoid rapid temperature changes exceeding 350 °C to prevent fracture due to thermal shock.
• High-Temperature Service Limit: Do not exceed a maximum service temperature of 1600 °C to maintain structural integrity and electrical insulation.
• Electrical Insulation Constraint: Maintain volume resistivity above 1 × 10¹⁰ Ω·cm by avoiding contamination or moisture absorption during handling.

Inspect the plate for cracks or chips before use to ensure structural integrity. Use controlled heating and cooling rates to avoid thermal shock during processing.

Required Equipment: Furnace with programmable temperature ramp, Clean tweezers or vacuum pickup tool, Calibrated thermocouple

1. Inspect the plate
   Inspect the zirconia ceramic plate visually for any cracks, chips, or surface defects before handling.
2. Clean the surface
   Wipe the plate with a lint-free cloth and isopropyl alcohol to remove any particulate contamination.
3. Preheat the furnace
   Set the furnace to a starting temperature of 200 °C with a ramp rate not exceeding 10 °C per minute.
4. Load the plate
   Place the plate onto a clean alumina setter using tweezers or a vacuum pickup tool to avoid direct contact.
5. Ramp to processing temperature
   Increase the furnace temperature at a controlled rate of 5 °C per minute until reaching the desired sintering or annealing temperature.
6. Cool gradually
   Cool the plate at a rate of 5 °C per minute to below 200 °C before removing from the furnace to prevent thermal shock.

This 10 mm x 10 mm x 2 mm black zirconia ceramic plate (≥94% ZrO₂) offers high hardness (1400 HV), high compressive strength (25,000 kgf/cm²), and a maximum service temperature of 1600 °C, making it suitable for demanding high-temperature and wear-resistant lab applications, though its low thermal conductivity (3 W/(m·K)) and thermal shock resistance (350 °C) impose careful thermal management.

Positive

• High-temperature and mechanical endurance: With a maximum service temperature of 1600 °C, hardness of 1400 HV, and compressive strength of 25,000 kgf/cm², this plate withstands extreme thermal and mechanical loads for demanding ceramic applications.
• Electrical insulation and corrosion resistance: Volume resistivity >1 × 10¹² Ω·cm and ZrO₂ content ≥94% provide excellent electrical insulation and corrosion resistance, suitable for inert environments and high-voltage setups.

Trade-offs

• Low thermal conductivity limits heat dissipation: With thermal conductivity of only 3 W/(m·K), this plate acts as a thermal insulator, which may cause localized heat buildup and requires careful thermal management in designs.
• Moderate thermal shock resistance: Thermal shock resistance is rated at 350 °C, meaning rapid temperature changes beyond this threshold may cause cracking, demanding controlled heating and cooling protocols.
