Zirconia Ceramic Sheets Properties

 

Property Pure Zirconia (Monoclinic) - Unstabilized Yttria-Stabilized Zirconia (YSZ) Magnesia-stabilized zirconia (Mg-PSZ)
Typical Purity High-purity raw material, but unstabilized for the final product High purity High purity
Crystal Phases (at RT) Monoclinic (stable up to ~1170°C); Tetragonal and Cubic at higher temperatures. Primarily, Metastable Tetragonal can have a Cubic phase. Partially stabilized with tetragonal precipitates in a cubic matrix.
Density (g/cm³) 5.65–6.05 5.85-6.1 ~5.7
Melting Point (°C) ~2700-2715 Very High (similar to pure zirconia, but phase stability is key) Very High
Thermal Conductivity (W/m·K) Low (approx. 2-3) Low (approx. 2.5-3) Low (approx. 3)
Thermal Expansion Coefficient (10⁻⁶/K) ~10 9.5-10 10
Flexural Strength (MPa) Poor (due to phase transformation and brittleness) Up to 1000, 710-900 500
Compressive Strength (MPa) Not typically used structurally ~2000 ~2500
Fracture Toughness (MPa·m^0.5) Low (inherently brittle) Up to 10 (exceptionally high for ceramics due to transformation toughening), 8-9 6
Hardness (Vickers, HV1) Moderate 11-13 GPa, 1100-1220 kg/mm² 1100 kg/mm²
Chemical Inertness Excellent in acids and alkalis Excellent Excellent
Biocompatibility Generally good, but stabilized forms are preferred for medical use Excellent, widely used in dental and medical implants Good
Typical Applications Refractories (at high temperatures) Structural ceramics, dental implants, oxygen sensors, cutting tools, thermal barrier coatings Refractories, structural components requiring specific thermal properties

ZrO2 Ceramic Sheet Applications

  • Laser Welding Workstations: used underneath beam assemblies to isolate thermal transfer; the high deflection resistance prevents structural warping under prolonged operation.
  • Vacuum Furnace & Sintering Units: placed in hot zones as insulation shields or structural support under inert gas. Material holds stability without deformation even in 1800°C environments.
  • Precision Devices: used as a ceramic interposer or structural board in complex electric or laboratory setups requiring wear resistance and electrical isolation.
  • Lab Device Production: R&D test rigs requiring low expansion rates and consistent geometry.

Zirconium Oxide Ceramic Sheet Usage Instructions

  • Storage: keep in dry, vibration-free packaging to avoid microcracks before use
  • Machining: avoid mechanical shock; recommend water-assisted diamond tooling
  • Cleaning: use neutral pH ultrasonics or alcohol/acetone dips
  • Surface inspection: Use a flatness gauge or profile scan before assembly
  • Assembly tips: handle with vacuum tweezers/gloves in cleanroom setups
  • Lifetime reminder: avoid sharp thermal cycling to prevent micro-structural stress

Customers are advised to avoid sudden temperature drops during furnace shutdown or disassembly.

  1. Q: Can the sheet be used as a laser reflector base?
    A: Yes. YSZ exhibits low absorption and high mechanical strength, making it suitable for laser-shaping housings.
  2. Q: Is the zirconia sheet electrically conductive?
    A: No. The material offers superior insulation (>14 kV/mm), making it suitable for high-voltage (HV) applications.
  3. Q: What edge finish can we select?
    A: Edges can be polished, chamfered, or radiused as per the customer's drawing.
  4. Q: Can this plate be used as a furnace hot wall spacer?
    A: Yes. Due to its crack resistance and thermal strength, it's commonly used inside vacuum hot zones.
  5. Q: Do you offer laser marking or identification codes?
    A: Upon request, yes. Character-based ID labels are available using ceramic-safe engraving.
