Custom Zirconia Crucibles | 94-99% ZrO₂ | High-Temperature & Extreme Chemical Resistance

Zirconia Ceramic Crucibles – Engineered for the Most Demanding Applications

Our yttria-stabilized zirconia (YSZ) crucibles represent the ultimate solution for applications where extreme temperature stability, unparalleled chemical resistance, and exceptional mechanical strength are non-negotiable. Unlike conventional ceramics, zirconia's unique phase transformation toughening mechanism provides extraordinary fracture resistance and longevity under the most severe thermal and chemical environments. We specialize in fully customizable zirconia crucibles, engineered to your exact specifications for composition, geometry, size, and surface finish.

Manufactured from high-purity yttria-stabilized zirconia (typically 3-8 mol% Y₂O₃), our crucibles maintain a stable cubic crystal structure that prevents destructive phase transitions during thermal cycling. This stabilization is key to achieving:

• Ultra-high temperature capability with minimal thermal degradation

• Superior fracture toughness (highest among all advanced ceramics)

• Exceptional wear and erosion resistance

• Very low thermal conductivity for excellent thermal insulation

• Extreme Temperature Range: Suitable for continuous use up to 2200°C (3992°F) in oxidizing atmospheres, and even higher in inert or reducing environments.

• Outstanding Thermal Shock Resistance: Withstands temperature differentials exceeding 400°C without cracking, thanks to zirconia's low thermal expansion coefficient and high toughness.

• Superior Chemical Inertness: Virtually impervious to attack from most acids, alkalis, and corrosive molten metals (including reactive metals like titanium and zirconium).

• Non-wetting Surface: Minimal adhesion to most molten materials, ensuring easy sample removal and reducing contamination.

• Excellent Insulating Properties: Low thermal conductivity reduces heat loss and improves process efficiency.
