Zirconia Crucible | High-Temperature ZrO₂ Ceramic Crucible for Metal Melting

Premium Zirconia Crucibles for Extreme Conditions
Zirconia crucibles (ZrO₂ ceramic crucibles) are high-performance refractory containers designed for extreme temperatures up to 2000°C. Renowned for their exceptional thermal shock resistance, chemical inertness, and corrosion resistance, they are the preferred choice for melting rare and precious metals like platinum, palladium, and superalloys.
Zirconia Crucible Specifications
| Working Temperature | 2000℃ |
| OD | 15~80 mm |
| Height | 20~115 mm |
| Wall thickness | 1.5~5 mm |
Different sizes and shapes of zirconia crucibles can be manufactured according to customers’ requirements. Please send us an inquiry for the zirconia crucible price.
Available in yttria-stabilized zirconia (YSZ) and magnesia-stabilized zirconia (MSZ), these crucibles excel in harsh environments, including metallurgy, aerospace, electronics, and advanced material research.
Two Grades of ZrO₂ Crucibles for Different Applications

Ceramic grade zirconia crucible
1. Refractory-Grade Zirconia Crucible (Semi-Ceramic)
Stabilizer: Yttrium oxide (Y₂O₃)
Density: 4.5 g/cm³ (microporous structure)
Max. Temperature: 2000°C
Key Features:
Superior corrosion resistance against acids, alkalis, and metal slags
Outstanding thermal shock resistance for rapid heating/cooling cycles
Stable in both oxidizing and reducing atmospheres
Ideal for platinum group metal (PGM) smelting
2. Ceramic-Grade Zirconia Crucible (Fully Dense)
Stabilizer: Magnesium oxide (MgO)

MgO Crucible
Density: 5.7 g/cm³ (fully dense structure)
Max. Temperature: 2000°C
Key Features:
Exceptional chemical stability (resistant to most acids, alkalis, and molten metals)
Low thermal conductivity and minimal high-temperature creep
Thermal expansion coefficient close to metals, reducing stress during heating
Perfect for high-purity alloy melting and thermal analysis
