Zirconium Oxide Crucible

Zirconium Oxide Crucible

Zirconium Oxide (Zirconia or \(ZrO_{2}\)) crucibles are ultra-high-temperature and chemically inert containers capable of withstanding temperatures exceeding \(2300^{\circ }\text{C}\).

Due to their remarkable thermal stability and non-wetting properties, they are highly sought after for demanding industrial and laboratory applications.

Primary Applications

Precious Metals & Superalloys: Used for melting, purifying, and casting high-purity metals such as platinum, palladium, cobalt, and nickel-based superalloys.
Analytical Chemistry: Employed for aggressive alkaline fusions (using sodium carbonate or sodium peroxide) and acid digestions.
Specialty Glass Production: Utilized in glass tank kilns and for melting specialty quartz glass without contaminating the final product.
Advanced Ceramics & Sintering: Provides the uniform heating and extreme thermal stability required to sinter technical ceramics.
Biomedical Manufacturing: Utilized in the investment casting of chrome-containing alloys for orthopedic and dental implants.

Key Material Advantages

Extreme Heat Resistance: Withstands temperatures up to \(2700^{\circ }\text{C}\).
Chemical Inertness: Impervious to most strong acids, alkalis, and molten metals, preventing contamination of the material being processed.
Thermal Shock Resistance: Low thermal expansion means they can handle rapid heating and cooling cycles.
Non-wettability: Melted metals do not easily “stick” or wet the crucible walls, ensuring clean pours and easy recovery of samples.

Zirconium Oxide Crucible

They deliver cleaner melts at temperatures up to 1900°C and beyond.

They are engineered for the melting of superalloys and precious metals and deliver heat-up and cool-down schedules that keep your foundry productive.
