Ceramic Crucible

Overview of Ceramic Crucible

Our advanced ceramic crucibles are engineered for high-purity melting, holding, and processing of demanding materials. Manufactured from a range of premium technical ceramics like alumina, zirconia, and magnesia, they offer exceptional resistance to thermal shock, chemical corrosion, and mechanical wear at extreme temperatures, ensuring process integrity and longevity in critical applications.

Features of Ceramic Crucible

• Ultra-High Purity: Minimizes contamination for sensitive processes in metal, semiconductor, and research applications.
• Superior Thermal Shock Resistance: Withstands rapid temperature cycling without cracking, ensuring reliability from pre-heat to full operation.
• Excellent Chemical Inertness: Resists corrosive attack from molten metals, slags, fluxes, and salts.
• High-Temperature Stability: Maintains structural integrity and mechanical strength in environments exceeding 1700°C.
• Non-Wettable Surfaces: Certain compositions prevent adhesion of molten material for cleaner pours and easier residue removal.

Applications of Ceramic Crucible

• Metal & Alloy Production: Melting and casting of precious metals, superalloys, and reactive metals.
• Semiconductor & PV Industry: Processing of silicon, gallium arsenide, and other source materials.
• Research & Development: Laboratory analysis, sample preparation, and materials synthesis.
• Glass & Enamel Production: Holding and processing of raw materials and colored frits.
• Chemical Processing: Acting as a reactor or container for high-temperature chemical reactions.

5 FAQs of Ceramic Crucible

1. How do I choose the right crucible material for my application?
Selection depends on the material being melted and the process temperature. Alumina offers a great balance of properties, Zirconia is ideal for ultra-high temperatures, and Magnesia is suited for basic environments. Consult our engineers for guidance.

2. What is the maximum heating rate for your crucibles?
While highly thermal-shock resistant, we recommend controlled heating and cooling cycles (typically 5-10°C per minute) to maximize service life, especially for larger crucibles.

3. Can you manufacture custom crucible shapes and sizes?
Yes. We specialize in custom fabrication and can produce crucibles with specific geometries, lids, spouts, and capacities to meet unique process requirements.

4. How does your crucible ensure purity?
We use high-purity raw materials and controlled manufacturing processes to prevent contamination, which is critical for semiconductor and research applications where even trace elements can compromise results.

5. What is the typical service life of a ceramic crucible?
Service life varies greatly with operating conditions, including temperature, cyclicity, and material corrosiveness. Proper pre-treatment and careful handling significantly extend crucible lifespan.
