5 FAQs of Refractory Aluminum Ceramic Crucible Cordierite Mullite Ceramic Saggar Corundum Mullite Sagger

**1. What is the maximum temperature a refractory aluminum ceramic crucible or saggar can withstand?**
Refractory aluminum ceramic crucibles and saggars made from cordierite, mullite, or corundum-mullite blends typically withstand temperatures between 1,300°C and 1,750°C. Cordierite-based products handle up to 1,300°C, while mullite and corundum-mullite saggars endure higher ranges (1,600°C–1,750°C). Exact limits depend on material composition and manufacturing quality.

**2. How do cordierite, mullite, and corundum-mullite differ in performance?**
Cordierite excels in thermal shock resistance, ideal for rapid heating/cooling cycles. Mullite offers better high-temperature stability and chemical resistance. Corundum-mullite combines alumina (corundum) and mullite for superior mechanical strength and maximum heat resistance, suited for extreme temperatures but less thermal shock tolerance than cordierite.

**3. Are these ceramics resistant to chemical corrosion or slag erosion?**
Yes. Mullite and corundum-mullite saggars resist acidic/alkaline slag and molten metals, making them suitable for metallurgy or glassmaking. Cordierite has moderate chemical resistance but may degrade under prolonged exposure to aggressive fluxes. Material selection should align with the application’s chemical environment.

**4. What industries commonly use these ceramic crucibles and saggars?**
They are used in metallurgy (melting alloys), ceramics (kiln firing), electronics (component sintering), and glassmaking. Cordierite saggars suit pottery, while corundum-mullite is preferred for high-purity materials like lithium battery powders or refractory metal processing.

**5. How can I extend the lifespan of a ceramic crucible or saggar?**
Avoid sudden temperature changes to prevent cracking. Preheat gradually (3–5°C/min) and cool slowly. Clean residues after use with non-abrasive tools. Store in dry conditions to prevent moisture absorption. Do not overload or expose to temperatures beyond the material’s limit. Proper handling reduces thermal stress and wear.
