99% Alumina Ceramic Crucibles

Temperature Resistance:

• Long-term use: Up to 1600°C (2912°F).

• Short-term use: Withstands 1700–1800°C (3180°F).

• Melting point of pure alumina is ~2071°C (3760°F), but crucibles are typically rated lower due to impurities.

Design Variants:

• Shapes: Cylindrical, boat-shaped, conical, or custom designs.

• Lids: Available with matching alumina lids for contamination control.

• Capacity: Ranges from 5ml to 2000ml, with common sizes like 30ml, 100ml, and 500ml.

Applications:

• Melting/sintering metals, glass, ceramics, or fluorescent powders.

• Used in labs, metallurgy, aerospace, and chemical industries.

Advantages:

• Chemical inertness: Resists acids, alkalis, and corrosive materials.

• Thermal shock resistance: Some formulations include additives (e.g., corundum sand) to enhance durability.

• Surface finish: Options include polished, threaded, or flanged designs.
