Aluminum Titanate Ceramic Crucible Overview

Aluminum titanate ceramic crucibles are advanced refractory containers made from aluminum titanate (Al₂TiO₅), specially designed for handling and melting non-ferrous metals such as aluminum and its alloys. These crucibles provide exceptional thermal shock resistance, very low thermal conductivity, and excellent resistance to wetting and corrosion by molten metals. Their stable, non-reactive surface and high-temperature durability make them ideal for casting, melting, and holding operations where long service life and clean metal processing are essential.

Applications

• Melting and holding molten metals: Used in furnaces and casting systems for reliable metal containment.

• Low-pressure die casting (LPDC) systems: Serve as stable, non-wetting containers during controlled metal transfer and casting.

• Degassing and refining processes: Employed during molten metal treatment to ensure clean, impurity-free aluminum.

• Laboratory and research use: Suitable for high-temperature testing and metal sample preparation in metallurgical research.

Packaging

Products are packaged in customized cartons or wooden crates according to size. Small items are securely packed in polypropylene (PP) boxes, while larger items are placed in custom wooden crates. Appropriate cushioning materials are used to protect the crucibles during transportation.

Manufacturing and Testing

Testing procedures include:

• Chemical composition analysis to verify purity and compliance with standards.

• Mechanical property testing including tensile strength, yield strength, and elongation.

• Dimensional inspection to ensure thickness, width, and length meet specified tolerances.

• Surface quality inspection to detect defects such as scratches, cracks, or inclusions through visual and ultrasonic examination.

• Hardness testing to confirm uniformity and mechanical reliability.
