Al2O3 Crucible

Advantages of Alumina Crucible

High purity alumina crucible (alumina ≥ 99%) can be used stably in an environment of 1600 ° C for a long time, with a short-term temperature tolerance of up to 1800 ° C. Alumina Crucible has Thermal shock resistance (4 times not cracked in 1550℃), Density (3.88g/cm3), Water absorption (0.01%).

Applications of Alumina Crucible

1. In the fields of materials science, chemical analysis, etc., alumina crucibles are commonly used for high-temperature heating, melting samples (such as metals, ceramics, glass, etc.), and various component analysis.

2. In industries such as metallurgy and chemical engineering, alumina crucibles can be used for high-temperature treatment and testing of raw materials, intermediate products, and finished products, helping to optimize production processes.

3. High purity alumina crucible is a key tool for preparing high-performance ceramics, semiconductor materials, and new energy materials such as lithium battery cathode materials.

Precautions

Avoid contact with specific substances (such as F₂, Cl₂, and strongly alkaline molten salts) at high temperatures to prevent chemical reactions from damaging the crucible.
For large-volume crucibles, the increase in thermal resistance may cause changes in the weight loss rate, so it is necessary to select an appropriate size according to the experimental requirements.

Our factory

Alumina Crucible

Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.
Isostatic pressing: During the isostatic pressing procedure, binders are blended with the ceramic powder. As a result of this process, the powder transforms into freely flowing granules that can effortlessly fill the molds.
Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
