Advantages of Cylindrical Crucibles

The main raw material for preparing cylindrical crucibles is aluminum oxide (Al₂O₃ >99.3%), alumina crucible the maximum working temperature is 1750°C, making it an ideal choice for high-temperature applications. We use recrystallized aluminum oxide in the production of high-purity alumina crucibles because this material has excellent thermal shock resistance, which benefits from its large grain size. High-purity alumina crucibles exhibit considerably strong resistance to chemical attack due to the absence of a glassy phase that determines corrosion resistance.

Applications of Cylindrical Crucibles

  1.  Alumina crucibles participate in metallurgical processes under harsh high-temperature external conditions, and their high melting point characteristics enable them to serve as stable containers, playing an important role in the safe and stable operation of induction furnaces and the quality of steel.

  2. In heating experiments involving strong oxidizing substances such as potassium permanganate, the alumina crucible will not be corroded by oxidation, ensuring the safety and accuracy of the experiment.

  3. By using methods such as slip casting molding, the size and shape of the alumina crucible can be precisely controlled to meet the needs of different experiments. Whether it is a small-scale micro experiment or a large-scale semi preparation experiment, suitable crucible specifications can be customized according to actual needs.

Instructions for Use of Alumina Crucibles

1. Before use alumina crucible, check for cracks, chips, or damage.

2. Alumina crucible thermal shock resistance is limited. Slowly heat and cool (recommended ≤5°C/min) to prevent cracking due to thermal stress.

3. Avoid hydrofluoric acid, concentrated sulfuric acid, strong alkalis (such as molten NaOH), and fluorides at high temperatures, as they may corrode the alumina crucible.

4. Use highly reactive metals (such as sodium, lithium, etc.) or melts with low oxygen partial pressure with caution, as reactions may be triggered.

5. Ensure uniform temperature distribution in the heating device (such as a muffle furnace) and provide a flat support for the bottom of the alumina crucible.

6. Reducing atmospheres (H₂, CO) may affect performance; confirm the crucible's suitability before use.

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.

  • Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.

  • Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.
