Advantages of Industrial Alumina Ceramic Crucible
1. Alumina ceramics have strong compressive strength, are not easily damaged, and reduce replacement and maintenance costs.
2. Alumina ceramic crucibles can withstand rapid heating and cooling temperature changes, avoiding the risk of explosion, and has slow heat transfer, making it less prone to burning hands when held.
3. Alumina ceramic crucibles do not release harmful substances during use, meeting environmental protection requirements.
Application of Industrial Alumina Ceramic Crucible
In chemical laboratories, the high purity (usually ≥ 99%) and chemical inertness of alumina ceramic crucibles make them ideal reaction vessels.
Alumina ceramic crucible is used in the material preparation process for melting high-purity metal or ceramic powders.
In the field of environmental science, Alumina ceramic crucible can be used to simulate material stability testing under high temperature, high humidity, or corrosive media.

Factory Equipment
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.
