Heat Resistant Crucibles

Description

Heat Resistant Crucibles are mainly made of alumina ceramics, also known as alumina or aluminum oxide (Al2O3), which is an industrial oxide ceramic known for its extremely high hardness and high thermal conductivity. The characteristics of alumina ceramics make them one of the most widely used ceramics in structural, wear and corrosion environments.

Advantages of Heat Resistant Crucibles

Alumina crucible high temperature resistance,long-term use at 1600 ℃, short-term use at 1800 ℃(Al2O3≥99%).
Alumina crucible has chemical resistance and corrosion resistance, making it suitable for use in hazardous chemical environments.
Alumina crucible wear resistance is a long-term investment for enterprises, reducing replacement and maintenance costs.

Applications of Heat Resistant Crucibles

1. Alumina crucible is used in applications involving molten steel, aluminum, or other metals.

2. Alumina crucibles are used for high-temperature melting experiments, sintering of metals, glass, ceramics, and chemical reactions in strong acid or alkali environments.

3. Alumina crucibles are used in processes involving reactive metals or other chemicals that rapidly degrade other materials.

4. Alumina crucibles are crucial in laboratories for high-temperature reactions, material testing, and ceramic and glass synthesis.

5. Alumina crucibles are used for high-temperature melting and material research in the semiconductor industry.

6. Alumina crucibles are used in jewelry production to melt precious metals.

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.
