Corundum silicon carbide castable crucible is widely used in high temperature industry

Corundum silicon carbide castable crucible is a commonly used container in high temperature industry. It uses corundum silicon carbide castable as raw material and has excellent high temperature stability, wear resistance, slag resistance, thermal shock resistance and chemical stability. It is suitable for metal smelting, glass manufacturing, ceramic industry, chemical laboratories and other occasions.

High temperature tolerance

Corundum silicon carbide castable crucibles can withstand temperatures up to 1700℃ or even higher due to the excellent properties of its main components - corundum, silicon carbide and activated alumina. Under high temperature conditions, a dense liquid film will form on the surface of the crucible, which makes it have excellent alkali resistance.

In addition, the matrix part of the crucible will react in situ at high temperature to form mullite phase, which further enhances its thermal shock stability and wear resistance. This design makes the corundum silicon carbide castable crucible highly resistant to erosion by alkaline media.

Various applications

Corundum silicon carbide castable crucibles are usually manufactured in cylindrical or conical shapes, with a narrow bottom and a wide top, sometimes with ears or supports for easy handling and operation. According to the needs of different industries, its main applications include:

• In metal smelting, it is mainly used to melt metals or alloys.
• In chemical experiments, it is mainly used to heat solid substances or conduct high-temperature chemical reactions.
• In the glass and ceramic industries, it is mainly used to melt raw materials and prepare glass or ceramic glazes.

Material selection

In addition to corundum silicon carbide, common crucible materials include clay, adaptable and ceramic. When choosing a crucible material, it is necessary to make a reasonable decision based on the temperature, chemical stability and medium properties of the specific medium. For example, for high temperature and strong acid/alkali environments, corundum silicon carbide crucibles are ideal choices.

In summary, the corundum silicon carbide castable crucible provides reliable support for the core equipment in the high-temperature industry with its excellent physical and chemical properties, and its wide application proves its irreplaceable value.
