Clay Graphite Crucible

Clay graphite crucibles are made of a mixture of graphite and clay. These crucibles are suitable for smelting and casting non-ferrous metals and can handle large quantities of material. Their thick inner walls can withstand direct heating and open-fire foundries.

These crucibles are important containers for melting and casting metals such as gold, silver, aluminum and brass due to their excellent thermal conductivity, high temperature resistance and resistance to thermal expansion under extreme conditions. In addition, clay graphite crucibles have strong resistance to chemical corrosion from acid and alkaline solutions, ensuring long-term stability.

DECENT clay graphite crucible adopts high-quality raw materials and advanced formula combination, with the characteristics of anti-oxidation, stable performance, long service life, while also ensuring the purity of molten metals.

Equipment Construction

The inner wall of the crucible is smooth to prevent the leakage and adhesion of the molten metal.
During high-temperature operation, the thermal expansion coefficient is small, and it has a certain ability to resist rapid cooling and heating strain.
Graphite crucibles have various shapes and specifications, with a wide range of applications.
Available in a diversity of sizes, from small containers to large containers that can hold tons of molten metal, meeting a variety of smelting needs.
Graphite clay crucibles have strong corrosion resistance to acid and alkali solutions, with good chemical stability.
