Carbon Bonded Silicon Carbide Crucibles are widely used in the smelting and casting fields of different non-ferrous metals such as copper, aluminum, gold, silver, lead, zinc and alloys. The use of these crucibles results in consistent quality, long service life, greatly reduced fuel consumption and labor intensity. In addition, it improves work efficiency and provides excellent economic benefits.

Materials and Construction
Graphite crucibles are composed of several materials:

• Graphite (45-55%): The core component, providing excellent heat transfer and thermal stability.
• Silicon carbide, silica, and clay: These materials enhance the crucible's mechanical strength and resistance to corrosion, especially in extreme temperature environments.
• Clay binder: Ensures proper cohesion of the materials, giving the crucible its shape and structural integrity.

The particle size of graphite used also varies depending on the crucible’s size and purpose. For example, larger crucibles use coarser graphite, while smaller crucibles require finer graphite for better precision and performance.

Applications of Graphite Crucible
Graphite carbon crucibles are widely used across different sectors:

• Non-ferrous metal casting: Ideal for metals like copper, gold, silver, and brass due to their low coefficient of thermal expansion.
• Induction furnaces: In some cases, crucibles are designed to work with specific furnace frequencies to optimize energy efficiency and temperature control.
• Chemical processing: Their chemical stability makes them suitable for use in environments exposed to acidic or alkaline materials.

Crucial Maintenance Tips
To maximize the lifespan of a graphite carbon crucible, proper care and storage are essential:

1. Cooling: Ensure the crucible cools down completely before storage to prevent thermal shock.
2. Cleaning: Always remove residual metal and flux after each use to prevent contamination.
3. Storage: Store the crucible in a dry environment, away from direct heat sources, to avoid moisture absorption, which can lead to structural degradation.
