Silicon Carbide Graphite Crucible for Copper Melting
The Silicon Carbide Graphite (SiC Graphite) Crucible is a premium refractory vessel specifically engineered for the demanding process of copper melting and refining. This high-performance composite crucible combines silicon carbide (SiC) with crystalline graphite, delivering unmatched thermal, mechanical, and chemical properties for extreme melting applications.
- Exceptional Thermal Stability: Withstands temperatures exceeding 1100°C without deformation or cracking, even under rapid thermal cycling.
- Superior Oxidation Resistance: Highly resistant to oxidation in air at elevated temperatures, protecting crucible integrity and minimizing contamination.
- High Thermal Conductivity: Ensures rapid and uniform heat distribution for efficient, energy-saving melting operations.
- Excellent Chemical Inertness: Demonstrates minimal reactivity with molten metals, preserving purity and minimizing metal loss.
