Premium 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.
Key Features
- 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.
