Product Description
The Silicon Carbide Graphite (SiC Graphite) Crucible stands as the premier refractory vessel solution meticulously
engineered to meet the extreme demands of copper melting, alloying, holding, and refining processes. Unlike standard refractories, this advanced composite crucible is
specifically formulated to overcome the unique challenges posed by
molten copper and its alloys - including high operational
temperatures (exceeding 1085°C / 1985°F), aggressive slag
formation, high fluidity leading to penetration risks, and the need
for precise thermal management.
Product Features
- Exceptional Thermal Stability: Withstands the high temperatures (exceeding 1100°C) required for
gold melting without deformation or cracking, even under rapid
thermal cycling.
- Superior Oxidation Resistance: Highly resistant to oxidation in air at elevated temperatures,
protecting the crucible integrity and minimizing contamination of
the precious metal melt.
- Superior Resistance to Metal Penetration: The dense, low-porosity microstructure achieved through advanced
manufacturing significantly impedes the infiltration of highly
fluid molten copper and copper alloys, a major failure mode for
inferior refractories. This extends service life dramatically.
- Reduced Wetting & Easier Release: The graphite component minimizes the wetting tendency of molten
copper, facilitating cleaner pours and reducing residual metal
buildup inside the crucible.
