Silicon Carbide Graphite (SiC-Graphite) crucibles are advanced composite ceramics engineered for high-temperature melting of precious metals (especially gold, silver, platinum). They combine silicon carbide (SiC) and graphite via processes like isostatic pressing and high-temperature sintering, creating a material that overcomes the limitations of pure graphite or SiC crucibles.
-
Chemical Inertness
-
Resists reaction with molten gold, silver, or fluxes (e.g., borax), preserving metal purity.
-
-
High Mechanical Strength
-
SiC backbone resists abrasion from molten metal stirring/scraping.
-
3–5× longer lifespan than traditional crucibles.
-
-
Low Metal Adhesion
-
Molten gold "beads up" instead of wetting the surface, ensuring clean pours and minimal residue.
-
-
Enhanced Oxidation Resistance
-
SiC shields internal graphite; some models feature anti-oxidation coatings.

| Aluminum Alloys | 900 | Prevents Al penetration • Flux corrosion resistance |
| Zinc/Tin/Lead | 750 | Longevity in low-melt applications |
Key Considerations
-
Avoid Impact: Do not drop or strike (despite high strength).
-
Control Oxidation: Limit exposure to air above 800°C; store dry.
-
Preheating: Gradually heat new crucibles to 300°C to remove moisture.
-
Flux Use: Avoid highly corrosive fluxes (e.g., nitrates).
-
Thermal Cycling: Minimize extreme temperature swings (>800°C/sec).
