SiC Graphite Crucible for Gold Melting - High Thermal Conductivity

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.

• Material: Advanced composite of Silicon Carbide (SiC) and Graphite.

• Manufacturing Process: Hot Isostatic Pressing (HIP) - Ensures maximum density, uniformity, and strength.

• Structure: Isotropic, ultra-dense, pore-free microstructure.

• Surface: Hard, glassy, oxidation-resistant SiC-rich layer.

• Primary Application: Optimized for melting and holding pure Silver (Ag) and Silver alloys.

• Performance: Superior resistance to thermal shock, oxidation, erosion, and chemical attack by molten silver/fluxes.

• Durability: Significantly longer lifespan than standard graphite or clay-graphite crucibles.

• Thermal Properties: High thermal conductivity, excellent high-temperature strength, and dimensional stability.

• Purity: Minimizes contamination of molten silver.

• Availability: Customizable sizes and shapes to fit various furnace types (induction, resistance, gas).

They can be used for resistance furnace, induction furnace, biological particles furnace, gas furnace, coke oven, furnace oil, and gas furnace to melt gold, silver, copper, aluminum, tin, lead, zinc and other nonferrous metals, and various non-ferrous alloys.

• Bullion Production: High-yield melting of 1-100kg silver bars.

• Jewelry Casting: Contamination-free melting for investment casting.

• Silver Recycling: Corrosion resistance against metallic impurities (Cu, Zn, Pb).

• Continuous Operations: 24/7 furnace compatibility with minimal degradation.
