Silicon Carbide Graphite Crucible for Silver Melting

Engineered for Peak Performance in Precious Metal Processing: Our Hot Isostatically Pressed Silicon Carbide Graphite (SiC-Graphite) Crucible is the premium solution for demanding silver melting applications. Manufactured using advanced isostatic pressing technology, this crucible combines the exceptional high-temperature strength and thermal conductivity of graphite with the superior hardness, oxidation resistance, and chemical inertness of Silicon Carbide (SiC). This unique composite structure delivers unparalleled durability, longevity, and process reliability when melting pure silver and silver alloys at high temperatures.

• Exceptional Thermal Shock Resistance: The HIP process creates an isotropic (uniform in all directions), ultra-dense microstructure. This enables the crucible to withstand extreme and rapid temperature fluctuations inherent in silver melting cycles (charging solid metal, rapid heating to melting point >960°C, pouring, cooling) without cracking or spalling.

• Superior High-Temperature Strength & Stability: Maintains structural integrity and dimensional stability at the high temperatures required for silver melting and holding, resisting deformation or sagging under the weight of molten metal.

• Unmatched Oxidation & Corrosion Resistance: The dense SiC surface layer formed during HIPing acts as a robust barrier against oxidation and erosion from molten silver and common fluxes. This minimizes crucible degradation, prevents contamination of the melt, and significantly extends service life.

• Enhanced Purity & Reduced Metal Contamination: The non-wetting properties of SiC and the extreme density achieved by HIPing drastically reduce slag build-up, metal penetration, and chemical reaction with molten silver. This ensures higher purity of the melted silver and minimizes metal loss.

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.

• Copper: OFC, bronze, brass melting
• Aluminum: Alloy production, recycling
• Precious Metals: Gold, silver refining
• Specialty Processes: Vacuum melting, induction furnaces
