Silicon Carbide Graphite Crucible for Copper Melting

The Silicon Carbide Graphite Crucible represents a revolutionary advancement in refractory engineering, meticulously designed for extreme metallurgical processes. This premium composite vessel synergizes silicon carbide (SiC) with graphite through proprietary gradient sintering technology. The result is a crucible architecture that delivers unprecedented performance in thermal management, mechanical resilience, and chemical inertness - specifically optimized for copper and copper alloy applications.

• 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.
• High Thermal Conductivity: Ensures rapid and uniform heat distribution for efficient and energy-saving gold melting operations.
• Excellent Chemical Inertness: Demonstrates minimal reactivity with molten gold and common fluxes, preserving gold purity and minimizing metal loss through slag formation or crucible attack.

Qingdao Baidun's SiC Graphite Crucibles deliver uncompromised performance in high-purity copper processing - where crucible failure risks catastrophic contamination. Engineered for extreme thermal cycling and aggressive metallurgical environments.

Silicon carbide graphite crucibles deliver unmatched versatility across all major furnace types - including resistance, induction, biomass particle, gas-fired, and coke ovens - enabling efficient melting of precious metals (gold, silver), base metals (copper, aluminum, tin, lead, zinc), and specialized non-ferrous alloys.

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