Feature

●★ Graphite Crucibles properties - Excellent thermal stability, fast heating and cooling / good acid and alkali resistance / good thermal conductivity, greatly shortening the melting time, energy savings / shock resistance, ensuring the reliability of the product.
●★ Made of Graphite, high quality Induction Furnace Graphite Crucible. Comes with a silicon dioxide (SiO2) jacket to prevent melting material leaking in case the graphite crucible breaks.
●★Specification Capacity - Capacity: 300 ML,Molten gold: 4 kg,Silver melt: 2 kg,Inner diameter: 60 mm/2.4 inch,Outer Size: 85 mm/3.3 inch Diameter x 130 mm/5.1 inch Height.
●★ Pure Graphite Crucibles cannot be heated in a coal or charcoal oven. It will be oxidized and broken; pure graphite will begin to oxidize at 400°C (752°F). If an air heater is used, the temperature can withstand up to 3200°F. If a vacuum or gas protection supply is used, the temperature can withstand up to 5000°F.
●★ Graphite Crucibles application scene - mainly used for gold and silver purification, metal molding, university experimental equipment, tannic acid corrosion, helium temperature analysis, small molding, special alloy.
