High-Performance Graphite Crucible for Metal Melting & Casting
A Graphite crucible is a refractory container made primarily from natural or synthetic graphite. It is used for melting and holding metals at high temperatures due to its exceptional thermal conductivity, resistance to thermal shock, and chemical inertness.Material: High-purity carbon graphiteMaximum Operating Temperature: Up to 3000°C (5432°F) in a non-oxidizing atmosphereCommon Sizes: 1kg to 500kg metal capacityApplications: Melting gold, silver, copper, aluminum, and other non-ferrous metals; laboratory assays; glass melting.Advantages over ceramic crucibles: Faster heating, lower energy consumption, longer lifespan, and no metal contamination.Lifespan: Typically 3–6 months in continuous industrial use, depending on operating conditions.Disposal: Graphite Crucibles are non-toxic and can be recycled or crushed for use as Carbon Additive in steelmaking.
