Buy low price high quality Graphite Carbon Crucible for vacuum coating of gasification aluminum. Graphite Carbon Crucible is a container made of graphite and carbon materials used to melt and hold metals at high temperatures. These crucibles are essential in metal casting, foundries, and laboratory applications due to their excellent thermal conductivity, high-temperature resistance, and chemical inertness.
Key Features of Graphite Carbon Crucible:
| Property | Description |
|---|---|
| Material | Graphite (natural or synthetic) + bonded carbon |
| Max Temperature | 🔥 Up to 1600–3000°C (depending on grade) |
| Thermal Conductivity | High – promotes even heating |
| Thermal Shock Resistance | Excellent – can withstand rapid heating/cooling |
| Chemical Resistance | Inert to most acids, alkalis, and slags |
| Non-wetting Surface | Resists adhesion of molten metals |
Applications:
Melting non-ferrous metals: gold, silver, aluminum, copper, brass, zinc, etc.
Foundries and casting shops
Laboratories for high-temp experiments
Jewelry making
Glass and ceramics industries
Metal refining and alloying
Advantages:
Withstands extremely high temps
Long life span with proper use
Minimizes contamination of melt
Efficient heating due to high conductivity
Cost-effective in bulk
Types of Graphite Crucibles:
| Type | Features |
|---|---|
| Clay Graphite Crucible | Graphite + clay binder; lower cost |
| Isostatic Graphite Crucible | Very fine-grain, high purity |
| Machined Graphite Crucible | Custom sizes and shapes available |
| SiC-Graphite Crucible | Enhanced strength and oxidation resistance |
