From small graphite crucibles (10mm-1000mm) for laboratory use to large graphite crucibles (1kg-50kg+) for foundry and metal melting applications, we provide high-quality graphite containers with precise dimensions. Custom sizes are available upon request to ensure optimal performance in your specific process.Graphite crucibles are made from high-purity graphite through a specialized production process. First, premium graphite powder is mixed with a binder to form a dense, moldable material. The mixture is then pressed or extruded into the desired graphite crucible shape. After drying, the graphite undergoes high-temperature sintering to enhance strength and thermal stability. Finally, each graphite crucible is precision-machined for smooth surfaces and consistent wall thickness, ensuring durability and superior heat resistance.ModelDensity(g/cm3)Compression Strength(Mpa)Flexural Strength(Mpa)Resistance(μΩm)Ash(%)Grain Size>=>=>=<=<=721.62281480.31,2,4mm721.7236187.50.32,0.8mm751.7548247.50.3325mesh801.8052287.50.2325mesh851.85623670.2325meshGraphite crucibles, supporting customization in various specificationsNotes of operating graphite crucibles1. The crucible should be stocked in the dry situation2. Carry the crucible lightly3. Warm the crucible in the drying machine or near thefurnace. The warming temperature should be up to 500oC.4. The crucible should be put under the furnace month flat.5.When put the metal into the crucible, you should take the crucible capacity as your reference. If the crucible is too full, it will be damaged by expansion.6.The clamps shape need as that of crucible. Avoid theconcentrate stressed destroy of the crucible.7. Clean the crucible regularly and lightly.8. The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace.9. Turn the crucible once in one week and this will help lengthen the service life.10. The flame should not touch the crucible directly.11.24 hours constant use will make crucibles have longer service life.The smelt soup in the crucible should be cleared out when the furnace stop working, in order to avoid molten soupsolidificating and will be expanded when fire to reheat, and affect the service life of crucible or even burst.12. We suggest that about 2 months for crucible melting aluminum alloy (every week for melting copper alloy), hanging out to check whether there is something wrong in the surface, and clean furnace hearth as well as turn the crucible, this operation ishelpful to prolong the service life of crucible.
