*Important note: Pure graphite crucible can NOT be heating by Carbon furnace or charcoal kiln. It will be oxidized and cracked.
Composition: Graphite ≥ 99.9%; Ash≤0.1% (protect the precious metals from contamination while smelting)
●Well thermal stability : Capable of fast heating and cooling according to the using conditions of graphite crucible.
●Excellent corrosion resistance, impact resistance, acid resistance and alkali resistance.
●Great heat transfer performance: highly shorten the melting time and save energy.
●Small thermal expansion coefficient in high-temperature using process and certain strain resistance to the thermal shock, quenching.
●Graphite Crucible is Generally used in alloy tool steel smelting and smelting of nonferrous metals and their alloys.
●Graphite is more durable than ordinary material products, which makes graphite crucible to have long service life under correct using condition.
Stored in dry place, do not get it wet.
After drying the crucible, please avoid the water.
Be careful not to give a mechanical impact force, not from a fall or impact.
1x Graphite Crucible (well packaged)
