A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white-hot. Graphite crucible can withstand the high temperatures and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and, etc.

 features
1. Thermal stability: According to the quench acute thermal using conditions of graphite crucible, we will specially design the production procedure, to ensure the reliability of product quality. 
2. Corrosion resistance: Even and fine basic design will delay the erosion of the crucible. 
3. Impact resistance: Graphite crucible can bear high thermal impact, so any process can be carried out. 
4. Acid resistance: The addition of special materials will greatly improve the quality of the crucible, especially its index of acid resistance, and will prolong the service life of graphite crucible. 
5. High heat Conduction: High content of fixed carbon ensures good heat conduction, shortens the time of dissolution, and reduce energy consumption.
6. Control of metal pollution: The component of material under strict control will ensure that graphite crucible will not pollute the metals when dissolving. 
7. Quality stability: The process technology of forming under high pressure and quality guarantee system will fully ensure the stability of quality

 applications
Due to the above excellent properties, graphite crucible is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys.
Graphite crucible can be used for non-ferrous metal smelting and casting, dissolving gold or silver ornaments, analysis of special type steel, sintering hard metal.
Graphite crucible widely used in such fields as industrial furnaces, monocrystalline silicon machinery, electron, semiconductor, metallurgy, oil, chemistry, textile, electrical machinery, electrical equipment, electrical furnace, traffic, communication industry, medicine, etc.
