good thermal conduction, at high temperatures, good wearability, high mechanical strength.
High Purity Graphite Crucible for Jewelry Industry
Main ingredients for graphite crucible are natural flake graphite and binder. It mainly used in the smelting of precious metals such as gold and silver, single crystal polycrystalline silicon purification. This kind of graphite crucible is with high purity, highly erosion resistant of metal solution and service life is long.
The selected graphite material is with the following characteristics:
1. High heat resistance: fire resistance is very high, the maximum temperatures up to about 2000°C.
2. Thermal stability: graphite crucible for acute thermal quenching of the conditions of use, specifically designed to ensure the reliability of product quality.
3. Corrosion resistance: substrate of uniform fine design, slow down the corrosion of crucible.
4. Impact resistance: graphite crucible can bear high thermal shock strength, so any process can rest assured.
5. Acid resistance: joining special materials significantly improved quality of crucible, acid and indicators of performance, and greatly extend the service life of graphite crucible.
6. High heat conduction: high levels of fixed carbon ensures good thermal conductivity, it can shorten dissolved time, and significantly reduces energy consumption.
7. Metal pollution control: strict control of the material composition, it can guarantee that the graphite crucible has no pollution to the metal while being dissolved.
8. Quality stability: high pressure forming method of production technology to ensure the stability of the quality
9. Blocking resistance: for graphite has the characteristic of not easy blocking with molten soup and with less saturated and viscosity of molten soup.
Our company can design and machine all kind of dimension graphite crucible according to the requirements and drawings of customers.
