Do you know how many kinds of graphite crucibles we have?
1. According to your application. For example if you need crucible to melt jewelry, gold, silver and other precious metal. We will suggest the high purity graphite for you, because it does not have impurity and will not influence your precious metal.
2. According to your working temperature. For example, if your working temperature is within 500 degree, the ordinary graphite with density 1.75g/cm3 is OK. If your working temperature is more than 2000 degree, I think we must consideration the isostatic graphite with the high density.
3. According to your thermal shock property. For example, in the same temperature 200 degree, the different time will bring different influence.
4. According to your acid-base property. For example, if your working environment is strong acid or strong base, we will suggest impregnation for you.
Do you know how to choose graphite crucible?
1. Confirming your use, which metal you want to smelting.
2. Confirming your working temperature.
3. Confirming your thermal shock property, it is mean the time of your heating from the 0 degree to the highest temperature.
4. Confirming your working environment. When you melting, the crucible is in the air of vacuum.
5. Confirming your acid-base property.
