Graphite Crucible For Melting Gold
Features
Precious metal smelting is classified to primary smelting and refining. Refinery means getting high purity precious metal through smelting low purity metals, where graphite crucibles are needed with high purity, high bulk density, low porosity and good strength.
1. High temperature resistance, melting point 3850 ± 50 ° C, boiling point 4250.
2. Low ash content, high purity, to avoid contamination of your product.
3. Graphite is easy to process into any shape you like.
4. High mechanical strength
5. Good sliding performance
6. High thermal conductivity
7. High thermal shock resistance and chemical resistance
8. High corrosion resistance and oxidation resistance
9. Good conductivity
10. High density and high mechanical strength
11. The coefficient of thermal expansion is very small, and it has certain strain resistance for rapid cooling and heating.
12. Graphite crucibles have strong corrosion resistance and excellent chemical stability for acidic and alkaline solutions. Therefore, it does not participate in any chemical reactions during the smelting process.
13. The inner wall of the graphite crucible is smooth. The molten metal liquid is not easy to leak or adhere to the inner wall of the crucible, therefore it has good flowability and pouring ability.
