Application

1. In the process of high temperature use, the coefficient of thermal expansion is small, and it has certain strain resistance torapid cooling and rapid heating. It has strong corrosion resistance to acidic and alkaline solutions, has excellent chemical stability, and does not participate in any chemical reactions during the smelting process.

2. The inner wall of the graphite crucible is smooth, and the melted metal liquid is not easy to leak and adhere to the inner wall of the crucible, so that the metal liquid has good fluidity and castability, and is suitable for various mold casting.

3. Because graphite crucible has the above excellent characteristics, it is mainly used to smelt non-ferrous metals such as copper, brass, gold, silver, zinc and lead and their alloys.
