1. During high-temperature use, it has a small thermal expansion coefficient, has certain adaptability, and can quickly cool and heat. 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 molten metal is not easy to leak and adhere to the inner wall of the crucible, so that the molten metal has good fluidity and castability, and is suitable for various mold castings.
3. Because graphite crucible has the above excellent characteristics, soMainly used for smelting copper, brass, gold, silver, zinc, lead and other non-ferrous metals and their alloys.
