Graphite crucible is an advanced refractory material made from natural flake graphite, wax stone, silicon carbide, and other raw materials, used for smelting and casting copper, aluminum, zinc, lead, gold, silver, and various rare metals. It has the characteristics of fast thermal conductivity, high-temperature resistance, and good thermal stability, and does not react with molten materials, making it a non-ferrous metal casting tool. Its advantages include excellent crack resistance, resistance to solution loss and oxidation, shortened dissolution time, good heat transfer, high thermal conductivity, energy saving, and long service life.
