The Graphite Crucible, also known as molten copper ladle, molten copper, etc., is a class of crucibles made of graphite, clay, silica, and waxy stone. Graphite crucibles are designed for melting non-ferrous metals and their alloys, such as copper, brass, gold, silver, zinc, and lead.
As a consequence of its low coefficient of thermal expansion during high temperature use, graphite crucibles are capable of resisting rapid cold and heat with certain strain-resistance. In addition to its corrosion resistance to acidic and alkaline solutions, it is also chemically stable, and it does not participate in any chemical reactions during melting.
In the graphite crucible, the inner wall is smooth, so melted metal liquid isn’t easily riddled. This makes the metal liquid easy to cast and is suitable for casting and molding in different kinds of molds.
