Casting crucible (silicon carbide crucible, graphite crucible, etc.) use tutorial

What is a casting crucible? A crucible is a container for metals with high melting points. (Gold 1064°C, silver 962°C, copper 1083.4°C, cast iron 1200°C, iron 1535°C, aluminum 660°C.) Types of Casting Crucible: What are casting crucibles made of: Graphite Crucible : It refers to a kind of crucible made of graphite, clay, silica and wax stone. Graphite crucibles are mainly used for melting non-ferrous metals and their alloys, such as copper, brass, gold, silver, zinc and lead. Quartz Crucible : The main chemical composition of quartz crucible is silicon dioxide. It has the advantages of high purity, strong temperature resistance, large size, high precision and good heat preservation. It is commonly used for pulling semiconductor materials such as large diameter single crystal silicon. Porcelain Crucible: Porcelain crucible is the main component of chemical laboratory supplies: alumina (45-55%), silica...
