Crucibles are widely used in metallurgy, chemical processing, and a variety of industries. Among these crucibles, Graphite Crucibles are useful for the smelting of non-ferrous metals and alloys with their desirable properties. Let’s have a detailed discussion about the features, competitiveness, and uses of graphite crucibles. Hope that you can have a better understanding of graphite crucibles used for metal smelting.
Graphite crucibles are containers that can be used in high-temperature environments. They are ideal for melting aluminum, brass, gold, silver, and other non-iron metals because of their thermal conductivity, heat shock resistance, and low reactivity with molten metals.

Graphite crucibles could be categorized into three types according to their constituent materials. Artificial graphite crucibles use graphite electrode materials. Graphite-clay crucibles are made from natural flake graphite and clay. While the components of graphite-silicon carbide crucibles are natural flake graphite and silicon carbide.
Stanford Advanced Material (SAM) is a supplier of graphite crucibles of different kinds and sizes. Check our website and find the perfect graphite crucibles for your projects.
Graphite crucibles stand out for a range of thermal, physical, and chemical properties.
Different types of graphite crucibles match different metals and alloys.
Graphite-silicon carbide crucibles are suitable for copper-based alloys and aluminum-based alloys due to their thermal shock resistance.
Graphite crucibles are employed for gold and silver melting because they have a small thermal coefficient and strong strain resistance to rapid heating or cooling.
Graphite crucibles are an ideal choice for brass melting because of their durability. It could heat up quickly before the brass metal or alloy oxidizes.
