Graphite Crucibles for Metal Smelting

The main raw materials for graphite crucibles include graphite, silicon carbide, silica, refractory clay, pitch, tar, etc. Graphite crucibles have good thermal conductivity, high temperature resistance, small coefficient of thermal expansion during using at high temperatures and certain strain resistance to rapid heat and cold. Meanwhile, they are highly resistant to acid/alkaline solutions and exhibit excellent chemical stability.

Therefore, graphite crucibles are widely used in industrial sectors such as metallurgy, casting, mechanical, and chemical engineering. They are commonly used in the smelting of alloy tool steel, non-ferrous metals and alloys.
