What Material is a Crucible Made of? Refractory Metals

2022217 This is why the crucible material should always have a much higher melting point than the materials to be melted in the crucible Sometimes crucibles are made of steel or iron to melt softer metals such as aluminum and zinc This is because this egory of metals melts at a temperature lower than that of the crucible material
