What Is a Melting Crucible? (with picture)

1/8/2020· A standard silicon carbide crucible structure would break down and contaminate the metal sample, since iron melts at 2,800 Fahrenheit (1,538 Celsius). A crucible with a graphite mixture, such as silicon carbide models have, is also not used for iron melting as the graphite dissolves in and reacts with the iron, altering its content and slowly wearing away at the crucible structure.
