Melting Point of Ceramic Materials
Ceramics are typically composed of ionic or covalent bonds, which are very strong and require a lot of energy to break. As a result, they tend to have very high melting points, often exceeding 1000 °C (1832 °F).
The following table provides a comprehensive list of melting point values for different ceramic materials at 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
