Ceramic compounds as compared to metallic compounds

ANS:C - have higher melting temperature.

Ceramic compounds typically have higher melting temperatures compared to metallic compounds. This means that they require more energy to break the strong bonds holding their atoms together in the solid state, leading to a higher temperature needed for melting. This property arises from the nature of the chemical bonds present in ceramics. Ceramic materials often consist of ionic or covalent bonds, which are generally stronger than metallic bonds found in metals. These strong bonds result in a higher energy requirement to overcome them and transition the material from a solid to a liquid state. As a result of their high melting temperatures, ceramics are commonly used in applications where thermal stability and resistance to high temperatures are required. Examples include refractory materials for furnaces, kiln linings, thermal insulation, and protective coatings for components exposed to extreme heat conditions.
