What is a key characteristic of ceramics in manufacturing?

Ceramics are renowned for their exceptional heat resistance and durability, making them a vital material in various manufacturing processes. This characteristic stems from their molecular structure, which typically involves strong ionic and covalent bonds. The strong bonding results in materials that can withstand high temperatures and maintain their integrity without deforming or breaking down, which is crucial in applications such as aerospace, automotive, and electronics.

Moreover, ceramics have low thermal and electrical conductivity, which enhances their reliability in high-temperature environments and in applications where insulating properties are essential. This ability to resist extensive wear and corrosion further solidifies their role in industries where durability under extreme conditions is crucial.

Other characteristics, such as being soft and flexible, are not typical of ceramics, as they tend to be hard and brittle. Additionally, ceramics are not commonly used as adhesives, and their properties do not lead to easy melting and reshaping like metals and some plastics, which can be melted and reformed. This makes the recognition of ceramics' heat resistance and durability a definitive marker of their role in manufacturing contexts.
