Which of the following statements is true regarding the properties of ceramics?

The statement that ceramics have high thermal and chemical stability is true and highlights a key property of ceramic materials. Ceramics are known for their ability to withstand high temperatures without melting or deforming, making them suitable for applications in high-temperature environments like furnace linings, aerospace components, and thermal barriers. Additionally, ceramics exhibit excellent resistance to chemical attack, meaning they do not easily corrode or react with acids and bases. This stability under adverse conditions contributes to their long service life and reliability in various engineering applications.

In contrast, ceramics are characterized by relatively poor electrical conductivity, which rules out the possibility of them being excellent electrical conductors. They also typically have high melting points rather than low ones, making them ideal for high-temperature applications. Finally, while certain ceramics can be shaped into intricate forms, they generally lack the malleability of metals, making them more challenging to form into complex shapes without specialized processing techniques.
