Which of the following is a common ceramic application?

• A. Metal cutting tools.
• B. Bricks and tiles, glass, and ceramic engine components.
• C. Textile fibers.
• D. Electronic semiconductors.

Answer: (C)

Ceramics are hard, heat-stable, and chemically inert, so they excel in uses that demand durability and resistance to heat and wear. That’s why bricks and tiles, glass, and ceramic engine components are classic ceramic applications: bricks and tiles rely on fired ceramic materials to provide rugged, weatherproof building surfaces; glass is a quintessential ceramic product with excellent hardness and chemical stability; and ceramic engine components are chosen for their ability to perform at high temperatures and resist wear in demanding engine environments. Textile fibers, on the other hand, come from polymers or natural materials and are valued for flexibility and softness rather than high hardness or heat resistance, so they aren’t typical ceramic applications. While ceramics do appear in electronics as insulating or protective materials, the most representative everyday ceramic uses stay with bricks, tiles, glass, and engine components.
