What material is NOT typically used in boiler construction?

• A. Steel
• B. Aluminum
• C. Ceramic
• D. Various alloys

Answer: (C)

In boiler construction, ceramic materials are generally not utilized due to their brittleness and inability to withstand the high temperatures and pressures typically encountered in boiler environments. Ceramics, while great for insulation and some specialized applications, lack the necessary mechanical properties such as ductility and toughness that metals provide, making them unsuitable for the structural integrity required in boiler systems. On the other hand, steel, various alloys, and aluminum are all common materials in boiler construction. Steel is favored for its strength and durability, various alloys are often used to enhance resistance to corrosion and temperature effects, and aluminum, while less common, is utilized in some applications due to its lightweight and corrosion-resistant properties.
