Final answer:
A fire brick is made of fire clay and used for lining furnaces and fireplaces. (option 1)
Step-by-step explanation:
A fire brick is made of fire clay and is specifically designed for use in high-temperature environments such as lining furnaces and fireplaces. Fire clay, a type of clay that can withstand intense heat, is the primary material for manufacturing fire bricks. These bricks are dense, durable, and capable of withstanding the thermal stress and rapid temperature changes that occur in applications like furnaces and fireplaces.
In furnaces, fire bricks form linings that protect the surrounding structures from extreme heat, ensuring efficient and safe operation. Similarly, fireplaces, create a barrier that can withstand the intense heat generated during combustion, enhancing both safety and longevity. In conclusion, the utilization of fire bricks, composed of fire clay, is essential for maintaining the structural integrity and performance of equipment and structures exposed to high temperatures.
The correct option is "Fire Brick." It is essential to use materials like fire bricks in settings where exposure to high temperatures is common, as they provide effective insulation and protection against heat-related damage. Fire bricks play a crucial role in maintaining the structural integrity of furnaces and fireplaces by withstanding extreme temperatures, making them a preferred choice for such applications.
