Description of Ceramic Fiber
Ceramic fiber is produced from high purity aluminosilicate material through a strictly controlled high-temperature furnace melting and fiberizing process. Ceramic fiber products are white and odorless, which is suitable for high-temperature applications up to 2300°F. Due to the resistance to high temperatures, good thermal stability, and significant energy-saving effects, ceramic fibers are gradually replacing traditional refractory brick refractories.
Advantages of Ceramic Fiber
- Faster temperature cycling
- Lower heat storage
- Lower fuel costs
- Increased productivity
- Lower installation cost
- Easier repairs
- Resistance to thermal shock
