Yes, ceramic fibers are widely used in construction and manufacturing processes due to their high temperature resistance, strength, and insulating properties. They are utilized in various applications such as thermal insulation, fireproofing, and reinforcement in composite materials. In construction, they can be found in fire-resistant coatings and insulation for pipes and boilers. In manufacturing, they are used in the production of high-temperature furnaces, kilns, and as a component in certain types of high-performance plastics and ceramics.
