How is ceramic fiber processed?

Ceramic fiber processing involves several key steps. First, raw materials like kaolin, alumina, and silica are mixed and ground. The mixture is then extruded or blown to form fibers. These fibers are heated in a furnace to remove organics and create a ceramic structure, a process known as calcination. The resulting fibers are cooled, and their properties are tested to ensure they meet the required specifications. Finally, the fibers are cut to the desired length and packaged for use in various applications such as insulation, filtration, and thermal protection.
