How is ceramic fiber produced?

Ceramic fiber is produced through a process that involves several key steps. Initially, raw materials such as kaolin, alumina, and silica are mixed and ground into a fine powder. This mixture is then extruded or blown into fibers using high-temperature air or steam. The fibers are subsequently passed through a furnace where they are heated to temperatures between 1,000掳C and 1,600掳C, causing them to sinter and form a glass-like structure. After sintering, the fibers are cooled, collected, and may be further processed into various forms such as blankets, boards, or modules depending on their intended use. The production process can also include the addition of binders and other chemicals to enhance the fiber's properties.
