What is the production process of ceramic fiber products and how does it work?

The production process of ceramic fiber products involves several key steps. Initially, raw materials such as kaolin, alumina, and silica are mixed and milled to create a homogenous slurry. This slurry is then fed into a spinning process where it is extruded through small holes to form fibers. The fibers are then passed through a furnace where they are heated to high temperatures, causing them to sinter and become rigid. During this process, the organic binders burn off, leaving behind a structure of inorganic material. The resulting ceramic fibers are collected, cooled, and may be further processed into various forms such as blankets, boards, or modules depending on their intended use. The high-temperature resistance and insulating properties of ceramic fibers are due to their low thermal conductivity and the presence of amorphous structures that prevent heat transfer.
