Product Information Sheet Fiberfrax Ceramic Fiber

Series fibers are manufactured from kaolin clay rather than high-purity alumina-silica raw materials. Since kaolin is a mined material, it may contain impurities such as Fe 2O 3, TiO 2, and Na process or by washing out the unfiberized material.

ANZAPLAN partner in High Purity Alumina (HPA) project

Feed stock for the production of the sapphire crystals is high purity alumina (Al2O3 of purities N4, N5 and N6). The traditional process for the manufacture of alumina is the Bayer process. In this process bauxite is treated with caustic soda to finally produce smelter grade alumina (SGA) which has to be refined further to obtain HPA and large quantities of a toxic waste product called red mud.
