Ceramic Fiber an overview | ScienceDirect Topics
Nextel 720 consists of 85 wt% alumina + 15 wt% silica. Almax fiber from Mitsui Mining Co. fiber while Saphikon is a continuous monocrystalline alumina fiber (diameter between 75 and 225 m) grown from melt by a process known as edgedefined filmfed growth process. Sometimes Saphikon fibers show undulations on the fiber surface, see Fig. 13.
