Refractory ceramic fibers Fiber characteristics
· Abstract. Refractory ceramic fibers (RCFs) are amorphous fibers that belong to a class of materials termed synthetic vitreous fibers (SVFs) also called man-made mineral fibers (MMMFs) which includes alkaline earth silicate wool glass wool rock (stone) wool slag wool and special-purpose glass fibers. RCFs are more durable and biopersistent

Ceramic Fibers (Respirable Size) Use
· Ceramic fibers comprise a wide range of amorphous or crystalline synthetic mineral fibers characterized by their refractory properties (i.e. stability at high temperatures) (IARC 1988). They typically are made of alumina silica and other metal oxides or less commonly of nonoxide materials such as silicon carbide. Most ceramic fibers are composed of alumina and silica in an approximate 50/50 mix-ture. By definition monoxide ceramics such as alumina and zirco-nia are composed of at least 80 of one oxide they generally contain 90 or more of the base oxide and specialty products may contain virtually 100 . Nonoxide specialty ceramic fibers such as silicon carbide silicon nitride and boron nitride also have been produced. Because there are several types of ceramic fibers such fibers exhibit a range of chemical and physical properties. Most ceramic fibers
