An overview of refractory ceramic fibers | Thermal ...

Refractory ceramic fibers are synthetic fibers produced by the melting and blowing or spinning of calcined kaolin clay or a combination of alumina (Al2O3), silicon dioxide (SiO2), or other oxides, usually in a 50:50 weight ratio. The most common grade RCF fiber provided by most USA-based fabricators and suppliers is the "high purity" grade ...
