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 (Al 2 O 3) silicon dioxide (SiO 2) 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

ITAS Roto-concentratorsFives in Combustion
Rotating concentrators are used in Volatile Organic Compounds (VOCs) treatment processes when the VOCs concentration is under 1 g/Nm3 VOC. The accumulated VOCs are released to a small hot air stream and can be treated in a smaller post-combustion system.

Ceramic matrix compositeWikipedia
Ceramic fibers in CMCs can have a polycrystalline structure as in conventional ceramics. They can also be amorphous or have inhomogeneous chemical composition which develops upon pyrolysis of organic precursors.The high process temperatures required for making CMCs preclude the use of organic metallic or glass fibers.Only fibers stable at temperatures above 1 000 °C (1 800 °F) can be used
