Classification of ceramic fibers
Thread Content
Ceramic fibers are available in 1000 degrees, 1100 degrees, 1200 degrees, and 1300 degrees. What is the basis for their classification?
Is it classified based on different fire resistance levels?
It is classified according to different operating temperatures.
Maximum temperature of the operating environment that can be sustained over a long period of time
Ceramic fibers, also known as refractory fibers, are inorganic non-metallic fiber materials. They are produced by melting ore raw materials at high temperatures and then using processes such as spraying or spinning to form the fibers. The most commonly used type in industry are aluminum silicate-based fibers, which are generally classified based on the ratio of SiO2 to Al2O3 in their composition. The higher the proportion of Al2O3, the greater the refractoriness. Refractory metal oxides such as ZrO can also be added to enhance the refractoriness.
It’s a bit like fiberglass, but the two are definitely not the same, haha
