NCIt synonyms : Respirable Size Ceramic Fiber; Mineral Wool;
NCIt definition : Most ceramic fibers are white to cream colored and are typically composed of alumina,
silica and other metal oxides. Ceramic fibers are able to withstand high temperatures
and are used as insulation material, primarily for lining furnaces and kilns. These
fibers are the primary replacement for asbestos. Exposure to ceramic fiber irritates
the skin and upper-respiratory tract. Respirable ceramic fiber is reasonably anticipated
to be a human carcinogen. (NCI05);
