Ceramics nre frequently defined LU inorgunic non-metnllic mnterinls, oxide or non-oxide. The mrrin cmrmics ror oxides, nitrites nnd cnrl~irles. Often they hnue thc srnne kind of npplicntions rrq silica, crirhon nntl glass fibres. Cerrunics houe higher densities than organic mnterinls but lower than metals. Ceramic fibers hnue mnny i~nique propertres compnred with organic and other fibres. Foremost is the therinrd stobility far beyond tire capabilities (~f orgrrnic onrl evrn most mrc tnl fibres.
