THE PRODUCTION, PROPERTIES AND USE OF CERAMIC FIBRES

Öz

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. Structural properties such us strrnxtli imrl morhrles may be retnined to 1200-1400'C in inert und osirliziiig ntmospheres. Compnrrrd with orj!rriiicfibres, ceruniic fibres hnut! hr~h elnstic inodolr: on11 low clonjiotions lo brr!rrk Tllase if combined wlrh lzi~li filnmn~t rlirrrnctsr am /r,ad ro low hrw- -. hing strengths and difficulty in hnndling.
