I-Ceramic fibre iyisisetshenziswa esivamile sokushisa okushisayo esisetshenziswa kabanzi ezimbonini ezifana ne-metallurgy, imishini, i-electronics, i-ceramics, ingilazi, amakhemikhali, izimoto, ukwakhiwa, imboni yokukhanya, ukwakhiwa kwemikhumbi yezempi, kanye ne-aerospace.Ngokuya ngesakhiwo nokubunjwa, i-ceramic fibre ingahlukaniswa ngezinhlobo ezinkulu: i-glass state (amorphous) fibers kanye ne-polycrystalsline (crystalline).
1.Indlela yokukhiqiza ye-glass state fibers.
Indlela yokukhiqiza yengilazi ye-ceramic fibers ihlanganisa ukuncibilika kwezinto ezingavuthiwe esithandweni sokumelana nogesi. Impahla encibilikisiwe enezinga eliphezulu lokushisa igeleza iphumele esigubhuni esizungezayo esinesivinini esikhulu se-multi-roller centrifuge. Amandla amaphakathi wesigubhu esizungezayo enza into encibilikisiwe yezinga eliphezulu lokushisa ibe into emise okwefayibha. Impahla encibilikisiwe enezinga lokushisa eliphezulu ingenziwa futhi ibe into emise okwefayibha ngokuphephethwa ngokugeleza komoya okunesivinini esikhulu.
2 Indlela yokukhiqiza i-polycrystalline fiber
Kunezindlela ezimbili zokukhiqiza ze-polycrystallineimicu ye-ceramic: indlela ye-colloid nendlela eyandulelayo.
Indlela ye-Colloidal: yenza usawoti we-aluminium oncibilikayo, usawoti we-silicon, njll. ube yisixazululo se-colloidal esine-viscosity ethile, futhi umfudlana wesixazululo ukwakheka ube imicu ngokushaywa umoya ocindezelwe noma ukuphothwa ngediski eyi-centrifugal, bese uguqulwa ube imicu yamakristalu e-aluminium-silicon oxide ngokusebenzisa ukwelashwa kokushisa okunokushisa okuphezulu.
Indlela ye-Precursor: Yenza i-aluminium encibilikayo kasawoti kanye ne-silicon kasawoti ibe yikhambi le-colloidal eline-viscosity ethile, donsa isixazululo se-colloidal ngokulinganayo ngesandulela (i-organic fiber enwetshiwe), bese uphatha ukwelashwa kokushisa ukuze uguqule kube i-aluminium-silicon oxide crystal fiber.
