Seramiiki eriri bụ omenala thermal mkpuchi ihe n'ọtụtụ ebe na ụlọ ọrụ dị ka metallurgy, ígwè, ngwá electronic, ceramics, iko, chemical, automotive, ewu, ìhè ụlọ ọrụ, agha shipbuilding, na aerospace.Depending na Ọdịdị na mejupụtara, seramiiki eriri nwere ike categorized n'ime isi ụdị: iko steeti (amorphous) fibers na polycstalline fiber.
1.The mmepụta usoro maka iko steeti eriri.

2 Polycrystalline fiber mmepụta usoro
Enwere ụzọ abụọ mmepụta nke polycrystallineeriri seramiiki: colloid usoro na precursor usoro.
Colloidal usoro: mee soluble aluminum salts, silicon salts, wdg n'ime a colloidal ngwọta na a ụfọdụ viscosity, na ngwọta iyi na-guzobere n'ime emep uta eri site na-afụ site abịakọrọ ikuku ma ọ bụ spun site centrifugal disk, wee ghọọ aluminum-silicon oxide kristal emep uta eri site elu okpomọkụ okpomọkụ ọgwụgwọ.
Usoro nke mbụ: Mee nnu aluminom soluble na nnu silicon ka ọ bụrụ ngwọta colloidal nke nwere ụfọdụ viscosity, banye na ngwọta colloidal nke ọma na precursor (eriri organic gbasaa), wee mee ọgwụgwọ okpomọkụ ka ọ ghọọ aluminum-silicon oxide crystal fiber.
