The ule okpomọkụ nke kpo oku waya shrinkage uru ≤3% bụ na-aga n'ihu ọrụ okpomọkụ nke seramiiki eriri ngwaahịa.N'oge okpomọkụ a, eriri seramiiki amorphous na-egbuke egbuke ma na-eto nwayọọ nwayọọ, na njirimara eriri ahụ kwụsiri ike ma na-agbanwe.
Ịkpọ oku waya shrinkage uru ≤4% ule okpomọkụ maka seramiiki eriri ngwaahịa na-eji okpomọkụ.
3 Thermal conductivity
Thermal conductivity bụ ụdị anụ ahụ nke ihe onwunwe, nke bụ index nke thermal mkpuchi ihe onwunwe nke seramiiki eriri.
Na-adabere na nhazi nke ngwaahịa fiber seramiiki, njupụta olu, okpomọkụ, ikuku ọkụ, iru mmiri na ihe ndị ọzọ.
Ceramic fiber bụ ngwakọta nke eriri siri ike na ikuku nwere porosity nke 93%.Ọnụ ọgụgụ dị ukwuu nke ikuku na obere okpomọkụ okpomọkụ na-ejupụta na pores, na-ebibikwa usoro netwọk na-aga n'ihu nke ụmụ irighiri ihe siri ike, ka e wee nweta ezigbo arụmọrụ adiabatic.Na nta nke pore dayameta, tinyere ntụziaka nke okpomọkụ eruba site siri ike eriri kewara n'ime a mechiri emechi ala nke ọnụ ọgụgụ nke pores, mma thermal mkpuchi arụmọrụ nke seramiiki eriri.
