Iingubo zefayibha yeseramikhi zizinto ezidumileyo zokukhusela ubushushu ezaziwa ngokuba neempawu zazo ezibalaseleyo zobushushu. Zisetyenziswa kakhulu kumashishini ahlukeneyo, kuquka i-aerospace, ukuveliswa kombane, kunye nemveliso, ngenxa yezakhono zazo eziphezulu. Enye yezinto ezibalulekileyo ezinegalelo ekusebenzeni kwazo kukungaqhubi kakuhle kobushushu.
Ukuqhuba ubushushu buyindlela yokulinganisa amandla ezinto zokuqhuba ubushushu. Kunjengobungakanani bobushushu obuhamba kwindawo yeyunithi yezinto kwiyunithi yexesha ngomahluko wobushushu ngeyunithi. Ngamazwi alula, ukuqhuba ubushushu bumisela ukuba izinto zingawudlulisa njani amandla obushushu.
Iingubo zefayibha yeseramikhi zine-thermal conductivity ephantsi kakhulu, nto leyo efunekayo ekufakeni i-insulation. U-thermal conductivity ophantsi kwezi ngubo ubangelwa kakhulu bulwakhiwo olulodwa lweefayibha zeseramikhi.
Iifayibha zeseramikhi zenziwe ngomxube wezinto ze-alumina kunye ne-silica, ezisebenzisa ubushushu obuphantsi. Ezi fayibha zincinci kwaye zikhaphukhaphu, zinomlinganiselo ophezulu, nto leyo ethetha ukuba ubude bazo bukhulu kakhulu kunobubanzi bazo. Olu lwakhiwo luvumela umoya omninzi kunye nezithuba ngaphakathi kwengubo, ezisebenza njengemiqobo yobushushu kwaye zithintele ukudluliselwa kobushushu.
Ukuqhuba kobushushu kwengubo yefayibha yeseramikhi kunokwahluka ngokuxhomekeke kuhlobo oluthile kunye nokwakheka kwengubo, kunye noxinano lwayo. Ngokubanzi, ukuqhuba kobushushu kwengubo yefayibha yeseramikhi kususela kwi-0.035 ukuya kwi-0.08 W/m·K. Olu luhlu lubonisa ukuba iingubo zefayibha yeseramikhi zineempawu ezibalaseleyo zokukhusela, njengoko zine-conductivity ephantsi kakhulu yobushushu xa kuthelekiswa nezinye izinto zokukhusela eziqhelekileyo njengefiberglass okanye uboya belitye.
Ukuqhuba okuphantsi kobushushuiingubo zefayibha yeseramikhiInika iingenelo ezininzi kwizicelo. Okokuqala, inceda ekunciphiseni ukulahleka okanye ukuzuza kobushushu, iqinisekisa ukusebenza kakuhle kwamandla kwiinkqubo zoshishino nakwizakhiwo. Ngokuthintela ukudluliselwa kobushushu, iingubo zefayibha yeseramikhi zinceda ekugcineni imeko-bume izinzile nelawulwayo inciphisa amandla afunekayo ukufudumeza okanye ukupholisa indawo.
Ukongeza, ukuhanjiswa kobushushu obuphantsi kweengubo zeseramikhi kunceda ekumelaneni kwazo kakuhle nobushushu obuphezulu. Ezi ngubo zinokumelana nobushushu obufikelela kuma-2300°F (1260)°C) ngelixa zigcina ulwakhiwo lwazo kunye neempawu zokukhusela. Oku kwenza zilungele ukusetyenziswa kwiindawo ezinobushushu obuphezulu, njengee-linings ze-oven okanye i-oven.
