Iikeramikhi zobugcisa zinamandla amakhulu omatshini, ukuqina, ukumelana nokunxiba, ukumelana nobushushu, kunye noxinzelelo oluphantsi. Ngokubhekiselele kwi-conductivity, yinto egqwesileyo yombane kunye ne-thermal insulator.
Emva kokutshatyalaliswa kwe-thermal, okufudumeza ngokukhawuleza okubangela ukuba i-ceramic yande, i-ceramic inokusingatha utshintsho lweqondo lokushisa ngokukhawuleza ngaphandle kokuqhekeka, ukuphuka, okanye ukulahlekelwa amandla ayo omatshini.
Umothuko we-Thermal, okwaziwa ngokuba yi "thermal collapse," kukuqhekeka kwayo nayiphi na into eqinileyo ebangelwa kukutshintsha kobushushu ngequbuliso. Utshintsho lobushushu lunokuba lubi okanye lube luhle, kodwa kufuneka luphawuleke kuyo nayiphi na imeko.
Uxinzelelo lomatshini lwenzeka phakathi komphandle wemathiriyeli (iqokobhe) kunye nangaphakathi (umbindi) njengoko ishushu okanye ipholisa ngokukhawuleza ngaphandle kunangaphakathi.
Izinto eziphathekayo zonakaliswa ngokungenakulungiseka xa umahluko wobushushu udlula umda othile. Ezi zinto zilandelayo zinempembelelo kweli xabiso libalulekileyo lobushushu:
Ukutshintsha enye okanye ngaphezulu kwezi zinto zihlala ziphucula ukusebenza, kodwa njengazo zonke izicelo ze-ceramic, ukothuka kwe-thermal yinxalenye enye ye-equation, kwaye naluphi na utshintsho kufuneka lucingelwe kumxholo wazo zonke iimfuno zokusebenza.
Xa uyila nayiphi na imveliso ye-ceramic, kubalulekile ukuqwalasela imfuno epheleleyo kwaye rhoqo ufumane eyona mveliso isebenzayo.
Umothuko wobushushu ngoyena nobangela uphambili wokusilela kwizicelo zobushushu obuphezulu. Yenziwe ngamacandelo amathathu: ukwanda kwe-thermal, conductivity ye-thermal, kunye namandla. Ukutshintsha kwamaqondo obushushu okukhawulezayo, ukuhla nokunyuka, kubangela ukwahluka kobushushu ngaphakathi kwendawo, kufana nokuqhekeka okubangelwa kukuhlikihla igaqa lomkhenkce kwiglasi eshushu. Ngenxa yokwandiswa nokucutheka okwahlukeneyo, ukunyakaza kubangela ukuqhekeka kunye nokusilela.
Azikho izisombululo ezilula kwingxaki yokothuka kwe-thermal, kodwa ezi ngcebiso zilandelayo zinokuba luncedo:
Khetha ibakala lemathiriyeli elineempawu ezithile zokothuka kwe-thermal kodwa lihlangabezana neemfuno zesicelo. I-silicon carbides ibalasele. Iimveliso ezisekelwe kwi-alumina azinqweneleki kangako, kodwa zinokuphuculwa ngokuyila ngokufanelekileyo. Iimveliso zePorous zingcono kunezo zingangenwayo kuba ziyakwazi ukumelana notshintsho olukhulu lobushushu.
Iimveliso ezinodonga olubhityileyo zigqwesa ezo zineendonga ezishinyeneyo. Kwakhona, thintela utshintsho olukhulu kwindawo yonke. Amacandelo angakhethwa ngenxa yokuba anobunzima obuncinci kunye noyilo oluqhekekileyo olunciphisa uxinzelelo.
Kuphephe ukusebenzisa iikona ezibukhali, njengoko ezi ziindawo eziphambili zokuqhekeka. Kuphephe ukubeka uxinzelelo kwi-ceramic. Amacandelo anokuthi ayilwe ukuba agxininiswe kwangaphambili ukunceda ukunciphisa le ngxaki. Phonononga inkqubo yesicelo ukubona ukuba kuyenzeka na ukunika utshintsho oluthe chu kancinci lobushushu, njengokufudumeza i-ceramic yangaphambili okanye ukucothisa isantya sotshintsho lobushushu.
