Ii-Si3N4 ceramics, ezenziwe nge-silicon kunye ne-nitrogen, ziyakwazi ukumelana noxinzelelo lobushushu kwaye zinomlinganiselo ophantsi wokwanda kobushushu xa kuthelekiswa ne-silicon carbide. Oku kwenza ii-silicon nitride ceramics zibe lukhetho oluhle kakhulu kwizicelo ezifuna izixhobo zokumelana notshintsho olukhawulezileyo lobushushu, njengee-turbines zegesi kunye nezixhobo zokusika. Ulwakhiwo olukhethekileyo lwe-silicon nitride lukwayinika ukuqina kwayo okugqwesileyo kokuqhekeka, okwenza ukuba ibe yinto ekhethwayo kumashishini afuna izinto ezihlala ixesha elide.
Xa kuthelekiswa ezi zinto zimbini, omnye umahluko obalulekileyo ukwiimpawu zazo zobushushu. Iiceramics zeSilicon carbide zinokunyamezela amaqondo obushushu aphezulu kuneeceramics zeSilicon nitride, nto leyo eyenza zifaneleke ukusetyenziswa kwiindawo ezinobushushu obuphezulu kakhulu. Nangona kunjalo, amandla eSilicon nitride okumelana nobushushu ayinika ithuba kwiindawo ezinokuguquguquka okukhulu kobushushu. Olu mahluko lubalulekile kwiinjineli kunye nabayili xa bekhetha izinto zesicelo esithile, njengoko ukukhetha izinto kunokuchaphazela kakhulu ukusebenza kunye nobomi benkonzo.
Omnye umahluko omkhulu phakathi kwe-silicon carbide kunye ne-silicon nitride ceramics kukuzinza kwazo ngokweekhemikhali. I-Silicon carbide iyakwazi ukumelana kakhulu ne-oxidation kwaye inokugcina iipropati zayo nakwiindawo zeekhemikhali ezirhabaxa. Oku kuyenza ifaneleke kakhulu ekucutshungulweni kweekhemikhali kunye nezicelo zokwenza i-semiconductor. Ngokwahlukileyo koko, ii-silicon nitride ceramics, nangona zizinzile ngokweekhemikhali, zisenokungasebenzi kakuhle kwiindawo ezithile ezirhabaxa. Ukuqonda ezi mpawu zeekhemikhali kubalulekile kumashishini asebenza kwiimeko ezinzima njengoko kuchaphazela ukukhethwa kwezinto kunye noyilo lwemveliso.
Iinkqubo zokuvelisa i-silicon carbide kunye ne-silicon nitride ceramics nazo zahlukile kakhulu. Ii-silicon carbide ceramics zihlala ziveliswa ngokusinta, inkqubo equka ukufudumeza izinto ukuya kubushushu obungaphantsi kwenqanaba lokunyibilika kwazo ukuze kufezekiswe uxinano. Le ndlela inokuvelisa iimilo ezintsonkothileyo kunye nezinto ezinoxinano oluphezulu. Ngokwahlukileyo koko, ii-silicon nitride ceramics zihlala ziveliswa kusetyenziswa indibaniselwano yeendlela zokucubungula ipowder kunye nokusinta, kubandakanya ukucinezela okutshisayo okanye ukubophelelana kwe-reaction. Olu mahluko kwiinkqubo zokuvelisa lunokuchaphazela iipropati zokugqibela ze-ceramic, kubandakanya isakhiwo sayo esincinci kunye neempawu zoomatshini.
Ngokuphathelele iindleko, ii-silicon carbide ceramics zidla ngokubiza kakhulu kune-silicon nitride ceramics ngenxa yezinto eziluhlaza kunye netekhnoloji yokucubungula. Nangona kunjalo, ukusebenza kwexesha elide kunye nokuqina kwe-silicon carbide kunokuthethelela utyalo-mali oluphezulu lokuqala, ngakumbi kwizicelo apho ukungaphumeleli kunokubangela umngcipheko omkhulu wexesha lokungasebenzi okanye ukhuseleko. I-Shandong Zhongpeng Special Ceramics Co., Ltd. igxile ekuboneleleni ngezisombululo ezingabizi kakhulu ngaphandle kokubeka umgangatho esichengeni, iqinisekisa ukuba abathengi bafumana ixabiso elifanelekileyo lotyalo-mali lwabo kwi-silicon carbide ceramics.
