Ii-ceramics ze-Si3N4, ezenziwe nge-silicon kunye ne-nitrogen, zixhathisa ngokukodwa ukutshitshiswa kwe-thermal kwaye zine-coefficient ephantsi yokwandiswa kwe-thermal xa kuthelekiswa ne-silicon carbide. Oku kwenza i-silicon nitride ceramics ibe lolona khetho lubalaseleyo kwizicelo ezifuna izixhobo zokumelana nokutshintsha kobushushu obukhawulezayo, njengeeinjini zegesi kunye nezixhobo zokusika. I-microstructure ekhethekileyo ye-Silicon nitride ikwanika ukomelela okugqwesileyo kokwaphuka, kuyenza ibe yinto ekhethwayo kumashishini afuna izinto ezihlala ixesha elide.

Xa uthelekisa ezi zixhobo zimbini, enye yezona zinto zihluke kakhulu kwiimpawu zabo ze-thermal. Iiseramics ze-silicon carbide zinokumelana namaqondo obushushu aphezulu kune-silicon nitride ceramics, izenza zilungele ukusetyenziswa kwizicelo zobushushu obuphezulu kakhulu. Nangona kunjalo, ukukwazi kwe-silicon nitride ukumelana nomothuko we-thermal inika inzuzo kwindawo enokuguquguquka okukhulu kobushushu. Lo mahluko ubalulekile kwiinjineli kunye nabaqulunqi xa bekhetha izinto eziphathekayo kwisicelo esithile, njengoko ukukhethwa kwezinto eziphathekayo kunokuchaphazela kakhulu ukusebenza kunye nobomi benkonzo.

Omnye umahluko omkhulu phakathi kwe-silicon carbide kunye ne-silicon nitride ceramics kukuzinza kweekhemikhali. I-Silicon carbide ixhathisa kakhulu kwi-oxidation kwaye inokugcina iimpawu zayo nakwiindawo zemichiza ezonakalisayo. Oku kuyenza ilungele ukusetyenzwa kweekhemikhali kunye nezicelo zokwenziwa kwe-semiconductor. Ngokwahlukileyo, iiseramikhi ze-silicon nitride, ngelixa zizinzile ngokwekhemikhali, zisenokungasebenzi kakuhle kwiindawo ezithile ezidlekayo. Ukuqonda ezi mpawu zemichiza kubalulekile kumashishini asebenza kwiimeko ezinzima njengoko kuchaphazela ukukhethwa kwezinto kunye noyilo lwemveliso.

Iinkqubo zokwenziwa kwe-silicon carbide kunye ne-silicon nitride ceramics nazo ziyahluka kakhulu. I-silicon carbide ceramics iveliswa ngokuqhelekileyo ngokutshisa, inkqubo ebandakanya ukufudumeza izinto kwiqondo lokushisa elingaphantsi kwendawo yokunyibilika ukuze kufezekiswe ukuxinana. Le ndlela inokuvelisa iimilo ezinzima kunye namacandelo aphezulu. Ngokwahlukileyo, iiseramikhi ze-silicon nitride ziveliswa kusetyenziswa indibaniselwano yomgubo wokusetyenzwa kunye neendlela zokuthambisa, kubandakanya ukucinezela okushushu okanye ukuhlangana kwento. Ezi zintlukwano kwiinkqubo zokuvelisa zinokuchaphazela iipropati zokugqibela ze-ceramic, kubandakanywa ne-microstructure yayo kunye neempawu zomatshini.

Ngokwexabiso, iiseramics ze-silicon carbide zithande ukubiza kakhulu kune-silicon nitride ceramics ngenxa yemathiriyeli ekrwada kunye netekhnoloji yokucubungula. Nangona kunjalo, ukusebenza kwexesha elide kunye nokuqina kwe-silicon carbide kunokulungelelanisa utyalo-mali oluphezulu lokuqala, ngakumbi kwizicelo apho ukusilela kunokubangela ukwehla okukhulu okanye umngcipheko wokhuseleko. I-Shandong Zhongpeng Special Ceramics Co., Ltd. igxile ekuboneleleni izisombululo ezingabizi kakhulu ngaphandle kokunciphisa umgangatho, ukuqinisekisa ukuba abathengi bafumana elona xabiso lilungileyo lokutyala imali yabo kwi-silicon carbide ceramics.

Ngamafutshane, umahluko phakathi kweeseramics ze-silicon carbide kunye ne-silicon nitride ceramics zibalulekile kwaye zinokuchaphazela kakhulu usetyenziso lwazo kumashishini ahlukeneyo.
