Umehluko phakathi kwe-silicon carbide ceramics kanye ne-silicon nitride ceramics

Emkhakheni wezinto ezithuthukisiwe,i-silicon carbide (SiC) kanye ne-silicon nitride (Si3N4) ceramicssezibe yizinhlanganisela ezimbili ezibaluleke kakhulu, ngayinye inezakhiwo ezihlukile kanye nezicelo. Ukuqonda umehluko phakathi kwalezi zibumba ezimbili kubalulekile ezimbonini ezithembele ezintweni ezisebenza kahle kakhulu. I-Shandong Zhongpeng Special Ceramics Co., Ltd. iyinkampani yobuchwepheshe obuphezulu egxile ekukhiqizweni kwezibumba ze-silicon carbide, edlala indima ebalulekile kulo mkhakha, inikeza ukuqonda okujulile ngezakhiwo kanye nezicelo zalezi zinto.

I-silicon carbide ceramics yaziwa ngobulukhuni bayo obumangalisayo kanye nokuqina kokushisa. Yakhiwe yi-silicon ne-carbon, ezihlangana ukuze zakhe inhlanganisela enokumelana nokugqwala okuhle kakhulu. Lokhu kwenza i-silicon carbide ceramics ifaneleke ukusetshenziswa ezindaweni ezinzima njengezimboni zezindiza, izimoto kanye ne-semiconductor. Ukushisa okuphezulu kwe-silicon carbide nakho kuyivumela ukuthi ikhiphe ukushisa kahle, okwenza ifanele ukusetshenziswa kokushisa okuphezulu. I-Shandong Zhongpeng Special Ceramics Co., Ltd. isebenzisa lezi zakhiwo ukukhiqiza i-silicon carbide ceramics esezingeni eliphezulu ehlangabezana nezidingo ezidingekayo zezimboni ezahlukahlukene.

Ngakolunye uhlangothi, i-silicon nitride ceramics inezakhiwo ezinhle kakhulu zemishini, okuhlanganisa amandla aphezulu nokuqina. I-Si3N4 ceramics, eyakhiwe yi-silicon ne-nitrogen, imelana kakhulu nokushaqeka kokushisa futhi ine-coefficient ephansi yokwanda kokushisa uma kuqhathaniswa ne-silicon carbide. Lokhu kwenza i-silicon nitride ceramics ibe yisinqumo esihle kakhulu sezinhlelo zokusebenza ezidinga izinto zokubekezelela izinguquko zokushisa okusheshayo, njenge-gas turbines namathuluzi okusika. Isakhiwo esiyingqayizivele se-Silicon nitride siphinde siyinike ukuqina okuhle kakhulu kokuqhekeka, okwenza kube yinto ekhethwayo yezimboni ezidinga izingxenye eziqinile.

Uma kuqhathaniswa lezi zinto ezimbili, omunye umehluko obaluleke kakhulu usezicini zazo zokushisa. I-silicon carbide ceramics ingamelana namazinga okushisa aphezulu kune-silicon nitride ceramics, okwenza ifaneleke ukusetshenziswa ezisetshenzisweni zokushisa okuphezulu kakhulu. Kodwa-ke, ikhono le-silicon nitride lokumelana nokushaqeka kokushisa liyinika inzuzo ezindaweni ezinokuguquguquka okukhulu kwezinga lokushisa. Lo mehluko ubalulekile konjiniyela nabaklami lapho bekhetha izinto zokusetshenziswa okuthile, njengoba ukukhetha izinto kungathinta kakhulu ukusebenza kanye nokuphila kwenkonzo.

Omunye umehluko omkhulu phakathi kwe-silicon carbide kanye ne-silicon nitride ceramics ukuqina kwamakhemikhali azo. I-Silicon carbide imelana kakhulu ne-oxidation futhi ingagcina izakhiwo zayo ngisho nasezindaweni zamakhemikhali ezigqwalisayo. Lokhu kuyenza ibe yindawo ekahle yokucubungula amakhemikhali kanye nezicelo zokukhiqiza i-semiconductor. Ngokuphambene nalokho, i-silicon nitride ceramics, yize izinzile ngamakhemikhali, ingase ingasebenzi kahle ezindaweni ezithile ezigqwalisayo. Ukuqonda lezi zakhiwo zamakhemikhali kubalulekile ezimbonini ezisebenza ezimweni ezinzima njengoba kuthinta ukukhethwa kwezinto kanye nokwakhiwa komkhiqizo.

Izinqubo zokukhiqiza ze-silicon carbide kanye ne-silicon nitride ceramics nazo ziyahluka kakhulu. I-silicon carbide ceramics ngokuvamile ikhiqizwa ngokusinta, inqubo ehilela ukushisa izinto ezingeni lokushisa elingaphansi kwephuzu lokuncibilika kwazo ukuze kufezwe ukuqina. Le ndlela ingakhiqiza izimo eziyinkimbinkimbi kanye nezingxenye ezinobukhulu obuphezulu. Ngokuphambene nalokho, i-silicon nitride ceramics ngokuvamile ikhiqizwa kusetshenziswa inhlanganisela yokucubungula i-powder kanye namasu okusinta, okuhlanganisa ukucindezela okushisa noma ukubopha kokusabela. Lokhu kwehluka kwezinqubo zokukhiqiza kungathinta izakhiwo zokugcina ze-ceramic, okuhlanganisa isakhiwo sayo esincane kanye nezakhiwo zemishini.

Ngokuphathelene nezindleko, izitsha zobumba ze-silicon carbide zivame ukubiza kakhulu kunezitsha zobumba ze-silicon nitride ngenxa yezinto zokusetshenziswa kanye nobuchwepheshe bokucubungula. Kodwa-ke, ukusebenza kwesikhathi eside kanye nokuqina kwe-silicon carbide kungathethelela ukutshalwa kwezimali kokuqala okuphezulu, ikakhulukazi ezicelweni lapho ukwehluleka kungabangela khona izingozi ezinkulu zesikhathi sokungasebenzi noma zokuphepha. I-Shandong Zhongpeng Special Ceramics Co., Ltd. igxile ekuhlinzekeni ngezixazululo ezingabizi kakhulu ngaphandle kokubeka engcupheni ikhwalithi, iqinisekisa ukuthi amakhasimende athola inani elihle kakhulu lokutshalwa kwezimali kwawo kuzitsha zobumba ze-silicon carbide.

Ngamafuphi, umehluko phakathi kwe-silicon carbide ceramics kanye ne-silicon nitride ceramics ubalulekile futhi ungathinta kakhulu ukusetshenziswa kwazo kuzo zonke izimboni ezahlukahlukene. I-Silicon carbide ihamba phambili ezindaweni ezinokushisa okuphezulu kanye nezindawo ezibola ngamakhemikhali, kuyilapho i-silicon nitride ibonisa ukuqina okuhle kakhulu kanye nokumelana nokushaqeka kokushisa. Ukuqonda lo mehluko kubalulekile konjiniyela nabakhiqizi lapho bekhetha izinto zokusetshenziswa ezithile. Njengomkhiqizi ohamba phambili we-silicon carbide ceramics, i-Shandong Zhongpeng Special Ceramics Co., Ltd. izibophezele ekuthuthukiseni insimu ye-ceramics ethuthukisiwe, ihlinzeka ngemikhiqizo esezingeni eliphezulu ehlangabezana nezidingo ezishintshayo zemboni yanamuhla. Ngokusebenzisa izakhiwo ezihlukile ze-silicon carbide kanye ne-silicon nitride, izinkampani zingenza ngcono imiklamo yazo futhi zithuthukise ukusebenza kwemikhiqizo yazo, ekugcineni kwandise ukusebenza kahle kanye nokuthembeka kwemisebenzi yazo.
