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

Emkhakheni wezinto ezithuthukisiwe,i-silicon carbide (SiC) kanye ne-silicon nitride (Si3N4) ceramicsabe yizinhlanganisela ezimbili ezibaluleke kakhulu, ngayinye enezakhiwo ezihlukile kanye nezicelo. Ukuqonda umehluko phakathi kwalezi zitsha zobumba ezimbili kubalulekile ezimbonini ezithembele ezintweni ezisebenza kahle kakhulu. I-Shandong Zhongpeng Special Ceramics Co., Ltd. iyibhizinisi lobuchwepheshe obuphezulu elisebenza ngokukhethekile ekukhiqizeni izitsha zobumba ze-silicon carbide, edlala indima ebaluleke kakhulu kulo mkhakha, ihlinzeka ngemininingwane ejulile mayelana nezakhiwo kanye nokusetshenziswa kwalezi zinto.

Izitsha zobumba ze-silicon carbide zaziwa ngobulukhuni bazo obungavamile kanye nokuzinza kokushisa. Aqukethe i-silicon nekhabhoni, ehlanganayo yakhe inhlanganisela enokuqina okuhle kakhulu nokungagqwali. Lokhu kwenza i-silicon carbide ceramics ilungele ukusetshenziswa ezindaweni ezinokhahlo njengezimboni ze-aerospace, zezimoto kanye ne-semiconductor. Ukushisa okuphezulu kwe-silicon carbide nakho kuyivumela ukuthi ikhiphe ukushisa kahle, iyenze ilungele ukusetshenziswa okunokushisa okuphezulu. I-Shandong Zhongpeng Special Ceramics Co., Ltd. isebenzisa lezi zakhiwo ukukhiqiza izitsha ze-silicon carbide ceramics ezihlangabezana nezidingo ezidingekayo zezimboni ezihlukahlukene.

Ngakolunye uhlangothi, izitsha zobumba ze-silicon nitride, zinezakhiwo ezinhle kakhulu zemishini, kufaka phakathi amandla aphezulu kanye nokuqina. I-ceramics ye-Si3N4, eyakhiwe nge-silicon ne-nitrogen, imelana ikakhulukazi nokushaqeka okushisayo futhi ine-coefficient ephansi yokwandisa okushisayo uma kuqhathaniswa ne-silicon carbide. Lokhu kwenza izitsha zobumba ze-silicon nitride zibe ukukhetha okuhle kakhulu kwezinhlelo zokusebenza ezidinga izinto zokwakha ukumelana nokushintsha kwezinga lokushisa okusheshayo, okufana nezinjini zegesi namathuluzi okusika. I-microstructure eyingqayizivele ye-Silicon nitride nayo iyinikeza ukuqina okuhle kakhulu kokuphuka, okuyenza ibe yinto yokuzikhethela ezimbonini ezidinga izingxenye ezihlala isikhathi eside.

Uma uqhathanisa lezi zinto ezimbili, umehluko obaluleke kakhulu usezicini zabo ezishisayo. Izitsha zobumba ze-silicon carbide zingamelana namazinga okushisa aphezulu kune-silicon nitride ceramics, zizenze zifanelekele ukusetshenziswa ezindaweni ezishisa kakhulu. Kodwa-ke, ikhono le-silicon nitride lokumelana nokushaqeka okushisayo liyinikeza inzuzo ezindaweni ezinokuguquguquka okukhulu kwezinga lokushisa. Lo mehluko ubalulekile konjiniyela nabaklami lapho bekhetha into yohlelo lokusebenza oluthile, njengoba ukukhethwa kwezinto kungathinta kakhulu ukusebenza nempilo yesevisi.

Omunye umehluko omkhulu phakathi kwe-silicon carbide ne-silicon nitride ceramics ukuzinza kwazo kwamakhemikhali. I-Silicon carbide imelana kakhulu ne-oxidation futhi ingagcina izakhiwo zayo ngisho nasezindaweni zamakhemikhali ezonakalisayo. Lokhu kuyenza ilungele ukucubungula amakhemikhali kanye nezicelo zokukhiqiza ze-semiconductor. Ngokuphambene, izitsha zobumba ze-silicon nitride, kuyilapho zizinzile ngokwamakhemikhali, zingase zingasebenzi kahle ezindaweni ezithile ezigqwalile. Ukuqonda lezi zakhiwo zamakhemikhali kubalulekile ezimbonini ezisebenza ngaphansi kwezimo eziyinselele njengoba kuthinta ukukhethwa kwezinto kanye nokwakheka komkhiqizo.

Izinqubo zokukhiqiza ze-silicon carbide kanye ne-silicon nitride ceramics nazo zehluka kakhulu. I-silicon carbide ceramics ivamise ukukhiqizwa nge-sintering, inqubo efaka ukushisisa okokusebenza kuzinga lokushisa elingaphansi kwendawo yokuncibilika ukuze kuzuzwe ukuminyana. Le ndlela ingakhiqiza izimo eziyinkimbinkimbi kanye nezingxenye eziphakeme kakhulu. Ngokuphambene, izitsha zobumba ze-silicon nitride ngokuvamile zikhiqizwa kusetshenziswa inhlanganisela yokucubungula impushana namasu okugcoba, okuhlanganisa ukucindezela okushisayo noma ukuhlanganisa ukusabela. Lo mehluko ezinkambisweni zokukhiqiza ungathinta izakhiwo zokugcina ze-ceramic, kufaka phakathi i-microstructure yayo kanye nezakhiwo zemishini.

Mayelana nezindleko, i-silicon carbide ceramics ivame ukubiza kakhulu kune-silicon nitride ceramics ngenxa yezinto ezingavuthiwe kanye nobuchwepheshe bokucubungula. Nokho, ukusebenza kwesikhathi eside nokuqina kwe-silicon carbide kungathethelela ukutshalwa kwezimali okuphezulu kokuqala, ikakhulukazi ezinhlelweni zokusebenza lapho ukwehluleka kungase kubangele ukwehla okukhulu kwesikhathi noma ezingozini zokuphepha. I-Shandong Zhongpeng Special Ceramics Co., Ltd. igxile ekuhlinzekeni izisombululo ezibiza izindleko ngaphandle kokuyekethisa ikhwalithi, iqinisekisa ukuthi amakhasimende athola inani elingcono kakhulu lokutshala kwawo kuzitsha zobumba ze-silicon carbide.

Kafushane, umehluko phakathi kwezitsha ze-silicon carbide ceramics zibalulekile futhi zingaba nomthelela omkhulu ekusetshenzisweni kwazo kuzo zonke izimboni ezihlukahlukene. I-silicon carbide ihamba phambili ekushiseni okuphezulu nasezindaweni ezidla amakhemikhali, kuyilapho i-silicon nitride ibonisa ukuqina okuhle kakhulu nokumelana nokushaqeka okushisayo. Ukuqonda lo mehluko kubalulekile konjiniyela nabakhiqizi lapho kukhethwa izinto zokusebenza zezinhlelo ezithile zokusebenza. Njengomkhiqizi ohamba phambili wama-silicon carbide ceramics, i-Shandong Zhongpeng Special Ceramics Co., Ltd. izibophezele ekuthuthukiseni umkhakha wezitsha zobumba ezithuthukile, ihlinzeka ngemikhiqizo yekhwalithi ephezulu ehlangabezana nezidingo eziguqukayo zemboni yesimanje. Ngokusebenzisa izakhiwo eziyingqayizivele ze-silicon carbide ne-silicon nitride, izinkampani zingakwazi ukuthuthukisa imiklamo yazo futhi zithuthukise ukusebenza kwemikhiqizo yazo, ekugcineni zikhulise ukusebenza kahle nokuthembeka kwemisebenzi yazo.
