1. Isetshenziswa ezintweni eziyigugu
Embonini yamatshe ayigugu, i-silicon carbide yaziwa nangokuthi "moissanite". Izinto ezivame ukubonakala emakethe ziyi-moissanite eyenziwe ngokwenziwa, kuyilapho i-moissanite yemvelo iyivelakancane kakhulu, ayivamile kangangokuthi yavela kuphela kuma-meteorite craters eminyakeni engu-50000 edlule.
2, Izicelo zezimboni zendabuko
Emkhakheni wezimboni wendabuko, i-silicon carbide isetshenziswa ngokuyinhloko njengento ephikisayo, ithuluzi eli-abrasive, nezinto ze-metallurgical, ezizohlaziywa ngokwehlukana embhalweni olandelayo.
(1) Imikhiqizo yokumelana nezinga lokushisa eliphezulu:
Kusetshenziswa izici zokumelana nokugqwala, ukumelana nokushisa okuphezulu, amandla aphezulu, ukuguquguquka okuhle kokushisa, kanye nokumelana nomthelela wezinto ze-silicon carbide, zingasetshenziselwa izingqimba zomlilo ezincibilikayo ezincibilikayo, izingxenye zesithando somlilo esishisa kakhulu, amapuleti e-silicon carbide, amapuleti omugqa, izisekelo, namaladi. Ngakolunye uhlangothi, izinto zokushisa ezingaqondile ezinokushisa okuphezulu zingasetshenziswa embonini yokuncibilikisa insimbi engeyona i-ferrous, njengeziko lokuncibilikisa mpo, amapuleti e-arc weziko le-zinc powder, amashubhu okuvikela i-thermocouple, njll; Isetshenziselwa ukukhiqiza izinto ezithuthukisiwe ze-silicon carbide ceramic ezingagugi, zimelana nokugqwala, futhi zimelana nezinga lokushisa eliphezulu; Ingase futhi isetshenziselwe ukwenza imibhobho ye-rocket, izindwani ze-turbine yegesi, njll Ngaphezu kwalokho, i-silicon carbide nayo ingenye yezinto ezifanelekile zokushisa amanzi elanga emigwaqweni emikhulu, izindiza zezindiza, njll. Ngakho-ke, i-silicon carbide nayo inegama elivamile elithi "isihlabathi esiphikisayo", okuyinto, nakuba ivame kakhulu, ibonisa ngokugcwele izakhiwo zayo zokuphikisa.
(2) Imikhiqizo ekwazi ukumelana nokugqwala kanye ne-corrosion:
Ikakhulukazi ngenxa yokuthi i-silicon carbide inobunzima obuphezulu, enobulukhuni be-Mohs obungu-9.2-9.8, okwesibili ngemuva kwedayimane elinzima kakhulu emhlabeni (izinga le-10), ngokuvamile yaziwa ngokuthi "isihlabathi sensimbi yegolide". Iphinde ibe nokusimama okuhle kwamakhemikhali nokuqina okuthile, futhi ingasetshenziswa ukwenza amasondo okugaya, ama-sandpaper, amabhande esihlabathi, amatshe amafutha, amabhlogo okugaya, amakhanda okugaya, ama-paste okugaya, kanye nokugaya nokupholisha i-silicon ye-monocrystalline, i-silicon ye-polycrystalline, namakristalu e-piezoelectric embonini ye-electronic emikhiqizweni yokubona.
(3) Izinto zokusetshenziswa ze-Metallurgical:
I-Silicon carbide ingasetshenziswa njenge-deoxidizer yokwenza insimbi kanye ne-modifier yesakhiwo se-cast iron. Ingasetshenziswa futhi njengempahla eluhlaza yokukhiqiza i-silicon tetrachloride futhi iyimpahla eyinhloko yomkhakha we-silicone resin. I-Silicon carbide deoxidizer iwuhlobo olusha lwe-deoxidizer eyinhlanganisela eqinile ethatha indawo yempushana ye-silicon yendabuko kanye ne-carbon powder ye-deoxidation. Uma kuqhathaniswa nenqubo yokuqala, inezindawo ezizinzile ngokomzimba namakhemikhali, umphumela omuhle we-deoxidation, isikhathi esifushane se-deoxidation, amandla alondoloziwe, ukwenza ngcono ukusebenza kahle kwensimbi, izinga lensimbi elithuthukisiwe, ukunciphisa ukusetshenziswa kwezinto ezingavuthiwe, ukunciphisa ukungcoliswa kwemvelo, izimo zokusebenza ezithuthukisiwe, kanye nezinzuzo ezithuthukisiwe zezomnotho ezibanzi zezithando zikagesi, konke okunenani elibalulekile.
3. I-silicon carbide optical reflector material
Izinto zobumba ezenziwe kusetshenziswa imisebenzi ekhethekile yezitsha zobumba ngokwezakhiwo ezibonakalayo ezinjengomsindo, ukukhanya, ugesi, uzibuthe, nokushisa zibizwa ngokuthi izitsha zobumba ezisebenzayo. Kunezinhlobo ezahlukene zezitsha zobumba ezisebenzayo ezinokusetshenziswa okuhlukile, futhi i-silicon carbide isetshenziswa kakhulu njengento yesibuko ekhanyayo emkhakheni wezitsha zobumba ezisebenzayo. I-ceramics ye-SiC inokuqina okukhethekile okuphezulu, ukuzinza okuhle kokushisayo namakhemikhali, i-coefficient ephansi yokuguqulwa kwe-thermal, kanye nokumelana nokukhanya kwezinhlayiya zesikhala. Ngezinqubo ezikhethekile zokukhiqiza, imizimba yezibuko engasindi ingatholakala.
4. Njengempahla ye-semiconductor
I-semiconductor yesizukulwane sesithathu iwumgogodla wezinto ezibonakalayo kanye nengxenye ye-elekthronikhi esekela ukusungulwa, ukuthuthukiswa, ukuguqulwa nokuthuthukiswa kwezikhali zokuvikela zikazwelonke, ukuxhumana kweselula kwe-5G, i-inthanethi yamandla, izimoto ezintsha zamandla, ezokuthutha ngololiwe kanye nezinye izimboni. Ngenxa yendima yayo ebalulekile ekuvikelekeni kuzwelonke, ekukhiqizeni ngobuhlakani, ekuthuthukisweni kwezimboni, ukongiwa kwamandla kanye nokuncishiswa kokungcola kanye nezinye izidingo ezinkulu zamasu, isiba iphoyinti lezobuchwepheshe lokuncintisana emhlabeni.
I-SiC, njengommeleli ojwayelekile wezinto zokwakha ze-semiconductor yesizukulwane sesithathu, okwamanje ingenye yezinto ezivuthwe kakhulu nezisetshenziswa kabanzi ze-bandgap semiconductor kubuchwepheshe bokukhiqiza ikristalu nokukhiqizwa kwedivayisi. Yakhe uchungechunge lomhlaba wonke lwempahla, idivayisi, kanye nezinhlelo zokusebenza. Kuyinto efanelekile ye-semiconductor yezinga lokushisa eliphezulu, imvamisa ephezulu, ukumelana nemisebe, kanye nezicelo zamandla aphezulu. Ngenxa yokwehliswa okukhulu kokusetshenziswa kwamandla kwemishini kagesi, izisetshenziswa zamandla e-silicon carbide zaziwa nangokuthi "imishini yamandla aluhlaza" eqhuba "inguquko yamandla entsha".
5. I-ejenti yokuqinisa kanye ne-toughening
Ngaphezu kwalezi zinhlelo zokusebenza ezingenhla, amadevu e-silicon carbide noma ama-silicon carbide fibers asetshenziswe kabanzi njengama-ejenti aqinisayo futhi aqinisayo ezintweni eziyinhlanganisela ngezinto ezisekelwe ensimbi noma ze-ceramic emikhakheni efana nemishini, ubunjiniyela bamakhemikhali, ukuvikela izwe, amandla, nokuvikelwa kwemvelo.
