Uburyo bwo kubyaza umusaruro inganda za silicon karbide ya reaction igomba kuba yujuje ubuziranenge

Uburyo bwo gukora inganda zo mu bwoko bwa silicon karbide ni ugukuramo umucanga wa quartz wo mu rwego rwo hejuru hamwe na kokiya ya peteroli ibarwa mu itanura rishyushya amashanyarazi. Ibice bya karubide itunganijwe neza bikozwe mubicuruzwa bifite ubunini butandukanye bwo kugabura, kumenagura, aside ikomeye no gukaraba alkali, ibikoresho byo gutandukanya magneti no gusuzuma cyangwa gutandukanya amazi.

Carbide ya silicon ifite ubwoko bubiri bwibanze bwa karikide yumukara wa silicon na karbide yicyatsi kibisi, byose ni ibya α-SiC. Car Carbide ya silicon yumukara irimo SiC hafi 95%, kandi ihindagurika ryayo iruta karbide yicyatsi kibisi, inyinshi murizo zikoreshwa mukubyara no gutunganya ibikoresho bibisi bifite imbaraga nkeya, nkibirahuri byanduye, farufari, amabuye, inganda, ibyuma byingurube na ibyuma by'agaciro. Carb Carbide yicyatsi kibisi irimo SiC hafi 97% hejuru, kwikarisha ni byiza, inyinshi murizo zikoreshwa mugukora no gutunganya ibikoresho bya karbide, ibyuma bya titanium na optique, kandi bikoreshwa no kubaha umurongo wa silinderi no gutonesha umuvuduko mwinshi ibikoresho by'ibyuma. Hiyongereyeho, hari metero kibe ya karubide ya silicon, ni kirisiti yicyatsi kibisi yoroheje yakozwe nuburyo bushya, kandi ikoreshwa mugutanga ifumbire ikwiranye no kwihanganira super-finingi, ishobora gutuma ubukana bwubuso buva kuri Ra32 ~ 0.16μm butunganywa kuri Ra0.04 ~ 0.02μm.

Uburyo bukoreshwa bwa reaction sintering silicon karbide

(2) Nkumuti wangiza kandi wibikoresho byangiza ruswa yinganda. Carbide ya Silicon ikubiyemo ahanini ibintu bine byingenzi bikoreshwa, aribyo: ubukorikori bukora, ibikoresho byo mu rwego rwo hejuru byo kwangirika, ibikoresho birwanya kwambara no gushonga ibikoresho bibisi. Kuri iki cyiciro, silicon karbide roughage irashobora gutangwa muburyo bwinshi, ntabwo aribicuruzwa byubuhanga buhanitse, kandi gukoresha ifu ya karubide ya nano-silicon karbide irimo ibintu byinshi bya siyansi nubuhanga ntibishobora gutanga ingaruka nini mugihe gito.

Igipimo cyo gukoreshwa: Kuri metero 3-12 zifotora ya selile, selile Photovoltaic, potassium arsenide, resonator ya quartz nibindi bice. Inganda zikomoka ku mirasire y'izuba, inganda ziciriritse, inganda za piezoelectric kristal inganda zinganda umushinga wo gutunganya ibikoresho bibisi.

Imyitozo ngororamubiri ya silicon karbide - impamvu zo gushiraho

Umuvuduko ukabije w’ubushyuhe hamwe nubushyuhe bwo hejuru bukozwe mu nsi yisi yatewe mu butaka hamwe na lava. Nka Tayilande, Ositaraliya, Shandong y'Ubushinwa, Amerika n'ibindi bihugu. Icyuma cya jade ikorwa no gukoraho metamorphism. Nka Miyanimari, Kashmir, Anhui y'Ubushinwa n'utundi turere. Rubisi kwisi ikomoka ahanini kubashyira. Binyuze mu bwoko butandukanye bwa emaragido y’ibidukikije, amabuye y'agaciro yubururu hamwe nisuri yegeranya yisuri ya sinbone ya silicon karbide hamwe nubutare bwa silikoni karemano, karubone, ibiti byimbaho, umunyu winganda nkibikoresho byibanze byibanze, mubushuhe bwo gushyushya itanura ryamashanyarazi. Kwiyongera kw'ibiti by'ibiti ni ugukora agace gato k'ibintu bivanze ku bushyuhe bwo hejuru kugira ngo bitange imiterere yuzuye, ifasha mu kwerekana umubiri munini w’imyuka n’umuvuduko ukuramo, kugirango wirinde impanuka ziturika, bitewe n’ibisekuru ya toni 1 ya karubide ya silicon, irashobora gutanga hafi 1.4t ya monoxyde de carbone (CO). Uruhare rwumunyu winganda (NaCl) rufasha gukuraho okiside ya aluminium, ibivanze nibindi bisigara mubikoresho.
