Nibihe biranga imikorere nuburyo bukoreshwa bwa silicon carbide itanura?

Silicon carbide itanuraifite ibyiza byimbaraga nyinshi, ubukana bwinshi, kwihanganira kwambara neza, kurwanya ubushyuhe bwinshi, kurwanya ruswa, kurwanya ubushyuhe bukabije bwumuriro, gutwara ubushyuhe bwinshi, kurwanya okiside nziza nibindi.Ahanini ikoreshwa muguciriritse giciriritse, itanura ritandukanye ryokoresha ubushyuhe, metallurgie, inganda zimiti, ibyuma bidafite ferrous nibindi bikorwa.Silicon carbide itanuraikoreshwa cyane mu itanura rya metallurgical sintering hamwe na feri yo hagati yo gushyushya itanura, kandi uburebure bwayo burashobora gutegurwa ukurikije ibikenewe kurubuga.

Ibirangasilicon carbide itanura

Itanura rya silicon carbide itanura nigicuruzwa cyiza cya silicon karbide yacumuye mubushyuhe bwinshi hamwe na karubide ya silicon nkibikoresho byingenzi.Ifite ibyiza byo guhangana nubushyuhe bwo hejuru, kurwanya ruswa, kwihuta kwubushyuhe bwumuriro, imbaraga nyinshi, gukomera kwinshi, kwihanganira kwambara neza, guhangana nubushyuhe bwiza bwumuriro, imiyoboro minini yumuriro, kurwanya okiside nziza nibindi.Impera zombi zifite ibikoresho byihariye byo hejuru yubushyuhe bwo hejuru, kwangirika kwicyuma cyibikoresho byo gushyushya amashanyarazi (harimo inkoni ya karubide ya silicon, insinga y’amashanyarazi, nibindi) birashobora kwirindwa neza, kandi ibipimo nibyiza kuruta ubwoko bwibicuruzwa byose bya grafite. .Itanura rya silicon carbide itanura rifite ubushyuhe bwumuriro, irwanya okiside, irwanya ubushyuhe bwumuriro, ubushyuhe bukabije bwo kwambara, guhagarara neza kwimiti, kurwanya aside ikomeye, nta reaction kuri aside ikomeye na alkali.

Silicon carbide itanuratekinoloji yumusaruro: ibicuruzwa byarangiye bifata karubone ya silicon nkibikoresho byibanze byibanze, kandi nibicuruzwa byiza bya silicon karbide yarangiye ikozwe nubuhanga budasanzwe mubushyuhe bwinshi.Uburebure busanzwe bushobora gutegurwa ukurikije ibyo abakiriya bakeneye.Imikoreshereze yingenzi ya silicon carbide itanura: ikoreshwa cyane mumahugurwa yicyuma kitari ferrous, sisitemu yo kugabanya ibicuruzwa bya aluminium, imashini zo gucapa no gusiga amarangi, amahugurwa ya zinc na aluminiyumu no gutunganya ibicuruzwa byarangiye.

Iterambere ryinganda za silicon karbide

Carbide ya Silicon ifite ibiranga kwinjiza kwinshi, urusaku ruke, umurongo mwiza, nibindi, nibimwe mubikoresho byihuta byiterambere bya silicon karbide, kandi byambere bigera kubucuruzi.Ugereranije na MOSFETs, ntakibazo cyokwizerwa cyatewe nubusembwa bwa oxyde ya gate hamwe nubushobozi buke bwabatwara, kandi imikorere yayo ya unipolar ikomeza ubushobozi bwiza bwo gukora cyane.Mubyongeyeho, imiterere ya silicon karbide ihuza ifite umutekano muke kandi wizewe mubushyuhe bwo hejuru kuburyo voltage yumubare usanzwe ari mubi, ni ukuvuga, igikoresho gisanzwe gifungura, kikaba kidakwiriye cyane kubikoresho bya elegitoroniki, kandi ntibishobora guhuzwa nibisanzwe. umuzunguruko.Mugutangiza tekinoroji yigikoresho cyo gutera inshinge, igikoresho cyongerewe imbaraga muburyo busanzwe bwa reta cyateye imbere.Nyamara, ibikoresho byongerewe imbaraga akenshi bikozwe muburyo bwo kuranga ibintu bimwe na bimwe byiza birwanya kurwanya, bityo mubisanzwe gufungura (ubwoko bwa depletion) biroroshye kugera kumurongo mwinshi wimbaraga nubushobozi bugezweho, kandi ubwoko bwa depletion burashobora kugerwaho nukwikinisha bisanzwe mubikorwa bya leta.Uburyo bwa cascade bushyirwa mubikorwa binyuze murukurikirane rwa silicike nkeya ya silicon ishingiye kuri MOSFETs.Inzira ya kasike ya kasike isanzwe ihujwe nintego rusange ya silicon igikoresho cyo gutwara ibizunguruka.Imiterere ya caskade irakwiriye cyane kugirango isimbuze silikoni yumwimerere mugihe cyumubyigano mwinshi hamwe nimbaraga nyinshi, kandi irinda byimazeyo ikibazo cyo guhuza ibibazo byumuzunguruko.
