Imiterere yubushakashatsi bwa silicon karbide ceramics

Yongeye gushyirwahosilicon karbide (RSiC) ceramicsni aibikoresho-byiza bya ceramic. Bitewe nubushyuhe buhebuje bwo kurwanya ubushyuhe, kurwanya okiside, kurwanya ruswa no gukomera cyane, bwakoreshejwe henshi mubice byinshi, nko gukora semiconductor, inganda zifotora amashanyarazi, itanura ryubushyuhe bwinshi nibikoresho bya shimi. Hamwe n’ibikenerwa n’ibikoresho bikora neza mu nganda zigezweho, ubushakashatsi n’iterambere ry’ubutaka bwa silicon karbide ceramics yongeye kwiyongera.

1. Tekinoroji yo gutegura yareystallised silicon carbide ceramics

Tekinoroji yo gutegura yo kongera gushyirwahosilicon carbide ceramicsahanini ikubiyemo uburyo bubiri: gushiramo ifu no gushira imyuka (CVD). Muri byo, uburyo bwo gucumura ifu nugushungura ifu ya silicon karbide munsi yubushyuhe bwo hejuru kuburyo ibice bya karibide ya silicon ikora imiterere yuzuye binyuze mu gukwirakwiza no kongera guhuza ibinyampeke. Uburyo bwo kubika imyuka ni ugushyira karubide ya silikoni hejuru yubutaka hifashishijwe imyuka ya chimique yubushyuhe bwinshi, bityo igakora firime ya karubide ya silicon nziza cyane cyangwa ibice byubatswe. Izi tekinoroji zombi zifite ibyiza byazo. Uburyo bwo gucumura ifu burakwiriye kubyara umusaruro munini kandi bufite igiciro gito, mugihe uburyo bwo kubika imyuka burashobora gutanga isuku nuburinganire bwimbitse, kandi bukoreshwa cyane mumashanyarazi.

2. Ibikoresho bifatika byareystallised silicon carbide ceramics

Ikintu cyihariye kiranga silicon carbide ceramics yongeye gukora ni imikorere yayo myiza mubushyuhe bwo hejuru. Ingingo yo gushonga yibi bikoresho ni hejuru ya 2700 ° C, kandi ifite imbaraga zumukanishi mubushyuhe bwinshi. Byongeye kandi, karbide ya silicon yongeye gushyirwaho kandi ifite imbaraga zo kurwanya okiside no kurwanya ruswa, kandi irashobora kuguma ihagaze neza mubidukikije bikabije. Kubwibyo, ububumbyi bwa RSiC bwakoreshejwe henshi mu murima w’itanura ry’ubushyuhe bwo hejuru, ibikoresho byo kugabanya ubushyuhe bwo hejuru, hamwe n’ibikoresho bya shimi.

Mubyongeyeho, karibide ya silicon yongeye gushyirwaho ifite ubushyuhe bwinshi kandi irashobora gutwara neza ubushyuhe, bigatuma igira akamaro gakomeye muriImashini ya MOCVDnibikoresho byo gutunganya ubushyuhe mubikorwa bya semiconductor wafer. Ubushyuhe bukabije bwumuriro hamwe nubushyuhe bwumuriro butuma imikorere yizewe yibikoresho mubihe bikabije.

3. Gukoresha imirima ya silicon carbide ceramics yongeye gushyirwaho

Gukora Semiconductor: Mu nganda za semiconductor, ceramics ya silicon karbide yongeye gukoreshwa ikoreshwa mugukora insimburangingo hamwe ninkunga mumashanyarazi ya MOCVD. Bitewe nubushyuhe bwo hejuru, kurwanya ruswa, hamwe nubushyuhe bukabije bwumuriro, ibikoresho bya RSiC birashobora gukomeza imikorere ihamye mubidukikije bigoye biterwa n’imiti, bigatuma ubwiza n’umusaruro wa waferi wa semiconductor.

Inganda za Photovoltaque: Mu nganda zifotora, RSiC ikoreshwa mugukora imiterere yingoboka yibikoresho bikura. Kubera ko imikurire ya kirisiti igomba gukorwa ku bushyuhe bwinshi mugihe cyo gukora ingirabuzimafatizo zifotora, kurwanya ubushyuhe bwa karubide ya silicon yongeye gushyirwaho bituma ibikoresho bikomeza kumara igihe kirekire.

Itanura ry'ubushyuhe bwo hejuru: Ubukorikori bwa RSiC nabwo bukoreshwa cyane mu ziko ry’ubushyuhe bwo hejuru, nk'imirongo n'ibigize itanura rya vacuum, itanura ryo gushonga n'ibindi bikoresho. Kurwanya ubushyuhe bwumuriro no kurwanya okiside bituma iba kimwe mubikoresho bidasimburwa munganda zubushyuhe bwo hejuru.

4. Icyerekezo cyubushakashatsi bwa silicon carbide ceramics yongeye gushyirwaho

Hamwe nogukenera ibikoresho bikoreshwa cyane, icyerekezo cyubushakashatsi bwa silicon carbide ceramics yongeye gushyirwaho buhoro buhoro. Ubushakashatsi bw'ejo hazaza buzibanda ku ngingo zikurikira:

Gutezimbere ubuziranenge bwibintu: Kugirango huzuzwe ibisabwa byisumbuyeho mumashanyarazi ya semiconductor hamwe na Photovoltaque, abashakashatsi barimo gushakisha uburyo bwo kunoza isuku ya RSiC batezimbere ikoranabuhanga ryangiza imyuka cyangwa binjiza ibikoresho bishya bibisi, bityo bikazamura agaciro kayo gukoreshwa murimurima yubuhanga buhanitse. .

Kunoza microstructure: Mugucunga uburyo bwo gucumura no gukwirakwiza ifu yifu, microstructure ya carbide ya silicon yongeye gushyirwaho irashobora kurushaho kunozwa, bityo igateza imbere imiterere yubukanishi no kurwanya ubushyuhe bwumuriro.

Ibikoresho bikora: Kugirango uhuze nibidukikije bigoye gukoresha, abashakashatsi baragerageza guhuza RSiC nibindi bikoresho kugirango bateze imbere ibikoresho bifatika hamwe nibintu byinshi, nkibikoresho bya silicon karbide bishingiye ku bikoresho bifatika hamwe no guhangana n’amashanyarazi menshi.

5. Umwanzuro

Nkibikoresho bikora cyane, ceramics ya silicon carbide yongeye gukoreshwa mumirima myinshi kubera imiterere myiza yubushyuhe bwinshi, kurwanya okiside no kurwanya ruswa. Ubushakashatsi bw'ejo hazaza buzibanda ku kuzamura ubuziranenge bwibintu, kunoza microstructure no guteza imbere ibikoresho bikora kugirango bikemure inganda zikenewe. Binyuze muri ubwo buhanga mu ikoranabuhanga, ceramics ya silicon yongeye gushyirwaho biteganijwe ko izagira uruhare runini mu buhanga buhanitse.
