Silicon carbide ceramic ni ceramic ceramic hamwe na karubide ya silicon (SiC) nkibice byingenzi, bifite imbaraga nyinshi, birwanya ubushyuhe bwinshi kandi birwanya ruswa, kandi bikoreshwa cyane mubikorwa byinganda.
Igikorwa cyo kubyaza umusaruro gikubiyemo cyane cyane gucumura gushushe, gucumura bidafite ingufu, gucumura reaction nubundi buryo, binyuze mukugenzura ubushyuhe bwa sinte (dogere 1450-2450) no kongeramo inyongeramusaruro (nka karbone ya boron, alumina) kugirango ugere kuri densification
Ibicuruzwa bisobanura
Igisubizo cyacumuye silicon karbide ceramic ibicuruzwa bifite ibintu byingenzi bikurikira:
Ibikoresho byiza bya tekinike: Gukomera cyane (Mohs igipimo cya 9.0-9.5 hafi ya diyama), hamwe n'imbaraga za megapascal 400-600, kandi zigakomeza imbaraga nyinshi nubwo haba hari ubushyuhe bwa dogere 1600.
Imiterere idasanzwe yubushyuhe: Ubushyuhe bukabije bwumuriro (120 - 220 W / m · K), coefficente yo kwagura ubushyuhe buke (hafi 4.0 × 10 ^ {- 6} / K), ishobora guhangana nubushyuhe bwo hejuru bugera kuri dogere 1400 - 1600, hamwe no guhangana nubushyuhe bukabije (itandukaniro ryubushyuhe burenga dogere 800).
Imiti idasanzwe ya chimique: Irwanya aside na alkali ruswa, ifite imbaraga zo kurwanya okiside ikomeye mubutaka butari - oxyde ceramique, ibereye kwangirika kandi hejuru - ibidukikije.
Kuramba no guhindagurika: Kuramba birenze inshuro 10 zubukorikori busanzwe, kandi kandi bufite imitungo ya semiconductor (bitandukanye nubutaka busanzwe bukora insimburangingo), bigatuma bukwiranye nakazi gakabije.
Ceramics ya karibide ya silicon, kubera ubukana bwayo bwinshi, kurwanya ubushyuhe bwinshi, kurwanya ruswa, ubukana bwumuriro mwinshi hamwe no kurwanya kwambara neza, bigira uruhare runini mubikorwa bitandukanye byinganda. Ibyingenzi byingenzi nibi bikurikira:
I. Ubushyuhe bwo hejuru ninganda za Metallurgiki
Hejuru - itanura ryubushyuhe: Gukora itanura ry itanura, umusaraba, nozzles, gutwika itanura, nibindi, bishobora gukora neza mubushyuhe buri hejuru ya dogere 1600.
Ibikoresho bivunika: Byakoreshejwe mugutwika itanura, amatafari yangiritse, hamwe nimbaho zokwirinda, kurwanya isuri ukoresheje ibyuma bishongeshejwe kandi byongerera igihe ubuzima ibikoresho.
Gushonga ibyuma: Nka deoxidizers kugirango yongere amazi meza yicyuma, cyangwa akozwe muburyo bwo guhora batera impeta, imiyoboro irinda thermocouple, guhuza neza gushonga.
2. Gukora imashini no kwambara umurima wo kurwanya
Ibice bifunga kashe: Impeta zifunga imashini zikoreshwa muri pompe yimiti na pompe zamazi, hamwe no kurwanya ruswa inshuro icumi ibyuma bisanzwe, bitezimbere mubuzima bwa serivisi.
Ibikoresho byo gutema no gukata: Hejuru - kwihuta, kuyobora gari ya moshi, hamwe nibikoresho byo gutema, bikwiranye n'ubushyuhe bwo hejuru - n'ubushyuhe bwo hejuru -, bikagabanya kwambara ibikoresho.
Kwambara imiyoboro - irwanya: Imiyoboro yo gutwara amabuye y'agaciro, imirongo yimodoka, hamwe no kwihanganira kwambara inshuro 5-20 z'icyuma.
3. Semiconductor ninganda za elegitoroniki
Ibikoresho bya Semiconductor: Gusya disiki, ibikoresho byo gutunganya wafer, birwanya ubushyuhe bwinshi no kwangirika kwimiti, kwemeza neza gutunganya neza.
Ubushuhe bwo gukwirakwiza ubushyuhe: Ubushyuhe bwo gukwirakwiza ibikoresho bikoresha ingufu za - (nka IGBT, LED), hamwe n’ubushyuhe bwa 270 W / m · K, bikazamura ubushyuhe bwo gukwirakwiza ubushyuhe.
Ibikoresho bya elegitoronike: Abafata inkuba, voltage - birwanya ibyiyumvo, nibindi, ibikoresho byamashanyarazi bikoresha imiterere yabyo idafite umurongo.
4. Umwanya wo kurengera imiti n’ibidukikije
Ruswa - ibikoresho birwanya: Valve, imirongo ya reaktor, imiyoboro, irashobora kwihanganira acide ikomeye hamwe nishingiro rikomeye (nka 98% acide sulfurike yibanze).
Ibidukikije bikoreshwa: Hejuru - ubushyuhe bwumwotsi ushungura (nko gutwika imyanda), catalitiki yubuki butwara ceramic itwara imodoka.
Ibice byingufu: Ihuza ingirabuzimafatizo, imirasire yizuba yumuriro, hamwe nubushyuhe burenga dogere 1000.
5. Imirima idasanzwe kandi igaragara
Inganda za kirimbuzi: Ibitoro bya kirimbuzi bifata imiyoboro, ibikoresho by'imyanda, irwanya imishwarara ya neutron n'ubushyuhe bwinshi.
Ibikoresho bitagira amasasu: Gukomatanya amasasu yamashanyarazi binyuze mubuvuzi bukaze, hamwe nuburemere bwinshi nubucucike buke (3.10-3.15 g / cm³).
Inganda za Photovoltaque: Ibigize gutwara transport ya polysilicon etching, gukemura impuzu nyinshi nibibazo bikomeye byo kwangirika.
Ububiko bwa silicon karbide butera udushya mu ikoranabuhanga mu mbaraga nshya (selile lisansi ya hydrogène, Photovoltaque), semiconductor, hamwe n’ibikoresho byanyuma -, kandi ni ibikoresho byatoranijwe mubihe bikabije nkubushyuhe bwinshi, ruswa, no kwambara cyane.

Kuki duhitamo
Igisubizo cyihuse Ibicuruzwa bifite imikorere ihanitse Ibicuruzwa bifite imikorere ihanitse
kuki uhitamo ibicuruzwa byacu
Uburambe 1. 20 imyaka y'uburambe mu guta icyuma, icyizere cyiza, gutanga ku gihe
2. Ibikoresho byo gutunganya no kugenzura neza birashobora gutanga ibice byuzuye kandi byujuje ibisabwa byo kugenzura abakiriya
3. Ifite uburenganzira bwigenga bwo gutumiza no kohereza hanze kandi irashobora kohereza ibicuruzwa mubice byose byisi
Ibirangantego: reaction yacumuye silicon karbide ceramic, Ubushinwa reaction yahinduye silicon carbide ceramic ceramic, abatanga ibicuruzwa, uruganda
