1, Siv rau cov ntaub ntawv gemstone
Hauv kev lag luam pob zeb diamond, silicon carbide kuj hu ua "moissanite". Cov ntaub ntawv pom ntau hauv kev ua lag luam yog cov khoom siv dag zog moissanite, thaum cov moissanite ntuj tsis tshua muaj, tsis tshua muaj uas nws tsuas yog tshwm sim hauv cov qhov meteorite 50000 xyoo dhau los.
2, Cov ntawv thov kev lag luam ib txwm muaj
Hauv kev lag luam ib txwm muaj, silicon carbide feem ntau yog siv ua cov khoom siv refractory, cov cuab yeej abrasive, thiab cov khoom siv metallurgical, uas yuav raug tshuaj xyuas cais hauv cov ntawv hauv qab no.
(1) Cov khoom tiv taus kub siab:
Siv cov yam ntxwv ntawm kev tiv taus corrosion, kev tiv taus kub siab, lub zog siab, kev ua tau zoo thermal conductivity, thiab kev tiv taus kev cuam tshuam ntawm cov ntaub ntawv silicon carbide, lawv tuaj yeem siv rau ntau yam smelting furnace linings, high-temperature furnace Cheebtsam, silicon carbide phaj, lining plates, supports, thiab ladles. Ntawm qhov tod tes, cov ntaub ntawv kub siab indirect cua sov tuaj yeem siv rau hauv kev lag luam smelting hlau tsis yog ferrous, xws li ntsug distillation furnace, arc phaj rau zinc hmoov furnace, thermocouple tiv thaiv raj, thiab lwm yam; Siv rau kev tsim cov khoom siv ceramic silicon carbide uas tiv taus hnav, tiv taus corrosion, thiab kub siab; Nws kuj tseem siv tau los ua rocket nozzles, roj turbine blades, thiab lwm yam. Tsis tas li ntawd, silicon carbide kuj yog ib qho ntawm cov ntaub ntawv zoo tshaj plaws rau lub hnub ci dej kub ntawm txoj kev loj, dav hlau runways, thiab lwm yam. Yog li ntawd, silicon carbide kuj muaj lub npe hu ua "refractory sand", uas, txawm hais tias feem ntau heev, qhia tag nrho nws cov khoom refractory.
(2) Cov khoom uas tiv taus kev hnav thiab kev xeb:
Vim tias silicon carbide muaj qhov nyuaj siab, nrog Mohs hardness ntawm 9.2-9.8, thib ob tsuas yog pob zeb diamond nyuaj tshaj plaws hauv ntiaj teb (qib 10), nws feem ntau hu ua "xuab zeb kub". Nws kuj muaj kev ruaj khov tshuaj zoo thiab qee qhov tawv, thiab tuaj yeem siv los ua cov log sib tsoo, ntawv xuab zeb, siv xuab zeb, pob zeb roj, cov thaiv sib tsoo, taub hau sib tsoo, sib tsoo pastes, thiab rau kev sib tsoo thiab polishing monocrystalline silicon, polycrystalline silicon, thiab piezoelectric crystals hauv kev lag luam hluav taws xob hauv cov khoom siv kho qhov muag.
(3) Cov khoom siv hlau ua los ntawm hlau:
Silicon carbide siv tau ua tus deoxidizer rau kev ua hlau thiab hloov kho rau cov qauv hlau cam khwb cia. Nws kuj siv tau ua cov khoom siv raw rau kev tsim silicon tetrachloride thiab yog cov khoom siv tseem ceeb rau kev lag luam silicone resin. Silicon carbide deoxidizer yog ib hom tshiab ntawm cov khoom sib xyaw ua ke deoxidizer uas hloov cov hmoov silicon ib txwm muaj thiab cov hmoov carbon rau deoxidation. Piv nrog rau cov txheej txheem qub, nws muaj cov khoom siv lub cev thiab tshuaj lom neeg ruaj khov dua, cov nyhuv deoxidation zoo, lub sijhawm deoxidation luv dua, txuag hluav taws xob, txhim kho kev ua haujlwm ntawm hlau, txhim kho qhov zoo ntawm hlau, txo cov khoom siv raw, txo cov pa phem ib puag ncig, txhim kho cov xwm txheej ua haujlwm, thiab txhim kho cov txiaj ntsig kev lag luam ntawm cov cub hluav taws xob, txhua yam muaj txiaj ntsig tseem ceeb.
3, Silicon carbide optical reflector khoom siv
Cov khoom siv ceramic uas tsim los ntawm kev siv cov haujlwm tshwj xeeb ntawm ceramics hauv cov yam ntxwv ntawm lub cev xws li suab, lub teeb, hluav taws xob, magnetism, thiab cua sov hu ua functional ceramics. Muaj ntau hom functional ceramics nrog kev siv sib txawv, thiab silicon carbide feem ntau yog siv los ua cov khoom siv iav hauv kev ua haujlwm ceramics. SiC ceramics muaj qhov tshwj xeeb siab, zoo thermal thiab tshuaj lom neeg ruaj khov, qis thermal deformation coefficient, thiab tiv taus qhov chaw me me irradiation. Los ntawm cov txheej txheem tsim khoom tshwj xeeb, lub cev iav sib dua tuaj yeem tau txais.
4, Ua ib yam khoom siv semiconductor
Lub semiconductor tiam thib peb yog cov khoom siv tseem ceeb thiab cov khoom siv hluav taws xob uas txhawb nqa kev tsim kho tshiab, kev txhim kho, kev hloov pauv thiab kev txhim kho ntawm cov riam phom tiv thaiv lub teb chaws, kev sib txuas lus 5G mobile, lub zog hauv Is Taws Nem, cov tsheb fais fab tshiab, kev thauj mus los ntawm tsheb ciav hlau thiab lwm yam lag luam. Vim nws lub luag haujlwm tseem ceeb hauv kev ruaj ntseg tiv thaiv lub teb chaws, kev tsim khoom ntse, kev txhim kho kev lag luam, kev txuag hluav taws xob thiab kev txo qis pa phem thiab lwm yam kev xav tau tseem ceeb, nws tab tom dhau los ua qhov chaw sib tw hauv ntiaj teb.
SiC, ua tus sawv cev ntawm cov ntaub ntawv semiconductor tiam peb, tam sim no yog ib qho ntawm cov ntaub ntawv semiconductor dav dav thiab siv dav hauv kev siv tshuab tsim khoom siv lead ua thiab kev tsim khoom siv. Nws tau tsim cov khoom siv thoob ntiaj teb, khoom siv, thiab kev siv lag luam. Nws yog cov khoom siv semiconductor zoo tagnrho rau kev siv kub siab, zaus siab, tiv taus hluav taws xob, thiab siv hluav taws xob siab. Vim tias kev siv hluav taws xob tsawg dua, cov khoom siv hluav taws xob silicon carbide kuj tseem hu ua "cov khoom siv hluav taws xob ntsuab" tsav "kev hloov pauv hluav taws xob tshiab".
5, Tus neeg sawv cev txhawb zog thiab tawv nqaij
Ntxiv rau cov ntawv thov saum toj no, silicon carbide whiskers lossis silicon carbide fibers tau siv dav dav ua cov neeg sawv cev zoo heev thiab cov neeg sawv cev tawv hauv cov ntaub ntawv sib xyaw nrog cov hlau lossis cov ntaub ntawv ceramic hauv cov teb xws li tshuab, tshuaj lom neeg engineering, kev tiv thaiv lub teb chaws, lub zog, thiab kev tiv thaiv ib puag ncig.
