1, Siv rau gemstone cov ntaub ntawv
Hauv kev lag luam gemstone, silicon carbide tseem hu ua "moissanite". Cov ntaub ntawv uas pom nyob rau hauv kev ua lag luam feem ntau yog cov khoom tsim los ntawm moissanite, thaum lub ntuj moissanite tsis tshua muaj heev, yog li tsis tshua muaj tshwm sim nyob rau hauv meteorite craters 50000 xyoo dhau los.
2 、 Cov kev siv niaj hnub siv
Hauv kev lag luam ib txwm muaj, silicon carbide feem ntau yog siv los ua cov khoom siv refractory, cov cuab yeej abrasive, thiab cov khoom siv hlau, uas yuav raug tshuaj xyuas nyias hauv cov ntawv hauv qab no.
(1) Cov khoom siv kub kub ua haujlwm:
Siv cov yam ntxwv ntawm kev tiv thaiv corrosion, kub tsis kam, siab zog, zoo thermal conductivity, thiab cuam tshuam tsis kam ntawm silicon carbide cov ntaub ntawv, lawv tuaj yeem siv rau ntau yam smelting furnace linings, high-temperature furnace Cheebtsam, silicon carbide daim hlau, hauv ob sab phlu daim hlau, kev txhawb nqa, thiab ladles. Ntawm qhov tod tes, cov khoom siv hluav taws xob kub tsis ncaj tuaj yeem siv rau hauv kev lag luam uas tsis yog-ferrous hlau smelting, xws li ntsug distillation furnaces, arc daim hlau rau zinc hmoov furnaces, thermocouple tiv thaiv raj, thiab lwm yam; Siv los tsim cov khoom siv silicon carbide ceramics uas hnav-tiv taus, corrosion-resistant, thiab kub-resistant; Nws kuj tseem siv tau los ua cov foob pob hluav taws xob, roj turbine hniav, thiab lwm yam. Tsis tas li ntawd, silicon carbide kuj yog ib qho ntawm cov khoom siv zoo tshaj plaws rau lub hnub ci dej rhaub ntawm txoj kev loj, dav hlau khiav, thiab lwm yam. Yog li ntawd, silicon carbide kuj muaj lub npe hu ua "cov xuab zeb refractory", uas, txawm hais tias muaj ntau heev, tag nrho nws cov khoom refractory.
(2) Hnav resistant thiab corrosion resistant khoom:
Feem ntau vim hais tias silicon carbide muaj ib tug siab hardness, nrog ib tug Mohs hardness ntawm 9.2-9.8, thib ob tsuas yog rau lub ntiaj teb no lub hardest pob zeb diamond (theem 10), nws yog feem ntau hu ua "kub steel xuab zeb". Nws kuj muaj cov tshuaj lom neeg ruaj khov zoo thiab qee qhov tawv tawv, thiab tuaj yeem siv los ua kev sib tsoo log, ntawv xuab zeb, siv xuab zeb, roj pob zeb, sib tsoo blocks, sib tsoo taub hau, 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) Metallurgical raw khoom:
Silicon carbide tuaj yeem siv los ua deoxidizer rau steelmaking thiab hloov kho rau cov qauv hlau cam. Nws tseem tuaj yeem siv los 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 yam tshiab ntawm cov muaj zog composite deoxidizer uas hloov cov tsoos silicon hmoov thiab carbon hmoov rau deoxidation. Piv nrog rau cov txheej txheem qub, nws muaj lub cev ruaj khov thiab tshuaj lom neeg zoo, cov nyhuv deoxidation zoo, lub sijhawm luv deoxidation, txuag lub zog, txhim kho steelmaking efficiency, txhim kho steel zoo, txo cov khoom siv raw, txo cov kuab paug ib puag ncig, txhim kho kev ua haujlwm, thiab txhim kho cov txiaj ntsig kev lag luam ntawm cov hluav taws xob hluav taws xob, tag nrho cov khoom muaj txiaj ntsig tseem ceeb.
3, Silicon carbide optical reflector khoom
Cov khoom siv ceramic tsim los siv cov haujlwm tshwj xeeb ntawm ceramics hais txog lub cev muaj zog xws li suab, lub teeb, hluav taws xob, hlau nplaum, thiab cua sov hu ua haujlwm ceramics. Muaj ntau hom kev ua haujlwm ceramics nrog kev siv sib txawv, thiab silicon carbide feem ntau yog siv los ua cov khoom siv iav hauv kev ua haujlwm ntawm ceramics. SiC ceramics muaj qhov tshwj xeeb nruj, zoo thermal thiab tshuaj ruaj khov, tsis tshua muaj thermal deformation coefficient, thiab tsis kam mus rau qhov chaw particle irradiation. Los ntawm cov txheej txheem tsim tshwj xeeb, lub cev iav lub cev tuaj yeem tau txais.
4, Raws li cov khoom siv semiconductor
Lub tiam thib peb semiconductor yog cov khoom siv tseem ceeb thiab cov khoom siv hluav taws xob txhawb nqa kev tsim kho tshiab, kev tsim kho, kev hloov pauv thiab kho dua tshiab ntawm cov cuab yeej tiv thaiv hauv tebchaws, 5G mobile kev sib txuas lus, lub zog Internet, lub zog tshiab tsheb, tsheb ciav hlau thiab lwm yam lag luam. Vim tias nws lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev ruaj ntseg hauv tebchaws, kev tsim khoom ntse, kev txhim kho kev lag luam, kev txuag hluav taws xob thiab kev txo qis emission thiab lwm yam kev xav tau tseem ceeb, nws tau dhau los ua lub ntsiab lus ntawm kev sib tw hauv ntiaj teb.
SiC, raws li tus neeg sawv cev ntawm cov khoom siv semiconductor thib peb, tam sim no yog ib qho ntawm cov paub tab thiab siv dav bandgap semiconductor cov ntaub ntawv hauv cov khoom siv siv lead ua thiab cov cuab yeej tsim khoom. Nws tau tsim cov khoom siv thoob ntiaj teb, cov cuab yeej siv, thiab daim ntawv thov kev lag luam saw. Nws yog cov khoom siv semiconductor zoo tshaj plaws rau kev kub kub, siab zaus, hluav taws xob tiv thaiv, thiab kev siv hluav taws xob siab. Vim qhov txo qis hauv kev siv hluav taws xob ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob silicon carbide kuj tseem hu ua "cov khoom siv ntsuab ntsuab" uas ua rau "hloov lub zog tshiab".
5 、 Kev txhawb zog thiab toughening tus neeg sawv cev
Ntxiv rau cov ntawv thov saum toj no, silicon carbide whiskers los yog silicon carbide fibers tau dav siv los ua cov khoom siv dag zog zoo thiab ua kom tawv nqaij hauv cov ntaub ntawv sib xyaw nrog cov hlau los yog cov khoom siv ceramic hauv kev lag luam xws li tshuab, tshuaj engineering, kev tiv thaiv hauv tebchaws, lub zog, thiab kev tiv thaiv ib puag ncig.
