Koj puas tau muaj riam ua mov no: koj cov riam ua mov tau npub tom qab siv kho vajtse ua kom zoo dua qub, thiab thaum kws kho tshuab siv cov log sib tsoo sai sai los txhuam nws rov qab; Los yog hauv cov tuam txhab, cov me me uas siv rau kev tua cov khoom siv hluav taws xob thiab cov hlau smors, txawm tias lawv muaj kev kub ntxhov siab tshaj 1000℃tau muaj lawv cov phab ntsa sab hauv. Qhov tseeb, qab ob qho ntawm cov khoom lus dag no tib yam "kev lag luam txhua- rounder" -Silicon Carbide Dub.
01 Cia peb nkag siab: Dab tsi yog cov xim dub dub?
Raws li nws lub npe qhia, Dub silicon carbide lub ntsiab lus tseem ceeb yog "carbon" thiab "sillicon," nrog cov tshuaj lom neeg sic. Qhov tseem ceeb, nws yog synthetically tsim inorganic tsis- nws yog xim hlau. Nws tsis yog cov ntxhia, tab sis cia li "ua kom zoo" los ntawm cov tshuaj txhua hnub, thiab tom qab ntawd nws raug rho tawm haujlwm me me thaum 1800 {} 2200℃rau ob peb hnub. Ntawm qhov kub siab no, cov silicon hauv cov roj av quartz thiab cov pa roj hmab rau hauv cov roj av ua kom hnov qab, qhov no ua rau cov nqaij tawv dub-qhov no yog cov cua silicon carmide.
Vim li cas nws dub? Vim tias nws txoj kev coj dawb huv tshwj xeeb tshaj yog nyob ntawm 95% thiab 98%), thiab tus nqi me me uas cuam tshuam rau nws lub ntsej muag txho tsaus lossis xim dub. Yog hais tias lub purity tau nce mus rau ntau tshaj 99%, nws ua lwm cov khoom lag luam {}} nplooj ntsuab silicon carbide (nrog tus hue ntsuab ntsuab).
02. Lub "superpowers" ntawm dub silicon carbide: vim li cas nws thiaj li ua ib qho kev lag luam darling?
Silicon Carbide ci hauv ntau lub teb ua tsaug rau nws peb qhov kev cuam tshuam, txhua qhov chaw nyob ib qho mob tseem ceeb hauv kev lag luam:
1. Kev nyuaj siab, ua rau nws zoo kawg ntawm kev sib tsoo.
Ntawm tsis - nws cov ntaub ntawv metallic nyob rau hauv xwm, alumina) {1} nws mohs haloness mus txog 9.2 (Pob zeb diamond yog 10). Qhov kev nyuaj no ua rau nws "cov kev sib tsoo zoo nkauj": ntau txoj kev sib tsoo uas siv hauv tsev kom muaj riam phom thiab txiab yog ua los ntawm cov cua dub silicon carbide do nrog Resin; Sandpaper thiab sib tsoo Disc
2. Kev kub siab tsis kam thiab corrosion tsis kam, ua yeeb yam raws li "Hluav Taws Xob Cov Neeg Saib Xyuas"
Silicon Carbide Dub muaj qhov taw tes melting kom siab li 2700 degree, thiab nws yuav tsis deform lossis yaj txawm tias tom qab ntev ntawm 1600 degree. Ntxiv mus, nws tsis ntshai ntawm cov kua qaub lossis alkalis, thiab txawm tias muaj zog acids thiab alkalis muaj teeb meem corroding nws. Cov khoom no ua rau nws "tiv thaiv lub cev" rau cov khoom siv thiab cov nroj tsuag hauv cov hmoov av uas muaj los ntawm cov plaub hau sib dhos ua los ntawm cov plaub hau dub, uas tuaj yeem tiv taus ntau kub thiab txo cov cua sov; Qee qhov siab - kub muaj cov kav dej kub thiab cov roj kub yog cov khoom siv txhawm rau txhawm rau txhawm rau tiv thaiv corrosion los ntawm high} pa roj lossis kua.
3. Nws tuaj yeem ua hluav taws xob thiab cua sov, thiab tseem tuaj yeem ua raws li "txhawb nqa" hauv electronics.
Tsis zoo li ntau tsis - cov ntaub qhwv ntsej muag (xws li muab cov roj hluav taws xob rau hluav taws xob ( overheating; Hauv qee qhov siab - Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob (xws li cov tshuab hloov hluav taws xob thiab cov tshuab ua kom sov) ua los ntawm cov khoom siv dub kuj tau siv los ua haujlwm ruaj khov ntawm cov khoom siv.
03 Dhau li ntawm kev sib tsoo thiab nrog kev kub siab, dab tsi ntxiv ntxiv rau cov carmide blicon ua?
Cov kev siv ntawm cov dub silicon carbide yog qhov dav dav dua li koj yuav xav txog tej yam; Nws tuaj yeem nrhiav tau hauv txhua yam ntawm kev lag luam ib txwm muaj los tawm teb.
Hauv kev tsim kho kev tsim kho, sib xyaw dub cov nplais rau hauv cov pob zeb tuaj yeem txhim kho cov kev coj tsis kam ntawm txoj kev thiab ntau dua 30% thiab tseem ua rau lawv khov {1} {resistant. Hom "Silicon carlicon qhob no" yog siv rau ntau qhov chaw txias ntawm cov cheeb tsam txias ntawm sab qaum teb.
Nyob rau hauv ib puag ncig teb, "Honeycomb cov neeg nqa khoom muaj zog"
Hauv cov photovoltaic, cov hmoov dub zoo nkauj heev yog xav tau ua "abrasive" thaum ua cov sila photrics los ua cov wafers nyias thiab tiaj, ua kom muaj zog ntau tiam.
04 Tau dub caricon carbide ua tau ntau dua "muaj zog" yav tom ntej?
Nrog kev txhim kho thev naus laus zis ua rau muaj kev tshawb fawb txog kev ua kom zoo li qub, thiab siv hluav taws xob ntau dua noj nyob rau yav tom ntej; Lwm tus tab tom sim ua kom dub rau hauv "cov khoom siv hluav taws xob zoo nkauj" los pab khaws cov hluav taws xob hluav taws xob los ntawm cov teeb meem hluav taws xob thiab cua lub zog ntawm "kev nyuaj siab tshiab.
