Silicon Carbide (SiC) yog qhov sib xyaw ua ke ntawm cov ntsiab lus carbon thiab silicon. Nws yog ib qho nyuaj heev, siab thermal conductivity, tsis tshua muaj coefficient ntawm expansion, thiab chemically ruaj khov khoom uas yog dav siv nyob rau hauv ntau yam kev lag luam teb. Silicon carbide, tseem hu ua adamantine los yog moissanite, muaj nyob rau hauv qhov tsis tshua muaj cov ntxhia, tab sis feem ntau silicon carbide siv hauv kev lag luam yog tsim khoom hluavtaws.
Cov yam ntxwv ntawm Silicon carbide
1. High hardness: Silicon carbide yog thib ob tsuas yog pob zeb diamond hauv hardness, nrog Mohs hardness ze rau 9.5, yog li nws feem ntau siv rau hauv cov cuab yeej txiav thiab cov khoom siv abrasive.
2. High Thermal Conductivity: Silicon Carbide muaj cov thermal conductivity zoo, uas ua rau nws ua kom cov cua sov dissipate zoo txawm tias nyob rau hauv qhov kub thiab txias.
3. High Temperature Resistance: Silicon carbide muaj qhov melting point ntawm kwv yees li 2700 degree, thiab muaj peev xwm nyob ruaj khov ntawm qhov kub thiab txias, ua rau nws haum rau siv nyob rau hauv high-temperature ib puag ncig.
4. Corrosion kuj: Silicon carbide tsis tshua muaj resistant rau acids, alkalis thiab oxidizers, ua rau nws haum rau siv nyob rau hauv hnyav tshuaj.
5. Cov Khoom Siv Hluav Taws Xob: Silicon carbide yog cov khoom siv hluav taws xob broadband nrog cov khoom siv hluav taws xob zoo, ua rau nws tsim nyog rau cov khoom siv hluav taws xob siab thiab cov khoom siv hluav taws xob ntau.
Kev siv silicon carbide
1. Abrasives thiab txiav cov cuab yeej: Vim nws cov hardness siab, Silicon Carbide yog siv dav hauv kev tsim cov abrasives, txiav cov cuab yeej, sib tsoo lub log thiab cov ntawv xuab zeb, uas tsim nyog rau kev ua cov ntaub ntawv nyuaj xws li iav, ceramics thiab pob zeb.
2. Cov ntaub ntawv refractory: Vim nws qhov kub thiab txias tsis kam thiab oxidation tsis kam, silicon carbide yog siv los ua kub kub hauv ob sab phlu, kiln rooj tog thiab lwm yam ntaub ntawv refractory hauv steel, non-ferrous hlau, ceramic thiab lwm yam lag luam.
3. Cov khoom siv semiconductor: Silicon carbide yog ib qho ntawm cov khoom siv semiconductor dav dav, siv dav hauv kev tsim cov khoom siv hluav taws xob, cov khoom siv hluav taws xob siab, xws li diodes, MOSFETs, IGBTs, thiab lwm yam, tshwj xeeb tshaj yog tsim rau cov tsheb fais fab, Hnub ci inverters thiab cov khoom siv hluav taws xob siab.
4. Cov Ceramics Ceramics: Silicon carbide ceramics muaj lub zog siab thiab hnav tsis kam, thiab feem ntau yog siv rau hauv kev tsim cov khoom hnav-tiv taus, sealing rings, bearings, thiab lwm yam xav tau cov khoom siv tshuab.
5. Thaum tshav kub kub exchanger: Vim nws zoo heev thermal conductivity thiab corrosion kuj, silicon carbide yog siv raws li ib tug zoo heev tshav kub exchanger khoom nyob rau hauv tshuaj, zog thiab ib puag ncig engineering.
Qhov zoo ntawm silicon carbide
- Kev txuag hluav taws xob thiab kev ua haujlwm siab: Silicon carbide cov cuab yeej muaj peev xwm ua kom lub zog hloov pauv ntawm hluav taws xob thiab txo qis zog, uas ua rau lawv muaj txiaj ntsig zoo hauv kev siv hluav taws xob hluav taws xob.
- Kev ruaj ntseg: Txawm tias nyob rau hauv ib puag ncig huab cua, silicon carbide tswj cov khoom zoo heev thiab tshuaj lom neeg, ua rau nws tsim nyog rau kev siv hauv cov xwm txheej hnyav.
- Lub neej ntev: Vim nws cov khoom hnav thiab kev tiv thaiv corrosion, cov khoom siv silicon carbide feem ntau muaj lub neej ua haujlwm ntev, txo tus nqi hloov thiab kho.
Nrog nws cov khoom tshwj xeeb ntawm lub cev thiab tshuaj lom neeg, silicon carbide tau dhau los ua cov khoom siv tsis raug thiab tseem ceeb hauv kev lag luam niaj hnub, tshwj xeeb tshaj yog nyob rau hauv high-tech teb nrog dav daim ntawv thov kev cia siab.
