Cov ntsiab lus ntawm Silicon carbide

 

Ua ntej, cov khoom yam ntxwv ntawm emery
Emery, nws lub npe tshuaj yog silicon carbide (SiC), yog ib qho kev sib xyaw ua ke ntawm ob lub ntsiab lus: silicon (Si) thiab carbon (C). Nyob rau hauv qhov xwm txheej, ntuj silicon carbide cov zaub mov muaj tsawg heev, yog li feem ntau ntawm silicon carbide siv nyob rau hauv kev lag luam yog tau los ntawm dag synthesis. Emery muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg xws li siab hardness, siab melting point, hnav tsis kam thiab corrosion kuj, uas ua rau emery dav siv nyob rau hauv ntau lub teb.
Thib ob, cov txheej txheem synthesis ntawm emery
Lub synthesis ntawm emery yog tsuas yog ua tiav los ntawm reacting silica thiab coke ntawm qhov kub thiab txias. Hauv cov txheej txheem no, silicon hauv silica thiab carbon hauv coke ua ke los ua silicon carbide crystals. Qhov kub ntawm cov hluavtaws emery feem ntau yog siab li ntau txhiab degrees Celsius, yog li nws yog ib qho tsim nyog los tswj cov kev mob tshwm sim thiab xyuas kom meej cov khoom zoo nrog kev pab los ntawm cov khoom siv thiab kev siv tshuab. Lub synthesized emery tuaj yeem raug crushed thiab tshuaj ntsuam kom tau cov khoom sib txawv granularity thiab purity kom tau raws li qhov xav tau ntawm kev lag luam sib txawv.
Thib peb, daim ntawv thov teb ntawm emery
1. Abrasive kev lag luam: emery yog dav siv los ua abrasive thiab abrasive khoom vim nws siab hardness thiab hnav tsis kam. Nws tuaj yeem siv los tsim cov cuab yeej sib tsoo xws li kev sib tsoo lub log, cov ntawv xuab zeb thiab cov hlua khi, thiab siv cov khoom siv polishing xws li hlau thiab ceramics.
2. Refractory kev lag luam: emery muaj cov yam ntxwv ntawm siab melting point thiab corrosion kuj, yog li nws kuj yog siv los ua raw khoom rau manufacturing refractories. Nws tuaj yeem tiv taus qhov ntsuas kub thiab huab cua ib puag ncig thiab ua lub luag haujlwm tseem ceeb hauv metallurgy, ceramics, iav thiab lwm yam lag luam.
3. Kev lag luam semiconductor: Nyob rau hauv xyoo tas los no, nrog kev txhim kho txuas ntxiv ntawm semiconductor technology, emery tau siv dav hauv kev lag luam semiconductor. Nws tuaj yeem siv los ua cov khoom siv substrate los tsim cov khoom siv silicon-based semiconductor thiab txhim kho kev ua haujlwm thiab kev ruaj ntseg ntawm cov khoom siv.
Piv txwv li, emery, raws li cov khoom siv ua haujlwm siab, tau qhia nws qhov zoo thiab qhov tseem ceeb hauv ntau qhov chaw. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev loj hlob sai ntawm kev lag luam, daim ntawv thov kev cia siab ntawm emery yuav dav dua.
