Dab tsi yog qhov Basic Crystal Structure
Silicon carbide 88% feem ntau yog tsim los ntawm silicon (Si) thiab carbon (C) atoms teem rau hauv lub zog covalent siv lead ua lattice. Txhua lub atom silicon yog sib txuas nrog cov pa roj carbon atoms, tsim cov qauv nruj thiab ruaj khov. Qhov kev sib koom ua ke no yog ib qho ntawm cov laj thawj tseem ceeb ntawm silicon carbide nthuav tawm siab hardness thiab thermal kuj. Txawm hais tias qib 88% muaj qib siab me ntsis ntawm impurities dua siab dua - qib purity, nws cov qauv siv lead ua tseem ceeb tseem zoo ib yam.
Yuav ua li cas Crystal Structure pab txhawb kom muaj zog
Lub zog ntawm silicon carbide 88% feem ntau yog los ntawm nws cov tetrahedral crystal bonding qauv, uas tsim muaj zog interatomic bonds uas tiv thaiv deformation, ua rau cov khoom tsis tshua muaj zog thiab hnav resistant. Txawm tias nyob rau hauv kev rov ua dua thermal cycling, cov qauv siv lead ua tseem nyob ruaj khov, tso cai rau kev ua haujlwm zoo ib yam dhau sijhawm.
Lub luag haujlwm ua Impurities Ua Si
Silicon carbide 88% muaj kev tswj hwm qib ntawm impurities, xws li cov pa roj carbon monoxide dawb, silicon oxide, thiab cov hlau me me, muab faib rau hauv cov khoom siv microstructure es tsis yog kev hloov pauv ntawm silicon carbide siv lead ua lattice. Txawm hais tias cov ntsiab lus impurity siab dua tuaj yeem txo qis tshuaj lom neeg ruaj khov piv nrog qib siab dua - purity qib, cov qauv kev ncaj ncees tseem txaus rau feem ntau cov ntawv thov kev lag luam.
Yuav ua li cas Particle Structure thiab loj cuam tshuam kev ua tau zoo
Tshaj li cov qauv siv lead ua, particle morphology thiab qhov loj me yog qhov tseem ceeb ntawm cov qauv. Uniform particle loj thiab tswj cov txheej txheem crushing pab ua kom paub tseeb tias tus cwj pwm sib cais thiab kev ua haujlwm zoo ib yam hauv cov txheej txheem metallurgical. Cov qauv particle tsis zoo lossis kev nplua ntau dhau tuaj yeem cuam tshuam tsis zoo rau cov khoom siv thiab kev ua haujlwm.
Vim li cas tus qauv Suits Industrial Siv
Kev sib xyaw ua ke ntawm kev sib raug zoo covalent, ruaj khov siv lead ua lattice, thiab kev tswj cov khoom tsis huv ua rau silicon carbide 88% structurally zoo suited rau kev lag luam ib puag ncig. Nws cov qauv txhawb nqa siab hardness, thermal stability, thiab tsis kam hnav thiab thermal shock, tso cai rau kev ua haujlwm zoo ib yam tsis muaj tus nqi siab dua ntawm ultra-siab- qib purity.
