Khoom Description
Silicon carbide (SiC) yog cov khoom siv sib xyaw ua ke ntawm silicon thiab carbon. Nws cov khoom yog nruab nrab ntawm cov ceramics thiab hlau, thiab nws muaj ntau yam zoo heev lub cev thiab tshuaj. Silicon carbide yog ib qho nyuaj heev, nrog rau Mohs hardness ntawm 9.5, thib ob tsuas yog pob zeb diamond, thiab yog ib qho uas feem ntau siv high-hardness abrasive hauv kev lag luam. Silicon carbide muaj lub zog siab thiab tensile lub zog thiab tuaj yeem tiv taus kev ntxhov siab loj. Silicon carbide muaj kev ruaj ntseg zoo heev ntawm qhov kub thiab txias thiab tuaj yeem tiv taus qhov kub txog li 2700 degree, ua rau nws yog ib qho khoom zoo heev refractory. Silicon carbide muaj cov thermal conductivity zoo, uas yog qhov zoo rau kev hloov pauv thiab tawg ntawm tshav kub. Silicon carbide tuaj yeem ua haujlwm ruaj khov hauv ntau yam tshuaj lom neeg xws li acids, alkalis, thiab ntsev, thiab muaj kev tiv thaiv corrosion zoo.
Silicon carbide muaj ntau cov qauv siv lead ua, feem ntau yog -SiC (hexagonal system) thiab -SiC (cubic system). Silicon carbide feem ntau yog npaj los ntawm silica txo txoj kev, uas sib tov high-purity silica thiab roj av coke thiab reacts lawv kub.
Silicon carbide yog ib qho nyuaj heev thiab feem ntau siv high-hardness abrasive hauv kev lag luam. Nws tuaj yeem siv los ua ntau yam cuab yeej abrasive, xws li kev sib tsoo log, ntawv xuab zeb, siv xuab zeb, roj zeb, sib tsoo blocks, sib tsoo taub hau, thiab lwm yam. Cov cuab yeej abrasive no ua lub luag haujlwm tseem ceeb hauv kev sib tsoo, polishing thiab txiav cov ntaub ntawv xws li hlau, iav, ceramics, thiab pob zeb. Vim nws cov hardness siab thiab zoo hnav tsis kam, silicon carbide abrasives tuaj yeem muab kev txiav zoo thiab zoo zoo. Yog li ntawd, silicon carbide abrasives yog dav siv nyob rau hauv precision sib tsoo thiab polishing ntawm hlau, ceramics, thiab iav kom tau raws li qhov yuav tsum tau nruj me ntsis rau cov nto roughness thiab precision ntawm cov ntaub ntawv. High-purity silicon carbide ib leeg siv lead ua kuj tseem siv tau los tsim cov cuab yeej txiav hlau, tshwj xeeb tshaj yog hauv kev ua cov khoom siv hluav taws xob (xws li ib leeg siv lead ua silicon, polycrystalline silicon) thiab piezoelectric crystals. Cov cuab yeej txiav hlau no tuaj yeem ua kom muaj kev txiav txim siab siab thaum txo kev puas tsuaj rau cov khoom. Tsis tas li ntawd, silicon carbide abrasives kuj tuaj yeem siv los ua kev sib tsoo pastes, nrog rau kev sib tsoo thiab polishing ntawm ib leeg siv lead ua silicon, polycrystalline silicon hauv cov khoom photovoltaic thiab piezoelectric crystals hauv kev lag luam electronics.
Hauv cov ntsiab lus, raws li cov khoom siv tseem ceeb hauv kev lag luam abrasive, silicon carbide muaj cov ntawv thov dav dav thiab cov nqi tseem ceeb. Nws tuaj yeem tsis tsuas yog txhim kho kev ua tau zoo thiab qhov tseeb ntawm cov ntaub ntawv, tab sis kuj ua tau raws li cov kev cai nruj rau cov khoom nto zoo.
