Kev siv loj ntawm Silicon Carbide

Dub silicon carbide yog tsim los ntawm quartz xuab zeb thiab roj av coke silica ua cov ntaub ntawv tseem ceeb los ntawm kev kub kub smelting nyob rau hauv lub qhov cub tsis kam. Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, nws lub zog txhua yam yog siab dua corundum, thiab nws yog nkig thiab ntse. Ntsuab silicon carbide yog tsim los ntawm roj av coke thiab silica raws li cov ntaub ntawv tseem ceeb, nrog ntsev ntxiv ua ib qho ntxiv, thiab smelted ntawm qhov kub thiab txias nyob rau hauv lub qhov cub tsis kam. Nws hardness yog nruab nrab ntawm corundum thiab pob zeb diamond, thiab nws lub zog txhua yam yog siab dua corundum.

Yog li dab tsi yog qhov tseem ceeb ntawm silicon carbide?
1. Abrasives - Feem ntau vim hais tias silicon carbide muaj siab hardness, tshuaj stability thiab tej yam toughness, silicon carbide yuav siv tau los tsim bonded abrasives, coated abrasives thiab dawb sib tsoo rau txheej txheem iav thiab ceramics. , pob zeb, cam khwb cia hlau thiab qee cov hlau tsis-ferrous, carbide, titanium alloy, high-speed steel txiav cov cuab yeej thiab sib tsoo log, thiab lwm yam.

2. Cov ntaub ntawv refractory thiab corrosion-resistant cov ntaub ntawv --- Feem ntau vim hais tias silicon carbide muaj lub siab melting point (decomposition ntawm decomposition), tshuaj inertness thiab thermal shock kuj, silicon carbide yuav siv tau nyob rau hauv abrasives thiab ceramic khoom firing kilns. Shed phaj thiab saggers, silicon carbide cib rau ntsug lub tog raj kheej distillation furnaces nyob rau hauv zinc smelting kev lag luam, txhuas electrolytic cell linings, crucibles, me me rauv cov ntaub ntawv thiab lwm yam silicon carbide ceramic khoom.

3. Kev siv tshuaj lom neeg-vim silicon carbide tuaj yeem decompose nyob rau hauv molten steel thiab reacts nrog oxygen thiab hlau oxides nyob rau hauv lub molten steel los tsim carbon monoxide thiab silicon-muaj slag. Yog li, nws tuaj yeem siv los ua tus neeg ua haujlwm huv rau smelting steel, uas yog, ua deoxidizer thiab cam khwb cia hlau qauv txhim kho rau steel ua. Qhov no feem ntau siv tsawg purity silicon carbide los txo cov nqi. Nws tseem tuaj yeem siv los ua cov khoom siv raw rau kev tsim silicon tetrachloride.

4. Cov ntawv siv hluav taws xob - siv los ua cov khoom cua sov, cov khoom tsis muaj kab tawm thiab cov khoom siv hluav taws xob siab. Cov khoom siv cua sov xws li silicon carbon rods (tsim rau ntau lub tshuab hluav taws xob ua haujlwm ntawm 1100 txog 1500 ° C), cov ntsiab lus tsis-linear resistor, thiab ntau yam hluav taws xob tiv thaiv li qub.
