Vim li cas thiaj li silicon carbide hmoov dub thiab ntsuab?

Dub silicon carbide yog tsim los ntawm quartz xuab zeb, roj av coke, thiab siab} Zoo sillica pob zeb, smelted ntawm qhov kub nyob rau hauv lub cub tawg.Ntsuab Silicon CarbideSiv cov ntaub ntawv raw xws li dub silicon carbide, nrog rau kev sib ntxiv ntawm cov ntsev kev lag luam ua ib tug reactant thiab nrawm, thiab tom qab ntawd reacts hauv kev tawm tsam cua. Nws cov xim yog ntsuab, yog li lub npe.

 

Ib cag ntawm cov xim sib txawv, cov zaub mov ntsuab caricon carbide feem ntau muaj ntau cov me nyuam, thaum cov xim dub silicon muaj ntau dua kev ua kom muaj zog dua. Lawv cov ntawv thov sib txawv, txawm li cas los xij. Ntsuab silicon carbide yog purer thiab tawv dua li dub silicon carbide. Nws abrasive siv tau zoo ib yam li cov xim dub silicon

 

Nws tseem dav siv raws li cov khoom siv abrasive rau cov haujlwm ua los ntawm kev tso cai carbide thiab pob zeb diamond. (Ferrano alloy spell network) Dub silicon carmide yog tsim los ntawm quartz xuab zeb, thiab siab} Zoo silica pob zeb, smelted ntawm qhov kub nyob rau hauv ib lub cub tawg.

 

 

Ntsuab silicon carbide thiab dub silicon carbide yog ua los ntawm cov khoom raw zoo sib xws. Muaj ntsev ntxiv ua ib tug reactant thiab accelerator, thiab cov tshuaj tiv thaiv yog nqa tawm hauv kev tiv thaiv rhuab. Nws cov xim yog ntsuab, yog li lub npe. Yuav ua li cas tuaj yeem dub thiab ntsuab silicon carbide yuav txawv? Dhau li ntawm cov xim sib txawv, cov pob zeb dub silicon muaj ntau dua. Vim li cas ob hom Silicon carbide sib txawv, thiab dab tsi yog lawv daim ntawv thov?

 

Ntsuab silicon carbide yog purer thiab tawv dua li dub silicon carbide. Nws abrasive siv tau zoo ib yam li cov xim dub silicon Cov ntaub ntawv Abrasive muaj ntau siv nyob rau hauv workpieces ua los ntawm cemented carbide thiab pob zeb diamond.

 

Vim li cas cov lag luam silicon carbide tshwm xim dub lossis ntsuab? Qee tus ntseeg tias cov xim dub yog vim yog encapsulation ntawm Silicon Carbide muaju los ntawm cov pa roj carbonaceous zoo. Tsis tas li ntawd ntawm cov ntsev, cov sillicon dioxide evaporates sai sai, tawm ntawm cov tshuaj carbonaceous tsis muaj sijhawm txaus kom hnov ​​nrog nws. Qhov no ua rau qee qhov silicon dioxide vapor khiav tawm, tab sis cov tshuaj carbonaceous tsis hnov ​​qhov tseeb li cas los ntawm cov khoom ntsiag to nyob hauv cov muaju silicon carbide muaju. Hauv kev tsim cov ntsuab silicon carmide, nws feem ntau tau hais tias ntau cov ntsev ntxiv rau thaum lub smelting ntawm cov xim dub silicon carbide, li ntsev txhawb txoj kev ua ntsuab ntawm cov khoom. Txawm li cas los xij, tom qab muaj ntau thiab ntev {4 4}} lub ntsiab lus muaj cov khoom lag luam siab (xws li begesium, thiab boron), ntshiab ntsuab silicon carbide tsis tuaj yeem tsim. Hloov siab, yog tias cov ntaub ntawv raw yog cov khoom nyoos heev, ib lub ntsej muag ntsuab ntsuab

 

Qee zaum, ntxiv ntsev thaum lub smelting ntawm cov zaub mov ntsuab silicon tuaj yeem muaj cov kev mob siab, thiab cov cua sov thiab cuam tshuam. Yog li no, yuav tsum tau saib xyuas cov ntsev ntau ntxiv nrog kev siv ntsev thaum lub sijhawm Silicon Carbide smelting txheej txheem.

 

Fanchuang yog ib qho ntawm cov neeg muag khoom ntawm cov khoom lag luam silicon carmide hmoov. Yog koj txaus siab, thov hu rau peb.
