Ntawm no yog cov kev qhia yooj yim ntawm cov txheej txheem:
Cov Ntaub Ntawv Yuav Tsum:
Silica (Sio2)- xuab zeb lossis quartz.
Carbon (c){{0- Feem ntau nyob rau hauv daim ntawv ntawm roj av coke lossis thee.
Khoom siv:
Kev kub siab fais cub.
Theem ntawm tus txheej txheem Achaeson:
Kev npaj Batch:
Sib tov silica thiab carbon rau hauv ib qho kev sib sau ua feem (feem ntau yog li 1 ntu silica rau 2.5 feem carbon los ntawm qhov hnyav).
Them cov qhov cub:
Tso qhov sib xyaw kom sib xyaw hauv qhov cub. Lub qhov cub feem ntau yog cov qauv loj cylindrical muaj peev xwm ncav cuag siab kub.
Thaum Tshav Kub Kub:
Sio 2+3 C → sic +2 co
Thov ib qho muaj zog tam sim no rau cov electrodes hauv qhov cub. Qhov ntsuas kub sab hauv qhov cub nce mus rau kwv yees li 1 600 - 2 500℃({2}}℃f).
Ntawm cov ntsuas kub no, cov tshuaj lom neeg tshuaj lom neeg tshwm sim nyob rau hauv cov pa roj carbon reacts nrog silicon los ua silicon carbide, thiab carbon monoxide li breproduct:
Cua txias thiab khoom:
Tom qab cov tshuaj tiv thaiv tau ua tiav, lub cub tawg kom txias. Qhov tshwm sim yog kev sib xyaw ntawm silicon carbide thiab siv cov carbon.
Silicon carbide tuaj yeem tom qab sib cais siv cov kev siv lub cev thiab txuas ntxiv ua lossis ua kom zoo nyob ntawm qhov xav tau kev coj dawb huv thiab loj.
Lwm txoj hauv kev:
Tshuaj Vauv Vapor Deposition (CVD):Ib txoj hauv kev siv feem ntau los tsim cov yeeb yaj kiab nyias ntawm silicon carbide los ntawm reacting silane (Sihot) nrog cov pa hluav taws kub.
Sintering:Nias cov hmoov ntawm silicon thiab carbon rau hauv pwm thiab tom qab ntawd muab cov cua sov rau lawv kom tsim cov zaub mov silicon carbide.
Refinalive Sintering:Cov qauv no siv cov tshuaj tiv thaiv ntawm silicon thiab cov pa roj carbon ntawm cov kub thiab siab.
Cov Ntawv Thov:
Silicon carbide yog siv nyob rau ntau yam kev siv nrog rau cov khoom siv semiconductor, abrasivesives, thiab raws li cov khoom siv refractory vim nws lub siab thermal conductivity thiab kuj mus rau thermal poob siab.
