Ntsuab silicon carbide feem ntau muaj ntau dua purity piv nrog dub silicon carbide.
Yuav ua li cas Silicon Carbide yog tsim
Silicon carbide feem ntau yog tsim los ntawm kev kub siab - txheej txheem kub hu uaAcheson txheej txheem.
Cov txheej txheem no suav nrog cov cua sov silica xuab zeb thiab cov ntaub ntawv carbon nyob rau hauv lub qhov cub hluav taws xob ntawm qhov kub siab tshaj2000 degree.
Lub hauv paus tshuaj tiv thaiv yog:
SiO₂ + 3C → SiC + 2CO
Thaum cov txheej txheem no, silicon dioxide reacts nrog carbon los tsim silicon carbide crystals.
Cov khoom siv tseem ceeb siv hauv Silicon Carbide ntau lawm
Cov khoom siv tseem ceeb siv hauv kev tsim silicon carbide suav nrog:
- silica xuab zeb
- roj av coke
- sawdust los yog ntoo chips
- ntsev additives (qee zaum siv los txhim kho cov kev mob tshwm sim)
Cov ntaub ntawv no tau muab tso rau hauv lub qhov cub thiab ua kom sov li ob peb teev los ua silicon carbide crystals.
