Silicon Carbide imapezeka mumitundu iwiri, yolumikizidwa ndi sintered. Kuti mudziwe zambiri panjira ziwirizi chonde titumizireni imelo[imelo yotetezedwa]
Zida zonsezi ndi zolimba kwambiri komanso zimakhala ndi matenthedwe apamwamba kwambiri. Izi zapangitsa kuti silicon carbide igwiritsidwe ntchito ponyamula ndi kuyika zosindikizira pomwe kulimba kowonjezereka ndi kuwongolera kumapangitsa kuti chisindikizo chizigwira bwino ntchito.
Reaction bonded silicon carbide (RBSC) ili ndi katundu wabwino pamatenthedwe okwera ndipo imatha kugwiritsidwa ntchito pokana.
Zida za silicon carbide zimawonetsa kukokoloka kwabwino komanso kukana kwa abrasive, zinthuzi zitha kugwiritsidwa ntchito mosiyanasiyana monga ma nozzles opopera, ma nozzles owombera ndi zida zamkuntho.
Ubwino waukulu ndi Katundu wa Silicon Carbide Ceramics:
l High matenthedwe madutsidwe
l Coefficient yokulirapo yamafuta ochepa
l Kuyimitsa kwambiri kutentha kwamafuta
l Kuuma kwambiri
l Semiconductor
l Refractive index wamkulu kuposa diamondi

Silicon Carbide Production
Silicon Carbide imachokera ku ufa kapena tirigu, wopangidwa kuchokera ku kuchepetsa mpweya wa silika. Amapangidwa ngati ufa wabwino kapena waukulu womangika, womwe umaphwanyidwa. Kuti ayeretse (kuchotsa silika) amatsukidwa ndi hydrofluoric acid.
Pali njira zitatu zazikulu zopangira malonda. Njira yoyamba ndikusakaniza ufa wa silicon carbide ndi zinthu zina monga galasi kapena zitsulo, izi zimachitidwa kuti gawo lachiwiri ligwirizane.
Njira ina ndi kusakaniza ufa ndi carbon kapena silicon zitsulo ufa, ndiyeno anachita omangika.
Pomaliza, ufa wa silicon carbide ukhoza kuchulukitsidwa ndikulowetsedwa kudzera pakuwonjezera kwa boron carbide kapena zida zina zopangira sintering kupanga zoumba zolimba kwambiri. Ndikoyenera kudziwa kuti njira iliyonse ndiyoyenerana ndi ntchito zosiyanasiyana.
Kuti mumve zambiri za Reaction Bonded Silicon Carbide Ceramics chonde titumizireni imelo[imelo yotetezedwa]
