Inkcazelo emfutshane:

I-Silicon carbide luhlobo olutsha lweekeramics ezinexabiso eliphezulu lokusebenza kunye neempawu ezintle zezinto eziphathekayo. Ngenxa yeempawu ezinje ngokuqina okuphezulu kunye nokuqina, ukumelana nobushushu obuphezulu, ukuguquguquka okukhulu kwe-thermal kunye nokuxhathisa ukubola kweekhemikhali, iSilicon Carbide inokumelana nayo yonke imichiza ephakathi. Ke ngoko, i-SiC isetyenziswa kakhulu kwimigodi yeoli, kwimichiza, koomatshini kunye ne-airspace, nkqu amandla enyukliya kunye nomkhosi banemfuno zabo ezikhethekileyo kwi-SIC. Esinye isicelo esiqhelekileyo esinokusinika amakhonkco okutywina epompo, i-valve kunye nezixhobo zokukhusela njl.
