Carbide ya Silicon (SiC) nibikoresho byubutaka bikura kenshi nka kristu imwe ya progaramu ya semiconductor. Bitewe nibintu byihariye biranga no gukura kwa kristu imwe, ni kimwe mu bikoresho biramba cyane ku isoko. Uku kuramba kurenze kure imikorere yumuriro wamashanyarazi.
Kuramba kumubiri
Kuramba kwa SiC kugaragazwa neza mugusuzuma ibyakoreshejwe muburyo bwa elegitoronike: sandpaper, extrait ipfa, plaque zitagira amasasu, disiki ya feri ikora cyane, hamwe na disike yaka umuriro. SiC izashushanya ikintu gitandukanye no gushushanya ubwacyo. Iyo ikoreshejwe muri disiki ya feri ikora cyane, kurwanya kwabo kumara igihe kirekire mubidukikije bikaze bishyirwa mubizamini. Kugirango ukoreshwe nk'isasu ridafite amasasu, SiC igomba kuba ifite imbaraga nyinshi z'umubiri n'ingaruka.
Kuramba Kumashanyarazi namashanyarazi
SiC izwiho kutagira imiti; ntaho ihuriye n’imiti ikaze cyane, nka alkalis nu munyu ushongeshejwe, kabone niyo ihura nubushyuhe bugera kuri 800 ° C. Bitewe no kurwanya ibitero by’imiti, SiC ntishobora kwangirika kandi irashobora kwihanganira ibidukikije bikaze birimo guhura n’umwuka w’amazi, amazi y’umunyu, n’imiti itandukanye.
Bitewe ningufu zayo nyinshi, SiC irwanya cyane ihungabana rya electromagnetic ningaruka zangiza imirasire. SiC nayo irwanya kwangirika kurwego rwimbaraga zirenze Si.
Kurwanya Ubushyuhe
Kurwanya SiC guhangana nubushyuhe nubundi buryo bukomeye buranga. Iyo ikintu gihuye nubushyuhe bukabije bukabije, ihungabana ryumuriro ribaho (nukuvuga, mugihe ibice bitandukanye byikintu biri mubushyuhe butandukanye). Nkibisubizo byubushyuhe buringaniye, igipimo cyo kwaguka cyangwa kugabanuka bizatandukana hagati yibice bitandukanye. Ubushyuhe bukabije bushobora gutera kuvunika mubikoresho byoroshye, ariko SiC irwanya cyane izo ngaruka. Kurwanya ubushyuhe bwumuriro wa SiC nigisubizo cyubwinshi bwumuriro mwinshi (350 W / m / K kuri kristu imwe) hamwe no kwaguka kwinshi ugereranije nubwinshi bwibikoresho bya semiconductor.
Ibyuma bya elegitoroniki bya SiC (urugero, MOSFETs na Schottky diode) bikoreshwa mubisabwa hamwe nibidukikije bikaze, nka HEV na EV, kubera kuramba. Nibikoresho byiza cyane byo gukoreshwa muri semiconductor bisaba gukomera no kwiringirwa bitewe nubushobozi bwumubiri, imiti, n’amashanyarazi.
