6N Silicon Carbide Powder ya Kukula kwa PVT SiC

6N Silicon Carbide Powder ya PVT SiC Growth Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Semicera's 6N Silicon Carbide Powder for PVT SiC Growth ndi chinthu choyera kwambiri chomwe chimapangidwira kukula kwa kristalo munjira ya Physical Vapor Transport (PVT). Ndi chiyero cha 6N, ufa wamtengo wapatali wa SiC umatsimikizira kugwira ntchito bwino mu semiconductor ndi ntchito zapamwamba zakuthupi. Semicera's silicon carbide powder imapereka kusasinthika kwapadera, kukhazikika kwamafuta ambiri, komanso zotsatira zodalirika za kukula kwa kristalo wa SiC, ndikupangitsa kuti ikhale chisankho choyenera paukadaulo wapamwamba kwambiri komanso kugwiritsa ntchito mafakitale.

Zopangira zomwe zimagwiritsidwa ntchito popanga tona nthawi zambiri zimaphatikizapo flake graphite, petroleum coke ndi inki yamwala ya microcrystalline. Kukwera kwa chiyero cha graphite, kumapangitsanso mtengo wogwiritsira ntchito. Njira zoyeretsera graphite zitha kugawidwa m'njira zakuthupi ndi njira zama mankhwala. Njira zoyeretsera thupi zimaphatikizapo kuyandama ndi kuyeretsa kutentha kwambiri, ndipo njira zoyeretsera mankhwala zimaphatikizapo njira ya acid-base, njira ya hydrofluoric acid ndi njira yowotcha ya chloride.

Pakati pawo, njira yoyeretsera kutentha kwapamwamba ingagwiritse ntchito malo osungunuka kwambiri (3773K) ndi malo otentha a graphite kuti akwaniritse 4N5 ndi chiyero chapamwamba, chomwe chimaphatikizapo evaporation ndi umuna wa zonyansa ndi malo otsika otentha, kuti akwaniritse cholinga cha kuyeretsedwa [6]. Ukadaulo wofunikira wa toner yoyera kwambiri ndikuchotsa zonyansa. Kuphatikizidwa ndi mawonekedwe a kuyeretsedwa kwa mankhwala ndi kuyeretsedwa kwa kutentha kwakukulu, njira yapadera yoyeretsera kutentha kwa kutentha kwa thermochemical yopangidwa ndi zigawo zikuluzikulu imatengedwa kuti ikwaniritse kuyeretsedwa kwa zipangizo za tona, ndipo chiyero cha mankhwala chikhoza kukhala choposa 6N.
