Kuchena kweupfu hweSiC kuchakanganisa zvakananga kunaka uye mashandiro eSiC single crystal inorimwa nenzira yePVT, uye zvinhu zvekugadzira upfu hweSiC ihupfu hweSi hwakachena uye upfu hweC hwakachena, uye kuchena kweupfu hweC kuchakanganisa zvakananga kuchena kweupfu hweSiC.

Zvinhu zvinoshandiswa mukugadzira toner zvinowanzo sanganisira flake graphite, petroleum coke uye microcrystalline stone ink. Kana graphite yakakwira, kukosha kwayo kunowedzera. Nzira dzekuchenesa graphite dzinogona kukamurwa kuita nzira dzepanyama uye nzira dzemakemikari. Nzira dzekuchenesa physical dzinosanganisira flotation uye high temperature cleansing, uye nzira dzekuchenesa makemikari dzinosanganisira acid-base method, hydrofluoric acid method uye chloride roasting method. Pakati padzo, nzira yekuchenesa temperature yakakwira inogona kushandisa high melting point (3773K) uye boiling point yegraphite kuti iwane 4N5 uye high cleanness, iyo inosanganisira evaporation uye emission of uncleans with low boiling point, kuitira kuti chinangwa chekuchenesa chibudirire [6]. Tekinoroji huru ye high purity toner ndeyekubvisa trace disadvantages. Pamwe chete nehunhu hwe chemical cleansing uye high temperature cleansing, nzira yakasiyana ye composite high temperature cleansing process inoshandiswa kuti iwane high purity toner materials, uye high cleanness yechigadzirwa inogona kupfuura 6N.
