Bohloeki ba phofo ea SiC bo tla ama ka ho toba boleng le ts'ebetso ea kristale e le 'ngoe ea SiC e lengoang ka mokhoa oa PVT, 'me lisebelisoa tse tala tsa ho lokisa phofo ea SiC ke phofo ea Si e hloekileng haholo le phofo ea C e hloekileng haholo, 'me bohloeki ba phofo ea C bo tla ama ka ho toba bohloeki ba phofo ea SiC.
Lisebelisoa tse tala tse sebelisoang tlhahisong ea toner hangata li kenyelletsa graphite ea flake, coke ea petroleum le enke ea majoe a microcrystalline. Ha graphite e hloekile haholo, boleng ba tšebeliso boa phahama. Mekhoa ea ho hloekisa graphite e ka aroloa ka mekhoa ea 'mele le mekhoa ea lik'hemik'hale. Mekhoa ea ho hloekisa 'mele e kenyelletsa ho phaphamala le ho hloekisa mocheso o phahameng, 'me mekhoa ea ho hloekisa lik'hemik'hale e kenyelletsa mokhoa oa acid-base, mokhoa oa hydrofluoric acid le mokhoa oa ho besa chloride. Har'a tsona, mokhoa oa ho hloekisa mocheso o phahameng o ka sebelisa ntlha e phahameng ea ho qhibiliha (3773K) le ntlha e belang ea graphite ho fihlela 4N5 le bohloeki bo phahameng, bo kenyeletsang mouoane le ho ntša litšila ka ntlha e tlase ea ho belisa, e le ho fihlela morero oa ho hloekisa [6]. Theknoloji ea bohlokoa ea toner e hloekileng haholo ke ho tlosa litšila tse setseng. Ha e kopantsoe le litšobotsi tsa ho hloekisa lik'hemik'hale le ho hloekisa mocheso o phahameng, mokhoa o ikhethang oa ho hloekisa thermochemical o kopantsoeng o arotsoe ka likarolo ho fihlela ho hloekisoa ha thepa ea toner e hloekileng haholo, 'me bohloeki ba sehlahisoa bo ka ba ho feta 6N.
Tshebetso ea sehlahisoa le likarolo:
1, bohloeki ba sehlahisoa≥99.9999% (6N);
2, botsitso bo phahameng ba phofo ea khabone, tekanyo e phahameng ea graphitization, litšila tse fokolang;
3, granularity le mofuta li ka fetoloa ho latela basebelisi.
Tšebeliso e kholo ea sehlahisoa:
■ Ho kopanngoa ha phofo ea SiC e hloekileng haholo le thepa e 'ngoe ea carbide ea maiketsetso ea mohato o tiileng
■ Holisa litaemane
■ Lisebelisoa tse ncha tsa ho tsamaisa mocheso bakeng sa lihlahisoa tsa elektroniki
■ Thepa ea cathode ea betri ea lithium ea boleng bo holimo
■ Metswako ea tšepe ea bohlokoa le eona ke thepa e tala
