SiC coated suscetpor ke karolo ea bohlokoa e sebelisoang lits'ebetsong tse fapaneng tsa tlhahiso ea semiconductor. Re sebelisa theknoloji ea rona e nang le tokelo ea molao ho etsa hore SiC e koahetsoeng ka suscetpor e be le bohloeki bo phahameng ka ho fetisisa, bohloeki bo botle ba ho roala le bophelo bo botle ba tšebeletso, hammoho le ho hanyetsa lik'hemik'hale tse phahameng le thepa ea botsitso ba mocheso.
Likarolo tsa lihlahisoa tsa rona:
1. Ho hanyetsa mocheso o phahameng oa oxidation ho fihlela ho 1700 ℃.
2. Bohloeki bo phahameng le ho tšoana ha mocheso
3. Ho hanyetsa kutu e ntle haholo: acid, alkali, letsoai le li-reagents tsa manyolo.
4. Boima bo phahameng, bokaholimo bo kopanetsoeng, likaroloana tse ntle.
5. Bophelo bo bolelele ba tšebeletso le bo tšoarellang haholoanyane
