Tetrafluoride ya kaboni
Tetrafluoromethane, yomwe imadziwikanso kuti carbon tetrafluoride, ndi fluorocarbon yosavuta kwambiri (CF4). Ili ndi mphamvu yolumikizana kwambiri chifukwa cha mtundu wa mgwirizano wa carbon-fluorine. Ikhozanso kugawidwa m'gulu la haloalkane kapena halomethane. Chifukwa cha ma bond angapo a carbon-fluorine, komanso mphamvu yayikulu kwambiri ya fluorine, kaboni mu tetrafluoromethane ili ndi mphamvu yayikulu yomwe imalimbitsa ndikufupikitsa ma bond anayi a carbon-fluorine popereka mawonekedwe ena a ionic. Tetrafluoromethane ndi mpweya wamphamvu wowonjezera kutentha.
Tetrafluoromethane nthawi zina imagwiritsidwa ntchito ngati firiji yotsika kutentha. Imagwiritsidwa ntchito mu microfabrication yamagetsi yokha kapena kuphatikiza ndi mpweya ngati plasma etchant ya silicon, silicon dioxide, ndi silicon nitride.

Zolemba
1) Deta yonse yaukadaulo yomwe yatchulidwa pamwambapa ndi yanu.
2) Mafotokozedwe ena ndi olandiridwa kuti tikambirane zambiri.
