Kaarboon Tetrafluoride
Tetrafluoromethane, oo sidoo kale loo yaqaan kaarboon tetrafluoride, waa fluorocarbon-ka ugu fudud (CF4). Waxay leedahay xoog isku xidhnaan aad u sarreeya sababtoo ah dabeecadda isku xidhka kaarboon-fluorine. Waxa kale oo loo kala saari karaa haloalkane ama halomethane. Sababtoo ah isku xidhka kaarboon-fluorine ee badan, iyo elektaroonigga ugu sarreeya ee fluorine, kaarboonka ku jira tetrafluoromethane wuxuu leeyahay kharash qayb ahaan togan oo muhiim ah kaas oo xoojiya oo soo gaabiya afarta isku xidhka kaarboon-fluorine isagoo bixinaya dabeecad dheeraad ah oo ionic ah. Tetrafluoromethane waa gaas aqalka dhirta lagu koriyo oo awood leh.
Tetrafluoromethane mararka qaarkood waxaa loo isticmaalaa qaboojiye heerkul hooseeya. Waxaa loo isticmaalaa farsamaynta elektaroonigga ah oo keliya ama iyadoo lala kaashanayo oksijiin sida wax lagu nadiifiyo balaasmaha silikoon, silikoon dioxide, iyo nitride silikoon.
