Hafnium tetrachloride | HfCl4 phofo | CAS 13499-05-3 | theko ea fektheri

Tlhaloso e Khutšoanyane:

Hafnium tetrachloride e na le lits'ebetso tsa bohlokoa e le selelekela sa hafnium oxide, se thusang bakeng sa organic synthesis, lisebelisoa tsa nyutlelie, le ho beoa ha filimi e tšesaane, e totobatsang ho feto-fetoha ha eona le bohlokoa ba eona mafapheng a fapaneng a mahlale.

Kopo

Hafnium Dioxide Precursor: Hafnium tetrachloride e sebelisoa haholo-holo e le selelekela sa ho hlahisa hafnium dioxide (HfO2), thepa e nang le thepa e ntle ea dielectric. HfO2 e sebelisoa haholo lits'ebetsong tsa dielectric tse phahameng tsa k bakeng sa li-transistors le li-capacitor indastering ea semiconductor. HfCl4 e bohlokoa ha ho etsoa lisebelisoa tsa elektronike tse tsoetseng pele ka lebaka la bokhoni ba eona ba ho etsa lifilimi tse tšesaane tsa hafnium dioxide.
Sehlahisoa sa motsoako oa lintho tse phelang: Hafnium tetrachloride e ka sebelisoa e le sesosa sa karabelo e fapaneng ea organic synthesis, haholo olefin polymerization. Lintho tsa eona tsa Lewis acid li thusa ho theha li-intermediate tse sebetsang, ka hona li ntlafatsa ts'ebetso ea karabelo ea lik'hemik'hale. Kopo ena e bohlokoa tlhahisong ea li-polymer le metsoako e meng ea manyolo indastering ea lik'hemik'hale.
Tšebeliso ea Nyutlelie: Ka lebaka la karolo ea eona e phahameng ea ho monya neutron, hafnium tetrachloride e sebelisoa haholo lits'ebetsong tsa nyutlelie, haholo-holo lithupeng tsa taolo ea li-reactor tsa nyutlelie. Hafnium e khona ho monya li-neutron ka katleho, kahoo ke sesebelisuoa se loketseng ho laola tšebetso ea fission, e thusang ho ntlafatsa polokeho le katleho ea tlhahiso ea matla a nyutlelie.
Thin Film Deposition: Hafnium tetrachloride e sebelisoa lits'ebetsong tsa lik'hemik'hale tsa mouoane (CVD) ho etsa lifilimi tse tšesaane tsa thepa e thehiloeng hafnium. Lifilimi tsena li bohlokoa lits'ebetsong tse fapaneng, ho kenyelletsa le li-microelectronics, optics, le liphahlo tse sireletsang. Bokhoni ba ho kenya junifomo, lifilimi tsa boleng bo holimo li etsa hore HfCl4 e be ea bohlokoa lits'ebetsong tse tsoetseng pele tsa tlhahiso.
