Kukula kwa msika ndi mphamvu zopangira hafnium tetrachloride yamagetsi ku China zikukulirakulira nthawi zonse.
Malo Ofufuzira Makampani Oganiza Zatsopano ku China Atulutsidwa pa Marichi 5, 2026
Hafnium tetrachloride yamagetsi imatanthauza hafnium tetrachloride yoyera kwambiri yokhala ndi chiyero cha 99.95% kapena kuposerapo.
Hafnium tetrachloride, ndi njira ya molekyuluHfCl4ndipo kulemera kwa mamolekyulu a 320.302, ndi ufa woyera wa kristalo. Ndi wowononga ndipo ukhoza kuwotcha maso ndi khungu. Umakwiyitsanso dongosolo la kupuma. Uli ndi malo osungunuka a 320°C ndipo ukhoza kusungunuka. Umasungunuka mosavuta mu zinthu zachilengedwe monga methanol ndi acetone. Umayanjana ndi madzi kuti utulutse mpweya woipa. Ndi wosalala ndipo umawola mosavuta ukakumana ndi mpweya ndipo uyenera kusungidwa mu chidebe chotsekedwa.
"Kafukufuku Wapadera wa Msika wa Electronic Grade Hafnium Tetrachloride wa 2025 China ndi Lipoti la Malingaliro a '15th Five-Year Plan' la Enterprise" lotulutsidwa ndi New Thinking Industry Research Center, hafnium tetrachloride yamagetsi imagwiritsidwa ntchito kwambiri mumakampani opanga ma semiconductor ngati zinthu zoyambira semiconductor. Imayikidwa ndikukulitsidwa ngati mafilimu opyapyala okhala ndi hafnium pogwiritsa ntchito njira monga atomic layer deposition (ALD) ndi chemical vapor deposition (CVD). Mafilimu opyapyala okhala ndi Hafnium ali ndi dielectric constant yapamwamba, zomwe zimapangitsa kuti akhale amodzi mwa zida zofunika kwambiri popanga gate dielectric layer ya transistors yaying'ono, yogwira ntchito kwambiri. Hafnium tetrachloride yamagetsi imatha kukwaniritsa njira yopititsira patsogolo njira zopangira chip zomwe zimachepa nthawi zonse, ndipo malo ake amsika akukulirakulira nthawi zonse. Kuphatikiza apo, chifukwa cha mawonekedwe ake abwino kwambiri, mawonekedwe amakina, komanso kukhazikika kwa kutentha, hafnium tetrachloride yamagetsi ingagwiritsidwenso ntchito popanga mafilimu opyapyala, ma LED amphamvu kwambiri, zida zamagetsi zapafupi ndi infrared, ndi ma ceramics otentha kwambiri.
Ubwino wa ukadaulo woyeretsa umakhudza mwachindunji kuyera ndi kuchuluka kwa hafnium tetrachloride yamagetsi. M'zaka zaposachedwa, chiwerengero cha ma patent okhudzana ndi njira yoyeretsera ndi zida zopangira hafnium tetrachloride yamagetsi ku China chakhala chikukwera, kuphatikizapo "chipangizo chokonzekera hafnium tetrachloride yamagetsi" ndi "njira yoyeretsera hafnium tetrachloride yamagetsi".
Mu Meyi 2025, chilengezo cha chilolezo cha patent chinaperekedwa cha "njira yoyeretsera hafnium tetrachloride yamagetsi". Pansi pa chitetezo cha mpweya wosagwira ntchito, hafnium tetrachloride yosaphika imayikidwa mu boti la quartz, ndipo kudzera mu njira monga kutsuka, kutentha, kuyeretsa sublimation, ndi kusonkhanitsa kuziziritsa, zinthu za hafnium tetrachloride yamagetsi zokhala ndi chiyero cha 5N ndi 6N zitha kupezeka.
Mumsika waku China,Ukadaulo wa UrbanMines.Ochepa makamaka amafufuza, amapanga, ndikupereka zinthu za hafnium tetrachloride zamagetsi zokhala ndi ukhondo wa ≥99.9%, 99.95%, ndi ≥99.99%.
Akatswiri amakampani ku Newthink, mphamvu yopangira hafnium tetrachloride yamagetsi ku China ikukulirakulirabe. Mu Meyi 2025, National Environmental Protection Administration ya China idavumbulutsa kuti lipoti la kukhudzidwa kwa chilengedwe la "Semiconductor New Materials Pilot Plant Project" liyenera kuvomerezedwa ndikulengezedwa, ndipo makampani ena otsogola mumakampaniwa akukulitsanso msika wa hafnium tetrachloride yamagetsi.
