Hafnium (iv) chloridendi gawo lofunikira popanga chitsulo cha hafnium. Amagwiritsidwa ntchitonso kukonza mankhwala ambiri a Hafnium.
M'munda wa zinthu za sayansi,Hafnium (iv) chloridendi chinthu chofunikira kwambiri pakukonzekera kwa Hafnium Ordoys.KamvuluMakina owonjezera amagwiritsidwa ntchito kwambiri m'matanthwe owonda a Aerospace, monga Turbine masamba ndi zipinda zoyaka bwino, chifukwa cha kuchuluka kwawo kukakana ndi kukana kwawo. Amatha kupirira kupsinjika kwamakina ndi kukokoloka kwamankhwala motentha kwambiri madera ambiri, kuonetsetsa kuti ntchito yoyendetsa ndege idalire.
Makampani amagetsi: Ndi chinthu chofunikira chopangira dielect wamba dielect zambiri. Ndi chitukuko chopitilira muyeso cha semiconduct kupita kwa miniaturization, zofunikira zopangira zida zikuyamba kuvuta kwambiri. Zipangizo zophatikizika ndi Hafnium Tetrachloride imatha kusintha magetsi oyendetsa bwino, kuchepetsa kukopera, kuthandizira tchipisi ochepetsetsa, ndikulimbikitsa kukweza kwa makompyuta.
Kupanga: Kukonzekera zokonda zapadera zomwe zili ndi Hafnium, zomwe zimakhala ndi mphamvu zapadera, kuuma, komanso kutentha kwambiri. Amakhala ndi magwiridwe antchito abwino pakudula zida, nkhungu, ndi misozi ya mafakitale, kuwonjezera moyo wawo wautumiki ndikuwongolera bwino ntchito.
Hafnium oxide oxide: HFCL₄ amagwiritsidwa ntchito ngati chotsogola kuti apange hafnium oxide (hfou), omwe ali ndi mitundu yosiyanasiyana ya ma valt-k seticles a zida semiconductor.
Chothandizira pakupanga spnthesis: kutsanzira kwa hafnium kugwiritsidwa ntchito ngati chothandizira muzochitika zachilengedwe, makamaka mu njira ya polymerization.
Mankhwala mkangano (CVD): HFCL₄ imagwiritsidwa ntchito mu mankhwala opatsirana a mankhwala kuti apereke mafilimu omwe ali ndi mafilimu, omwe ndi ofunikira pakupanga microlectronics ndi tekinoloje yowonda.

Kafukufuku ndi Develoum
Kusungidwa mu malo ogulitsira komanso owuma.
Hafnium chloride (hfcl₄) ayenera kusungidwa mosamala kuti asakhale okhazikika komanso kupewa kuchepa. Nawa maupangiri ogwiritsira ntchito hafnium chloride:
Chidebe: Sungani Hafnium chloride mu mulifupi ndi zinthu zoyenera, monga galasi kapena pulasitiki zina, kuteteza chitseko cha chinyezi. Pewani kugwiritsa ntchito zitsulo zachitsulo ngati hafnium chloride zokhudzana ndi zitsulo.
Zachilengedwe: zotengera zosungira m'malo ozizira, owuma kutali ndi dzuwa ndi kutentha. Chifukwa choti Hafnium chloride ndi hygroscopic, ndikofunikira kuchepetsa chinyontho.
Mlengalenga: Ngati zingatheke, sungani HAFNANIH Chloride pansi (monga nayitrogeni kapena argon) kuti mupewe hydrolysis mlengalenga.
Zolemba: Zolemba bwino zopezeka ndi dzina la mankhwala, chidziwitso chowopsa, ndi detiifit detifict kuti muwonetsetse bwino ntchito ndi chitetezo.
Kusamala: Chonde tsatirani malangizo onse owopsa popewa posungira zakuthupi posungira ndi kugwiritsa ntchito hafnium chloride, kuphatikizapo kugwiritsa ntchito zida zoyenera (PPE).
Inde, Hafnium chloride (HFCL₄) amatengedwa owopsa. Nazi mfundo zazikuluzikulu za zoopsa zake:
1. Chowononga: hafnium chloride ndikuwononga khungu, maso ndi kupuma thirakiti. Kulumikizana kumatha kuyambitsa mkwiyo ndi kuwotcha.
2. Kuopsa: Kupumira kwa hafnium chloride fumbi kapena nthunzi zimatha kukhala zovulaza ndipo zitha kuyambitsa mavuto. Onetsetsani kuti musapupule fumbi kapena utsi.
3.
4. Zovuta za chilengedwe: Kupweteka kwa hafnium kuvulaza moyo wam'madzi ndipo kuyenera kusamaliridwa ndi chisamaliro kuti chilengedwe.
Chifukwa cha zoopsazi, ma protocol oyenera kuyenera kutsatidwa mukamagwira ma hafnium chloride, kuphatikizapo kugwiritsa ntchito zida zoyenera zoteteza (PPE), kugwira ntchito m'malo onse otetezedwa, ndikutsatira malamulo onse otetezedwa.
ZOTHANDIZA:Hafnium Tetrachloride ayenera kumezedwe mu zotengera zabwino, mabotolo azitsulo wamba kapena mabotolo agalasi amalumikizidwa ndi pulasitiki, kuti asatazo. Zolemba zodziwikiratu za mankhwala ziyenera kuphatikizidwa kunja kwa ma CD, omwe akuwonetsa kuti "Hafnium Tetrachlordide", "zoopsa", "poizoni", komanso nambala ya United Nations kuti mudziwe mwachangu.
Zoyendera:Magalimoto oyendera kuyenera kukhala ndi mpweya wabwino m'malo mwa mpweya wabwino kuti mupewe kudzikundikira kwa mpweya woopsa utatha. Popewa kuwonekera kutentha kwambiri, kuwonekera kwa dzuwa, ndi mvula, kutentha kwambiri kumatha kuyambitsa kuwonjezereka mkati mwa chidebe, zomwe zimayambitsa kutayikira. Kulumikizana ndi madzi amvula kumatha kuyambitsa hydrolysis ya hafnium tetrachloride kupanga zinthu zokolola, zomwe zimatha kunyamula mitengo yamagalimoto ndi magalimoto. Nthawi yoyendera, tikulimbikitsidwa kuyendetsa bwino komanso kuchepetsa mabampu ndi kugwedezeka.
