I-Hafnium (iv) chlorideibalulekile ekungeneni kwimveliso ye-hafnium yentsimbi. Isetyenziselwa ukulungiselela ii-hafnium ezininzi.
Kwintsimi yesazinzulu yenzululwazi,I-Hafnium (iv) chlorideyinto ephambili ye-preCoror kwilungiselelo le-Alfnium esulelekileyo.HafniumI-alloys esekwe isetyenziswe ngokubanzi kwicandelo elishushu leenjini ze-aerospace, ezinjengeenkomo ze-turbine, ngenxa yokunganyangeki kobushushu obuphezulu kunye nokunganyangeki kwabo. Banokumelana noxinzelelo lomatshini kunye nokukhukuliseka kwekhemikhali kwiindawo ezinamaqondo obushushu aphezulu, aqinisekisa ukusebenza ngokufuthi kwenqwelomoya.
Umzi-mveliso we-elektroniki: Yinto ebalulekileyo eluhlaza yemveliso yemveliso yesango le-Delectant sesango. Ngokuphuhliswa okuqhubekayo kwezixhobo ze-semicondcuctor ukuya kwi-mineatheric, iimfuno zomsebenzi zesango zisiba mandundu. Izixhobo ezenziwa nge-hafnium tetrachloride zinokuphucula ngokufanelekileyo ukusebenza kohambo, ukunciphisa ukuvuza, ukunceda i-chips kufezekise isantya esiphezulu sekhomputha kunye nokukhuthaza ukuphuculwa kweemveliso ze-elektroniki.
Imveliso ye-ceramic: isetyenziselwa ukulungiselela i-ceramics ekhethekileyo ene-hafnium ye-hafnium, enamandla okhethekileyo, ubunzima, kunye nokunganyangeki kobushushu obuphezulu. Basebenza kakuhle kwizixhobo ezisikiweyo, ukubumba, kunye namashishini eKingn Linengs, ukudlulisa ubomi babo ngenkonzo kunye nokuphucula ukusebenza kwemveliso.
I-Hafnium Oxiyer Precursor: I-HFCL₄ ihlala isetyenziswa njenge-precursor yokuvelisa i-hafnium oxide (HFO), enezinto ezahlukeneyo ezibandakanya iidiko ze-semicondcuctor.
I-Catalyst kwi-synthesic synthesic: i-hafnium chloride inokusetyenziswa njengeyona nto iphambili kwizinto ezithile eziphilayo, ngakumbi kwinkqubo yePolymerizazazazaza.
I-Chemical Vapor Vipotition (i-CVD): I-HFDL₄ isetyenziswa kwi-Vapor yePhekamili yePhekhemikhali yokufaka iifilimu ezineefilimu ze-hafnium, ezibaluleke kakhulu ekwenzeni i-microlectial kunye neTekhnoloji yeFayile yeFayile yeFleyikhi.
Izicelo zeNyukliya: Ngenxa yepropathi ye-neutron efunxa, i-hafnium kunye nemilinganiselo yayo (kubandakanya i-hafnium ye-hafnium chloride) isetyenziswa kwi-nuclear reacces kunye neentonga zokulawula.
Uphando kunye nophuhliso: I-Hafnium ye-Hilor ikwasetyenziswa kwizicelo ezahlukeneyo zophando, ngakumbi kumacandelo eSayensi yezixhobo kunye ne-chemistry yokufunda imingxunya ye-hafnium kunye nezinto zabo.
Igcinwe kwindawo yokugcina impahla eyomileyo neyomileyo.
I-Hafnium Chloride (HFCL₄) kufuneka igcinwe ngononophelo ukugcina uzinzo lwayo kunye nokuthintela ukonakaliswa. Nazi ezinye izikhokelo zokugcina i-hafnium chloride:
Isikhongozeli: Gcina i-hafnium ye-hloride kwizitya ze-airtight ezenziwe ngezinto ezifanelekileyo, ezinjengeglasi okanye iiplasitiki ezithile, ukuthintela ukungena komswakama. Kulumkele ukusebenzisa izitya zensimbi njenge-hafnium ye-hafnium ye-hloride ye-metals.
Imo engqongileyo: Iikhontelo zokugcina kwindawo epholileyo, eyomileyo kude nokukhanya kwelanga ngqo kunye nobushushu. Kuba i-hafnium chloride i-hygroscopic, kubalulekile ukunciphisa ukubonakaliswa komswakama.
I-InErt Atmosphere: Ukuba kunokwenzeka, gcina i-hafnium ye-hloride phantsi kwe-Itroges (njenge-nitrogen okanye i-nitrogen okanye i-argon) ukuthintela i-hydrolysis kunye nokuphendula komswakama emoyeni.
Ileyibhile: Ngokucacileyo iilebheli kwigama leekhemikhali, ulwazi olunobungozi, kunye nomhla wokufumana irisithi ukuze kuqinisekiswe ukuphathwa nokhuseleko olufanelekileyo.
IZIKHOKELO ZOKHUSELEKO: Nceda ulandele zonke izikhokelo ezifanelekileyo zokhuseleko lwezinto ezinobungozi kunye nokugcina kunye nokuphatha i-hafnium chloride, kubandakanya ukusetyenziswa kwezixhobo ezifanelekileyo zokhuselo (PPE).
Ewe, i-hafnium chloride (hfcl₄) ithathwa njengeyingozi. Nazi ezinye iindawo eziphambili malunga neengozi zayo:
I-1. I-Prerosive: I-Hafnium Chloride iyohlisa ulusu, amehlo kunye nephecana lokuphefumla. Unxibelelwano lunokubangela ukucaphukisa kunye nokutsha.
I-2. Ityhefu: inhalation ye-hafrium ye-hafnium chloride okanye i-vapor inokuba yingozi kwaye inokubangela iingxaki zokuphefumla. Qiniseka ukuba uphephe ukuphefumla naluphi na uthuli okanye umsi.
3. Ukuhlawulwa kwakhona: I-Hafnium Chloride i-hygroscopic kwaye ikwazi ukusabela ngokufuma emoyeni ukukhupha i-hydrochloric acid, eyingozi.
I-4. Impembelelo yokusingqongileyo: I-Hafnium Chloride iyingozi kubomi bamanzi kwaye kufuneka ikhutshelwe ngononophelo ukuthintela ungcoliseko lwendalo.
Ngenxa yezi ngozi, iiprothokholi zokhuseleko ezifanelekileyo kufuneka zilandelwe xa uphatha i-hafnium ye-hloride, kubandakanya ukusebenzisa izixhobo ezifanelekileyo zokhuselo (PPE), ukusebenza kuzo zonke izikhokelo ezifanelekileyo zokhuseleko nemigaqo.
Iimfuno zokupakisha:I-Hafnium Tetrachloride ifakwe kwizikhongozeli ezinendlela elungileyo yokutywina, imigqomo ethe tyaba okanye iibhotile zentsimbi ezifakwe kwiplastiki, ukuqinisekisa ukuba akuyi kubakho ukuvuza ngexesha lokuhamba. Iilebheli ezicacileyo zekhemikhali kufuneka zinamathele ngaphandle kokupakishwa, zibonisa ulwazi oluphambili njenge "Hafnium Tetracheride", "Thobela", "onetyhefu" yenombolo yeZizwe eziManyeneyo yokuchonga ngokukhawuleza.
Iimeko zothutho:Izithuthi zothutho kufuneka zibe namaziko afanelekileyo okungena umoya ukuthintela ukuqokelelwa kwegesi enetyhefu emva kokuvuza. Ukuthintela amaqondo obushushu aphezulu, ukuvezwa kwelanga, kunye nemvula, amaqondo obushushu aphezulu kunokubangela ukwanda ngaphakathi kwesikhongozeli, okukhokelela ekuvusweni. Ukudibana kwamanzi emvula kunokubangela i-hydrolysis ye-haftnium ye-tetrachloride ukuvelisa izinto ezinobungozi, ezinokuthintela ukupakisha kunye nezinto zezithuthi. Ngexesha lokuhamba, kuyacetyiswa ukuba kuqhubeke kakuhle kwaye kunciphise amagqabantshintshi kunye nokuzibandakanya.
