Zirconium(Zr) kunyehafnium(Hf) zintsimbi ezimbini ezibalulekileyo ezinqabileyo. Ngokwendalo, i-zirconium ikhona ikakhulu kwi-zircon.ZrO2) kunye ne-zircon (ZrSiO4). Ayikho iminerali eyahlukileyo ye-hafnium kwindalo, kwaye i-hafnium ihlala ihlala kunye ne-zirconium kwaye ikhona kwi-zirconium ores. I-Hafnium kunye ne-zirconium zifumaneka kwi-subgroup yesine ye-periodic table yezinto, ezineempawu ezifanayo. Ngenxa yeradiya ye-athomu efanayo, ukuhlukana kweekhemikhali kunzima kakhulu. Njengoko ilizwi lihamba, 'Ukuba kukho i-zirconium, kukho i-hafnium, kwaye ukuba kukho i-hafnium, kukho i-zirconium', ebonisa 'imfesane' yababini 'abazalwana' be-zirconium kunye ne-hafnium.
Itekhnoloji yokwahlula i-zirconium kunye ne-hafnium nayo ihlala iphuhliswa. Ukususela kwinkqubo yokubilisa i-chlorination, ukuhlukana komlilo, ukuhlukana kwe-extraction ye-zirconium kunye ne-hafnium ukuya kumanzi akhoyo kunye nokuhlukana komlilo, umphumo wokuhlukana kwe-zirconium kunye ne-hafnium uphuculwe, okubangelwa ukunyuka okuqhubekayo kokucoceka kweemveliso ezisezantsi.
I-precursors equkethe i-zirconium kunye ne-hafnium isoloko isetyenziswa kwintsimi yezinto eziphathekayo okanye njenge-catalysts kwi-petrochemical industry.Zirconium chloride (I-ZrCl4,kwaziwa njengezirconium tetrachloride) inokuveliswa ngokunyibilikisa i-zircon ngokunciphisa i-carbon kunye ne-chlorination.IHafnium chloride(HfCl4, kwaziwa njengei-hafnium tetrachloride) idla ngokuveliswa nge-oxidizing hafnium, carbon, kunye ne-chlorinating.Zirconium chloridekwayeihafnium chloridezibalulekile izinto ezikrwada zokudibanisa ii-precursors ezine-zirconium kunye ne-hafnium, ezisetyenziswa kakhulu kwi-aerospace, i-petrochemical, inyukliya kunye nezinye iindawo.
Ukusebenzisa ubunyulu obuphezuluzirconium tetrachloridekunye ne-hafnium tetrachloride njengezinto eziluhlaza, iimveliso ezifana ne-n-propanol zirconium / hafnium, n-butanol zirconium / hafnium, tert butanol zirconium / hafnium, ethanol zirconium / hafnium, dichlorodicenyl zirconium / hafnium, kunye ne-bis (n-butylcyclene)ihafnium dichlorideinokwenziwa kwakhona. Ezi mveliso zinokusebenza njengemithombo ye-hafnium kunye ne-zirconium yokubeka umphunga kunye ne-ceramic precursors, kunye ne-organic synthesis catalysts. I-Shang hai Epoch imathiriyeli inokubonelela ngeenkcukacha zokupakisha ukusuka kwibakala le-reagent ukuya kwibakala loshishino, ukuhlangabezana nezicelo ezahlukeneyo ezifana novavanyo lwesayensi, izityalo zokulinga, kunye nemveliso. Cofa kwikhonkco ukukhangela iinkcukacha ezifanelekileyo zemveliso ukujonga ulwazi oluneenkcukacha.
