Zirconium(Zr) uyehafnium(Hf) isimbi mbiri dzakakosha dzisingawanzo.Muzvisikwa, zirconium inonyanya kuwanikwa mu zircon (ZrO2) uye zircon (ZrSiO4).Iko hakuna yakaparadzana mineral ye hafnium muzvisikwa, uye hafnium inowanzogara pamwe ne zirconium uye iripo mu zirconium ores.Hafnium uye zirconium iri muchikamu chechina cheiyo periodic tafura yezvinhu, ine zvinhu zvakafanana.Nekuda kweiyo atomic radii yakafanana, kuparadzaniswa kwemakemikari kwakaoma kwazvo.Sezvo shoko rinoenda, 'Kana pane zirconium, pane hafnium, uye kana pane hafnium, pane zirconium', kuratidza 'kunzwirana tsitsi' kwe "hama" mbiri dze zirconium uye hafnium.
Iyo tekinoroji yekuparadzanisa ye zirconium uye hafnium iri kuramba ichikura.Kubva pakubikira chlorination process, kupatsanurwa kwemoto, kubviswa kwekuparadzaniswa kwe zirconium uye hafnium kune ikozvino yakanyorova uye yekuparadzana kwemoto, iyo yekuparadzanisa mhedzisiro ye zirconium uye hafnium yakagadziridzwa, zvichikonzera kuwedzera kunoramba kuripo mukuchena kwezvigadzirwa zvepasi.
Precursors ine zirconium uye hafnium inowanzoshandiswa mumunda wezvigadzirwa kana sezvinokonzera muindasitiri ye petrochemical.Zirconium chloride (ZrCl4,anozivikanwawo sezirconium tetrachloride) inogona kugadzirwa nekunyungudutsa zircon nekudzikisa kabhoni uye chlorination.Hafnium chloride(HfCl4, inozivikanwawo sehafnium tetrachloride) inowanzogadzirwa ne oxidizing hafnium, carbon, uye ipapo chlorinating.Zirconium chlorideuyehafnium chloridezvinhu zvakakosha zvekugadzira maprecursors ane zirconium uye hafnium, ayo anoshandiswa zvakanyanya muaerospace, petrochemical, nuclear uye mamwe minda.
Kushandisa high-purityzirconium tetrachlorideuye hafnium tetrachloride sezvinhu zvakasvibiswa, zvigadzirwa zvakadai se n-propanol zirconium/hafnium, n-butanol zirconium/hafnium, tert butanol zirconium/hafnium, ethanol zirconium/hafnium, dichlorodicenyl zirconium/hafnium, uye bis (n-butylenecyclic)hafnium dichlorideinogonawo kugadzirwa.Izvi zvigadzirwa zvinogona zvakare kushanda sehafnium uye zirconium masosi ehuputi deposition uye ceramic precursors, pamwe neorganic synthesis catalysts.Shang hai Epoch zvinhu zvinogona kupa mapeji ekurongedza kubva kune reagent giredhi kusvika kumaindasitiri giredhi, kusangana neakasiyana mashandisirwo akadai sekuyedza kwesainzi, zvidyarwa zvekutyaira, uye kugadzira.Dzvanya pane iyi link kuti utsvage ruzivo rwechigadzirwa chakakodzera kuti uone ruzivo rwakadzama.
