Isticmaalka Alaabta
Isticmaalka Hafnium waa mid xaddidan sababtoo ah fara badan oo hooseeya. Isticmaalka aasaasiga ah ee hafnium waa warshadaha nukliyeerka, halkaas oo loo isticmaalo ulaha shidaalka si loo xakameeyo fiska marka loo eego qaybta nuugista nuugista ee sare. Si la mid ah zirconium, hafnium waxaa lagu daray niobium iyo carbide si loo soo saaro qalabka heerkulka sare ee foornada iyo qaybaha jet-ka iyo sidoo kale gooyayaasha balaasmaha. Intaa waxaa dheer, hafnium oxide ayaa si sii kordheysa loogu isticmaalayaa in lagu kordhiyo ama lagu beddelo chips-ka microprocessor-ka ee silicone oxide ee codsiyada qaarkood iyo sidoo kale cathodes iyo capacitors (Field et al., 2011). Hafnium waxay leedahay xiriir aad u weyn oo loogu talagalay nuugista neutron-yada gaabis ah. Sifadan, oo ay weheliso xooggeeda iyo iska caabinta daxalka, ayaa ka dhigaysa mid ka sarreeya cadmium, kaas oo sidoo kale loo isticmaalo samaynta ulaha xakamaynta ee reactors nukliyeerka. Isticmaalkaani waxa uu muhiimad gaar ah u leeyahay nooca reactors nukliyeerka ee loo isticmaalo dushooda. Marka la dhaqaajiyo ulaha kantaroolka gudaha iyo ka soo baxa nukliyeerka, falcelinta silsiladda fissionka waa la xakameyn karaa maadaama neutron-yadu ay nuugaan biraha ulaha. Dib-u-dhac ku yimaada ulaha kantaroolka hafnium waa kharashkooda: waxay ku kacaysaa qiyaastii hal milyan oo doolar dhowr darsin ulood oo loogu talagalay isticmaalka hal reactor nukliyeer ah. Ogsajiinta ama nitrogen ee tuubada, sidaas awgeed waxay kordhinaysaa nolosha tuubada vacuum. Tayada Hafnium waxay sidoo kale ka dhigtaa mid ku habboon fiilooyinka nalalka iftiinka iyo, marka lagu daro biraha dhifka ah ee dhulka, sida birta "dhalleysa" ee mish. Hafnium waxa kale oo loo istcimaalaa wax yar sidii wakiilka alooyaynta ee biraha kale oo badan, oo ay ku jiraan birta, titanium, iyo niobium. Lagu helay macdanta iyo nadiifinta birta; loo isticmaalo ulaha kantaroolka ee reactors nukliyeerka iyo soo saarista fiilooyinka nalka iftiinka; laga helay dhammaan macdanta zirconium ka kooban.

Ka ilaali walxaha oksijiinta ee xoogga leh, saldhigyada adag, halogens, fosfooraska, iyo baaruudka. Ku kaydi biyaha hoostooda.
Ilaalinta Badbaadada
Taxadarrada si badbaado leh loo maareeyo
Ma jiro holac furan, NO dhimbiil iyo sigaar cabbin. Ha u soo bandhigin khilaaf ama naxdin. Nidaam xiran, qalab koronto oo aan qarxin boodhka iyo iftiinka. Kahortagga dhigista boodhka. Wax ka qabashada meel hawo fiican leh. Xiro dhar ilaalin ku habboon. Ka fogow taabashada maqaarka iyo indhaha. Iska ilaali samaynta boodhka iyo hawada hawada. Isticmaal aaladaha aan hurinta lahayn. Ka hortag dabka ka dhasha uumiga dareeraha korantada.
