Guryaha alaabta：
Qalabka ugu muhiimsan ee jirka iyo kiimikooyinka: barta dhalaalka ee zinc waa 419.5 ° C, barta kulaylku waa 907 ° C, cufnaanta 0 ° C waa 7.13g / cm3. Zinc wuu jabaa heerkulka caadiga ah. Marka la kululeeyo 100 ° C ilaa 150 ° C, zinc waxaa lagu cadaadi karaa taarikada khafiifka ah ama waxaa lagu dhejin karaa fiilooyinka birta ah, laakiin marka heerkulku ka sarreeyo 250 ° C, waxay luminaysaa ductility.
Zinc waxay la falgali kartaa asiidh, saldhigyo iyo milix si ay u sameeyaan milix cusub. Dusha sare waxay la falgashaa ogsijiin, kaarboon laba ogsaydh, iyo biyaha hawada ku jira si ay u sameeyaan zinc carbonate asaasi ah oo cufan, kaas oo ka ilaalinaya badeecada in la ogsixiyo.
Waa mamnuuc in la isticmaalo baakadaha iyo agabka lagu qaado aashitada, alkali, milixda iyo waxyaalaha kale ee daxalka leh ee Zinc, waana in lagu kaydiyaa bakhaar qallalan, hawo leh, oo aan qudhun lahayn, lagana ilaaliyo roobka. Heerkulka dhalaalka ee zinc waa inuusan dhaafin 500 ℃ si loo yareeyo luminta oksaydhka iyo luminta isbeddelka. Waa inaysan la xiriirin birta iyo biraha kale ee waxyeelada leh marka ay dhalaaleyso si looga fogaado wasakheynta alaabta. Zinc oxide ayaa laga soo saari doonaa dusha sare ee xalka zinc inta lagu jiro dhalaalka. Ammonium chloride waxaa loo isticmaali karaa samaynta slag si loo hagaajiyo heerka isticmaalka ee zinc. Haddii badeecooyinka zinc-ga ah ay qoyan yihiin roobka, waa in la qalajiyo ka hor inta aan lagu darin dareeraha dhalaalay, si looga fogaado "qarax" si ay u waxyeelleeyaan dadka oo ay u dhaawacaan qalabka.
