Ekubeni i-calcium inobudlelwane obuqinileyo kunye ne-oksijeni, isulfure, i-hydrogen, i-nitrogen kunye nekhabhoni kwintsimbi etyhidiweyo, ii-alloys ze-silicon-calcium zisetyenziselwa i-deoxidation, i-degassing kunye nokulungiswa kwesulfure kwintsimbi etyhidiweyo.Isilicon yeCalcium ivelisa isiphumo esinamandla se-exothermic xa ifakwe kwintsimbi etyhidiweyo.I-calcium ijika ibe ngumphunga wekhalsiyam kwintsimbi etyhidiweyo, enefuthe elivuselelayo kwintsimbi etyhidiweyo kwaye iluncedo ekujuleni kwezinto ezifakwayo ezingezizo ezentsimbi.
