Birta kaalshiyamku waa bir iftiin cad oo qalin ah.Birta kaalshiyamka, sida birta aad u firfircoon, waa wakiil awood yareynaya.
Isticmaalka ugu muhiimsan ee kalsiyumka birta ah waxaa ka mid ah: deoxidation, desulfurization, iyo degsiisinta birta samaynta iyo birta shubka;Deoxygenation ee soo saarista biraha sida chromium, niobium, samarium, thorium, titanium, uranium, iyo vanadium;Sida walxo daawaha ah oo loo isticmaalo warshadaha rasaasta si ay u soo saaraan dayactirka baytariyada baabuurta ee bilaashka ah, daawaynta macdanta calcium waxay kordhin kartaa xoogga, hagaajinta caabbinta daxalka, iyo iska caabinta gurguurta;Loo isticmaalo sida deoxidizer biraha kala duwan ee aan birta ahayn, biraha dhulka dhifka ah, iyo biraha refractory;Sida wakiilka alloying (wakiilka isku-dhafka ah) ee soo saarista aluminiumyada aan macdanta lahayn sida aluminium, beryllium, copper, lead, iyo magnesium;Loo isticmaalo sida deoxidizer-ka soo saarista birta saafiga ah ee sare leh iyo alloysyada aan birta ahayn;Ka saarida bismuth ee warshadaha dhalada rasaasta iyo daawaha rasaasta;Iyo qaar kale oo la isticmaalo.
Sifooyinka caadiga ah ee kalsiyumka birta ah waxaa ka mid ah block, chip, iyo qaababka granular, kuwaas oo ka mid ah qaybaha calcium biraha inta badan loo isticmaalo si ay u soo saaraan fiilooyinka xudunta u ah kalsiyum oo loo isticmaalo in wax soo saarka ee birta nadiifsan iyo go'yaal birta;Alloys-ka ugu muhiimsan waa aluminium aluminium calcium iyo calcium magnesium alloy.
