Kukho iindlela ezimbini zokuvelisa i-metallic calcium. Enye yindlela ye-electrolytic, evelisa i-calcium yensimbi enobunyulu ngokubanzi ngaphezu kwe-98.5%. Emva kwe-sublimation eyongezelelweyo, inokufikelela kubunyulu obungaphezulu kwe-99.5%. Olunye uhlobo yintsimbi ye-calcium eveliswa yindlela ye-aluminothermal (ekwabizwa ngokuba yi-slurry method), ngococeko olumalunga nama-97%. Emva kwe-sublimation eyongezelelweyo, ubunyulu bunokuphuculwa ukuya kwinqanaba elithile, kodwa ezinye izinto ezingcolileyo ezifana ne-magnesium kunye ne-aluminium zinomxholo ophezulu kune-electrolytic metal calcium.
Silver white light metal. Ubume obuthambileyo. Ubuninzi be-1.54 g / cm3. Indawo yokunyibilika 839 ± 2 ℃. Indawo yokubilisa 1484 ℃. I-valence edibeneyo+2. Amandla e-ionization yi-6.113 electron volts. Iimpawu zeMichiza ziyasebenza kwaye zinokusabela ngamanzi kunye ne-asidi, zivelisa igesi ye-hydrogen. Umaleko we-oxide kunye nefilimu ye-nitride iya kubumba kumphezulu womoya ukuthintela ukubola okungaphezulu. Xa kushushu, phantse zonke ii-oxide zensimbi zinokuncitshiswa.
Okokuqala, i-metallic calcium ingasetyenziswa njenge-arhente yokunciphisa kwi-metallurgical and chemical industry. Ingasetyenziselwa ukunciphisa i-oxides yesinyithi kunye ne-halides. Ukongeza, i-metallic calcium ingasetyenziselwa ukulungisa ezinye iintsimbi ezinzima ezifunekayo, njenge-zinc, ubhedu kunye nelothe.
Okwesibini, i-metallic calcium nayo idlala indima ebalulekileyo kwimveliso yentsimbi. Icalcium inokongezwa
Ukuphucula ukusebenza kunye nomgangatho wentsimbi. I-calcium inokuphucula amandla kunye nokuqina kwentsimbi, ngelixa iNciphisa i-brittleness yentsimbi. Ukongezelela, ukongeza i-calcium kunokuthintela ukubunjwa kwee-oxides kunye nokungcola kwintsimbi, Ngaloo ndlela kuphuculwe umgangatho wentsimbi.
Ukongeza, i-metallic calcium ingasetyenziselwa ukulungisa ii-alloys ezahlukeneyo. I-calcium inokusebenzisana nezinye izinto zetsimbi Ukuqulunqwa kwe-alloys, njenge-calcium aluminium alloys, i-calcium copper alloys, njl.
Ekugqibeleni, i-metallic calcium ingasetyenziselwa ukulungisa iikhompawundi ezahlukeneyo. Ngokomzekelo, i-calcium inokusebenzisana ne-oxidation Elements ezifana ne-compounds kunye ne-sulfides zenza iikhompawundi ezahlukeneyo, ezifana ne-calcium oxide kunye ne-calcium sulfide. Ezi khompawundi Izinto zisetyenziswa kakhulu ekwenzeni izinto zokwakha, izichumisi, kunye namayeza.
