Kunezindlela ezimbili zokukhiqiza ze-metallic calcium. Enye indlela ye-electrolytic, ekhiqiza i-metallic calcium ngobumsulwa ngokuvamile obungaphezu kwama-98.5%. Ngemuva kokwehliswa okwengeziwe, ingafinyelela ubumsulwa obungaphezu kwama-99.5%. Olunye uhlobo i-calcium yensimbi ekhiqizwa indlela ye-aluminothermal (eyaziwa nangokuthi indlela ye-slurry), enobumsulwa obucishe bube ngu-97%. Ngemuva kokuphinda kuncishiswe, ubumsulwa bungathuthukiswa ngokwezinga elithile, kodwa okunye ukungcola okufana ne-magnesium ne-aluminium kunokuqukethwe okuphezulu kune-electrolytic metal calcium.
Insimbi ekhanyayo emhlophe esiliva. Ukuthungwa okuthambile. Ukuminyana okungu-1.54 g/cm3. Iphoyinti lokuncibilika 839 ± 2 ℃. Iphoyinti lokubilisa 1484 ℃. I-valence+2 ehlanganisiwe. Amandla e-ionization angu-6.113 electron volts. Izici zamakhemikhali ziyasebenza futhi zingasabela ngamanzi ne-asidi, zikhiqize igesi ye-hydrogen. Ungqimba lwefilimu ye-oxide ne-nitride luzokwakheka ebusweni bomoya ukuvimbela ukugqwala okuqhubekayo. Lapho kushisa, cishe wonke ama-oxide ensimbi angancishiswa.
Okokuqala, i-metallic calcium ingasetshenziswa njenge-ejenti yokunciphisa izimboni ze-metallurgical kanye namakhemikhali. Ingasetshenziselwa ukunciphisa ama-oxide ensimbi nama-halides. Ngaphezu kwalokho, i-metallic calcium ingasetshenziswa futhi ukulungisa ezinye izinsimbi ezisindayo Izinsimbi ezidingekayo, njenge-zinc, ithusi, nomthofu.
Okwesibili, i-metallic calcium nayo idlala indima ebalulekile ekukhiqizeni insimbi. I-calcium ingezwa
Ukuthuthukisa ukusebenza kanye nekhwalithi yensimbi. I-calcium ingathuthukisa amandla nokuqina kwensimbi, kuyilapho Yehlisa ukushwabana kwensimbi. Ngaphezu kwalokho, ukwengeza i-calcium kungavimbela ukwakheka kwama-oxide nokungcola ensimbi, ngaleyo ndlela kuthuthukise izinga lensimbi.
Ngaphezu kwalokho, i-metallic calcium ingasetshenziswa futhi ukulungisa ama-alloys ahlukahlukene. I-calcium ingakwazi ukusebenzisana nezinye izakhi zensimbi Ama-alloys okubunjwa, njengama-alloys e-calcium aluminium, ama-alloys ethusi e-calcium, njll. Lawa ma-alloys anezakhiwo eziningi ezikhethekile ezibonakalayo Futhi izakhiwo zawo zamakhemikhali zingasetshenziswa ukwenza izinto ezihlukahlukene kanye nezinto eziqhutshwayo.
Ekugcineni, i-metallic calcium ingasetshenziswa futhi ukulungisa izinhlanganisela ezihlukahlukene. Isibonelo, i-calcium ingasebenzisana ne-oxidation Izinto ezifana nezinhlanganisela nama-sulfide zakha inhlanganisela ehlukahlukene, njenge-calcium oxide ne-calcium sulfide. Lezi zinhlanganisela Izinto zisetshenziswa kakhulu ekwenzeni izinto zokwakha, umanyolo, kanye nemithi.
