Pane nzira mbiri dzekugadzira dzesimbi calcium.Imwe ndiyo nzira ye electrolytic, iyo inogadzira metallic calcium nekuchena kazhinji pamusoro pe98.5%.Mushure mekuwedzera sublimation, inogona kusvika pakuchena kweinopfuura 99.5%.Imwe mhando isimbi karusiyamu inogadzirwa nealuminothermal nzira (inozivikanwawo senzira inotsvedza), ine kuchena kunowanzo kutenderedza 97%.Mushure mekuwedzera kuderera, kuchena kunogona kuvandudzwa kune imwe nhanho, asi kumwe kusvibiswa senge magnesium nealuminium zvine zvakakwirira kupfuura electrolytic metal calcium.
Silver white light metal.Soft texture.Density ye1.54 g/cm3.Kunyungudika 839 ± 2 ℃.Boiling point 1484 ℃.Yakasanganiswa valence +2.Ionization simba ndeye 6.113 electron volts.Chemical properties inoshanda uye inogona kuita nemvura uye acid, ichigadzira hydrogen gasi.A layer ye oxide ne nitride film inoumba pamusoro pemhepo kudzivirira imwe corrosion.Kana ichipisa, anenge ese esimbi okisidhi anogona kuderedzwa.
Chekutanga, simbi karusiyamu inogona kushandiswa seanoderedza mumiriri mune simbi uye makemikari maindasitiri.Inogona Kushandiswa kuderedza simbi oxides uye halides.Pamusoro pezvo, metallic calcium inogonawo kushandiswa kugadzira mamwe simbi inorema Inodiwa simbi, senge zingi, mhangura, uye lead.
Chechipiri, metallic calcium inoitawo basa rakakosha mukugadzirwa kwesimbi.Calcium inogona kuwedzerwa
Kuvandudza kushanda uye kunaka kwesimbi.Calcium inogona kuvandudza kusimba uye kusimba kwesimbi, ukuwo Kuderedza brittleness yesimbi.Mukuwedzera, kuwedzera calcium kunogonawo kudzivirira kuumbwa kweoxides uye tsvina musimbi, Nokudaro kuvandudza kunaka kwesimbi.
Mukuwedzera, metallic calcium inogonawo kushandiswa kugadzira zvakasiyana-siyana alloys.Calcium inogona kuwirirana nezvimwe zvinhu zvesimbi Kuumbwa alloys, akadai calcium aruminiyamu alloys, calcium copper alloys, etc. Aya alloys ane zvakawanda zvakakosha zvemuviri uye maitiro ayo emakemikari anogona kushandiswa kugadzira zvinhu zvakasiyana-siyana uye conductive zvinhu.
Pakupedzisira, metallic calcium inogonawo kushandiswa kugadzira akasiyana makomisheni.Semuyenzaniso, karusiyamu inogona kudyidzana neoxidation Zvinhu zvakadai semakomponi uye sulfide zvinoumba makomisheni akasiyana-siyana, akadai se calcium oxide uye calcium sulfide.Mishonga iyi Zvinhu zvinoshandiswa zvakanyanya mukugadzira zvinhu zvekuvakisa, fetereza, nemishonga.
