TŠEPE KHALE

Ho na le mekhoa e 'meli ea tlhahiso ea tšepe ea calcium.E 'ngoe ke mokhoa oa electrolytic, o hlahisang calcium ea tšepe e nang le bohloeki ka kakaretso ka holimo ho 98.5%.Kamora ho fokotseha ho eketsehileng, e ka fihla bohloeki bo fetang 99.5%.Mofuta o mong ke tšepe calcium e hlahisoang ke mokhoa oa aluminothermal (o tsejoang hape e le mokhoa oa slurry), ka bohloeki ba ka kakaretso ho pota 97%.Ka mor'a ho fokotseha ho eketsehileng, bohloeki bo ka ntlafatsoa ho isa bohōleng bo itseng, empa litšila tse ling tse kang magnesium le aluminium li na le litaba tse phahameng ho feta electrolytic metal calcium.

Silver white light light.Sebopeho se bonolo.Boima ba 1.54 g/cm3.Sebaka se qhibilihang ke 839 ± 2 ℃.Sebaka se belang 1484 ℃.Valence +2 e kopantsoeng.Matla a ionization ke 6.113 electron volts.Lintho tsa lik'hemik'hale li sebetsa 'me li ka itšoara ka metsi le asiti, li hlahisa khase ea hydrogen.Lera la oxide le filimi ea nitride li tla theha holim'a moea ho thibela kutu e eketsehileng.Ha ho chesa, hoo e ka bang li-oxide tsohle tsa tšepe li ka fokotsoa.

Taba ea pele, tšepe ea calcium e ka sebelisoa e le ntho e fokotsang indastering ea metallurgic le ea lik'hemik'hale.E ka sebelisoa ho fokotsa li-oxide tsa tšepe le halides.Ho feta moo, metallic calcium e ka boela ea sebelisoa ho lokisa litšepe tse ling tse boima Litšepe tse Hlokehang, tse kang zinki, koporo le loto.

Taba ea bobeli, metallic calcium e boetse e phetha karolo ea bohlokoa tlhahisong ea tšepe.Calcium e ka eketsoa
Ho ntlafatsa ts'ebetso le boleng ba tšepe.Calcium e ka ntlafatsa matla le ho tiea ha tšepe, ha e ntse e Fokotsa ho senyeha ha tšepe.Ho phaella moo, ho eketsa khalsiamo ho ka boela ha thibela ho thehoa ha li-oxide le litšila ka tšepe, kahoo ho ntlafatsa boleng ba tšepe.

Ntle le moo, calcium calcium e ka sebelisoa ho lokisa li-alloys tse fapaneng.Calcium e ka sebelisana le lisebelisoa tse ling tsa tšepe Li-alloys tsa ho etsa li-alloys, tse kang li-alloys tsa calcium aluminium, li-alloys tsa koporo tsa calcium, joalo-joalo Li-alloys tsena li na le lintho tse ngata tse khethehileng tsa 'mele Le lik'hemik'hale tsa eona tsa lik'hemik'hale li ka sebelisoa ho etsa lisebelisoa tse sa tšoaneng le lisebelisoa tsa conductive.

Qetellong, tšepe ea calcium e ka boela ea sebelisoa ho lokisa metsoako e fapaneng.Mohlala, khalsiamo e ka sebelisana le oxidation Lintho tse kang metsoako le sulfide li etsa metsoako e fapaneng, joalo ka calcium oxide le calcium sulfide.Metsoako ena Lintho li sebelisoa haholo ha ho etsoa thepa ea moaho, manyolo, le meriana.
