KALSIUM METAL

ʻElua mau ala hana no ka calcium metala.ʻO kekahi ke ʻano electrolytic, e hoʻopuka ana i ka calcium metala me ka maʻemaʻe ma mua o 98.5%.Ma hope o ka sublimation hou aʻe, hiki ke hōʻea i kahi maʻemaʻe ma luna o 99.5%.ʻO kekahi ʻano he calcium metala i hana ʻia e ke ʻano aluminothermal (ʻike ʻia ʻo ke ʻano slurry), me ka maʻemaʻe ma kahi o 97%.Ma hope o ka sublimation hou, hiki ke hoʻomaikaʻi ʻia ka maʻemaʻe i kekahi ʻano, akā ʻoi aku ka nui o nā mea haumia e like me ka magnesium a me ka alumini ma mua o ka calcium metala electrolytic.

Metala māmā keʻokeʻo kala.ʻAno palupalu.ʻO ka mānoanoa o 1.54 g/cm3.Ka helu hehee 839 ± 2 ℃.Ka helu hoʻolapalapa 1484 ℃.Huina valence+2.ʻO ka ikehu Ionization he 6.113 electron volts.ʻO nā waiwai kemika a hiki ke hana me ka wai a me ka waikawa, e hana ana i ke kinoea hydrogen.E hoʻokumu ʻia kahi ʻāpana o ka oxide a me ka nitride kiʻiʻoniʻoni ma luna o ka ʻili o ka lewa no ka pale ʻana i ka pala.Ke hoʻomehana ʻia, aneane hiki ke hoʻemi ʻia nā ʻokikene metala āpau.

ʻO ka mea mua, hiki ke hoʻohana ʻia ka calcium metala ma ke ʻano he mea hōʻemi i ka ʻoihana metallurgical a me nā kemika.Hiki ke hoʻohana ʻia e hōʻemi i nā oxide metala a me nā halides.Eia hou, hiki ke hoʻohana ʻia ka calcium metala no ka hoʻomākaukau ʻana i nā metala kaumaha ʻē aʻe.

ʻO ka lua, he mea koʻikoʻi ka calcium metala i ka hana kila.Hiki ke hoʻohui ʻia ka calcium
E hoʻomaikaʻi i ka hana a me ka maikaʻi o ke kila.Hiki i ka calcium ke hoʻomaikaʻi i ka ikaika a me ka paʻakikī o ke kila, ʻoiai e hoʻemi i ka brittleness o ke kila.Eia kekahi, hiki i ka hoʻohui ʻana i ka calcium ke pale i ka hoʻokumu ʻana o nā oxides a me nā haumia i ke kila, pēlā e hoʻomaikaʻi ai i ka maikaʻi o ke kila.

Eia kekahi, hiki ke hoʻohana ʻia ka calcium metala no ka hoʻomākaukau ʻana i nā ʻāpana like ʻole.Hiki i ka calcium ke launa pū me nā mea metala ʻē aʻe.

ʻO ka hope, hiki ke hoʻohana ʻia ka calcium metala no ka hoʻomākaukau ʻana i nā pūhui like ʻole.No ka laʻana, hiki i ka calcium ke launa pū me ka oxidation ʻO nā mea e like me nā pūhui a me nā sulfides e hana i nā pūhui like ʻole, e like me ka calcium oxide a me ka calcium sulfide.Hoʻohana nui ʻia kēia mau mea i ka hana ʻana i nā mea kūkulu hale, nā mea kanu, a me nā lāʻau lapaʻau.
