Strontium carbonate
ʻO ka strontium carbonate kahi mea waiwai waiwai nui me ka nui o ka hoʻohana ʻana.He mineral carbonate ia, no ka hui aragonite, he mea maʻamau a loaʻa i ka limestone a i ʻole marlstone ma ke ʻano o nā veins.Ma ke ʻano, aia ka hapa nui ma ke ʻano o ka mineral rhodochrosite a me ka strontite, e noho pū ana me ka barium carbonate, barite, calcite, celestite, fluorite a me ka sulfide, ʻala ʻole a ʻono ʻole, ʻo ka hapa nui keʻokeʻo keʻokeʻo a i ʻole colorless rhombic crystal, a i ʻole hina, melemele-keʻokeʻo, ʻōmaʻomaʻo a ʻeleʻele paha ke loaʻa i ka haumia.ʻO ka strontium carbonate crystal he ʻano nila, a ʻo kona hui ʻana he ʻano granular, columnar, a me nā nila radioactive.ʻAʻole waihoʻoluʻu kona hiʻohiʻona, keʻokeʻo, ʻōmaʻomaʻo-melemele, me ka ʻulaʻula a hiki i ka translucent aniani luster, fracture oil luster, brittle, a nāwaliwali nā kukui uliuli māmā ma lalo o ke kukui cathode.Paʻa ka strontium carbonate, hiki ʻole ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe iki ʻia i ka ammonia, ammonium carbonate a me carbon dioxide saturated aqueous solution, a hiki ʻole ke hoʻoheheʻe ʻia i ka waiʻona.Eia kekahi, ʻo ka strontium carbonate kekahi mea waiwai nui no ka celestite, kahi kumu mineral laʻa.I kēia manawa, ʻaneʻane pau ka celestite kiʻekiʻe.
Me ka hoʻomau mau ʻana o ka ʻoihana honua, ua hoʻonui ʻia ke kahua noi o strontium.Mai ke kenekulia 19 a hiki i ka hoʻomaka ʻana o kēia kenekulia, hoʻohana nā kānaka i ka strontium hydroxide e hana i ke kō a hoʻomaʻemaʻe i ka syrup beet;I loko o nā kaua honua ʻelua, ua hoʻohana nui ʻia nā pūhui strontium i ka hana ʻana i nā mea ahi a me nā pōkā hōʻailona;I nā makahiki 1920 a me 1930, ua hoʻohana ʻia ka strontium carbonate ma ke ʻano he desulfurizer no ka hana kila e wehe i ka sulfur, phosphorus a me nā mea ʻino ʻē aʻe;I ka makahiki 1950, ua hoʻohana ʻia ka strontium carbonate e hoʻomaʻemaʻe i ka zinc i ka hana ʻana i ka zinc electrolytic, me ka maʻemaʻe o 99.99%;I ka hopena o nā makahiki 1960, ua hoʻohana nui ʻia ka strontium carbonate ma ke ʻano he mea magnetic;Hoʻohana ʻia ʻo Strontium titanate e like me ka hoʻomanaʻo kamepiula, a hoʻohana ʻia ka strontium chloride i wahie rocket;I ka makahiki 1968, ua hoʻohana ʻia ka strontium carbonate i ke aniani aniani kīwī no ka mea ua ʻike ʻia e hoʻohana ʻia no ka hana pale X-ray maikaʻi.I kēia manawa ke ulu wikiwiki nei ka noi a ua lilo i hoʻokahi o nā kahua noi nui o strontium;Ke hoʻonui nei hoʻi ʻo Strontium i kāna ʻano noi ma nā kahua ʻē aʻe.Mai ia manawa mai, ua loa'a ka mana'o nui a me ka nānā 'ana i ka strontium carbonate a me nā pūhui strontium 'ē a'e (strontium salts).
Ma ke ʻano he mea waiwai nui ʻoihana, strontium carbonatehoʻohana nui ʻia i ka hana ʻana i nā paipu kiʻi, nā mea nānā, nā mea nānā ʻoihana, nā mea uila, etc.I ka manawa like, ʻo ka strontium carbonate ka mea nui no ka hoʻomākaukau ʻana i ka strontium metala a me nā paʻakai strontium like ʻole.Eia kekahi, hiki ke hoʻohana ʻia ka strontium carbonate i ka hana ʻana i ke ahi, ke aniani fluorescent, nā pōkā hōʻailona, ka hana pepa, ka lāʻau lapaʻau, nā reagents analytical, ka hoʻomaʻemaʻe kō, ka zinc metala electrolyte hoʻomaʻemaʻe, strontium salt pigment manufacturing, etc. -maemae strontium carbonate, e like me ka nui-pale waihoʻoluʻu TV set, waihoʻoluʻu hōʻike no nā kamepiula a me kiʻekiʻe-performance magnetic mea, a pela aku. i ka pau ʻana o nā veins mineral, ke piʻi aʻe o nā kumukūʻai ikehu a me ka haumia o ke kaiapuni.I kēia manawa, hiki ke ʻike ʻia ka mākeke noi o strontium carbonate.
I kēia manawa, e hoʻolauna mākou i ka noi kikoʻī o ka strontium carbonate:
ʻO ka mea mua, ua hoʻokaʻawale ʻia ka strontium carbonate i nā kikoʻī granular a me ka pauka.Hoʻohana nui ʻia ka granular i ke aniani TV ma Kina, a ua hoʻohana nui ʻia ka pauka i ka hana ʻana i nā mea magnetic strontium ferrite, nonferrous metal smelting, ʻulaʻula pyrotechnic heartliver a me ka hana ʻana o ka strontium carbonate kiʻekiʻe no nā mea uila holomua e like me PTC, Hoʻohana nui ʻia i ka hana ʻana i ke aniani TV a me ke aniani hōʻike, strontium ferrite, nā mea magnetic a me ka desulfurization metala nonferrous, a hoʻohana pū ʻia i ka hana ʻana i nā mea ahi, aniani fluorescent, Signal bomb, pepa hana, lāʻau lapaʻau, analytical reagent a me nā mea maka no ka hana ʻana i nā mea ʻē aʻe. nā paʻakai strontium.
ʻO nā hoʻohana nui o ka strontium carbonate i nā noi uila:
Hoʻohana ʻia no ka hana ʻana i ke kelepona kala kala (CTV) e hoʻomoʻa i nā electrons i hana ʻia e ka cathode
1.Manufacture o strontium ferrite no ka mau mea hoʻohana i hoʻohana 'ia i loko o ka leo leo a me ka puka magnets.
2.Production o cathode ray paipu no ka kala TV
3.Also hoʻohana no ka electromagnets a me ka strontium ferrite
4. Hiki ke hana ʻia i nā kaʻa liʻiliʻi, nā mea hoʻokaʻawale magnetic a me nā leo kani
5. Absorb X-rays
6. Hoʻohana ʻia ia no ka hana ʻana i kekahi mau superconductors, e like me BSCCO, a no nā mea electroluminescent pū kekahi.ʻO ka mua, ua hoʻopaʻa ʻia i loko o SrO, a laila hui pū ʻia me ka sulfur e lilo i SrS: x, kahi maʻamau ʻo x ka europium.
I ka ʻoihana seramika, hoʻokani ka strontium carbonate i kēia ʻano hana:
1. Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻohui o ka glaze.
2. It hana e like me ka flux
3. E hoʻololi i ke kala o kekahi metala oxides.
ʻae nō hoʻi,ʻO ka hoʻohana maʻamau o ka strontium carbonate ma ke ʻano he kala maʻalahi i nā mea ahi.
I ka pōkole, hoʻohana nui ʻia ka strontium carbonate, ka mea nui i ka hana ʻana i ke aniani TV a me ke aniani hōʻike, strontium ferrite, nā mea magnetic a me ka desulfurization metala nonferrous a me nā ʻoihana ʻē aʻe, a i ʻole i ka hana ʻana i nā mea ahi, aniani fluorescent, hōʻailona pōkā, hana pepa, lāʻau lapaʻau. , nā mea hoʻopalekana analytical a me nā mea maka no ka hana ʻana i nā paʻakai strontium ʻē aʻe.
Wahi a nā helu, ʻoi aku ʻo Kina ma mua o 20 mau ʻoihana e hana ana i ka strontium carbonate production, me ka nui o ka makahiki o 289000 tons, lilo i mea hana nui loa a me ka mea kūʻai aku i nā gills carbonated, a lawe aku i nā wahi āpau o ka honua, e hauʻoli ana i ka inoa kiʻekiʻe. ma ka mākeke honua.Wahi a nā helu kuʻuna, ʻo ka lawe ʻana aku o Kina i ka strontium carbonate i nā makahiki i hala iho nei he 78700 tons i ka makahiki 2003, 98000 tons i 2004 a me 33000 tons i 2005, helu no 34.25%, 36.8% a me 39.5.7% o ka huina o ka ʻāina. ʻO 54.7% a me 57.8% o ke kālepa mākeke honua.ʻO Celestite, ka mea waiwai nui o ka strontium carbonate, he mineral liʻiliʻi ma ka honua a he kumu waiwai mineral laha ʻole hiki ke hoʻololi ʻia.
E like me kā mākou e ʻike ai, ʻo ka strontium kahi waiwai koʻikoʻi koʻikoʻi me ka nui o ka hoʻohana ʻana.ʻO kekahi o kāna hoʻohana ʻana, ʻo ia ka hana ʻana i nā paʻakai strontium, e like me ka strontium carbonate, strontium titanate, nitrate, strontium oxide, strontium chloride, strontium chromate, strontium ferrite, a pēlā aku.
Ma Kina, loaʻa i kā mākou strontium carbonate kekahi pono i ka ʻōlelo o ka lako a me ka hana.Hiki ke ʻōlelo ʻia he manaʻo maikaʻi ka mākeke o ka strontium carbonate.
