ʻOihana ʻOihana Huaʻona-Rare Earth

honua laha olehe inoa hui o 17 mau mea metala, i kapa ʻia ʻo "modern industrial vitamin", he kumu waiwai koʻikoʻi koʻikoʻi ma Kina, ua hoʻohana nui ʻia i ka pale aupuni, aerospace, nā mea kūikawā, metallurgy, ikehu a me ka mahiʻai a me nā māla ʻē aʻe he nui.ʻO Kina ka ʻāina nui loa o ka honua a me ka ʻāina hana, nona ke kūlanakauhale ʻo Baotou ma ka ʻāina ʻokoʻa ʻo Inner Mongolia i loaʻa iā 83.7% o nā mālama ʻāina, 37.8% o nā mālama honua, ʻo Bayan Obo mine ka lua honua nui loa o ka honua.

ʻO nā metala honua laha a me kā lākou mau mea hoʻohui i ka hana deoxidation a me ka desulphurization i ka hana kila, hiki ke hōʻemi i ka ʻike o nā mea ʻelua i lalo o 0.001%, hoʻololi i ke ʻano o nā inclusions, hoʻomaʻemaʻe i nā kīʻaha, i mea e hoʻomaikaʻi ai i ka hana ʻana o ke kila, hoʻomaikaʻi i ka ikaika, ʻo ka paʻakikī, ka pale ʻana i ka corrosion a me ke kūpaʻa oxidation.Hoʻohana ʻia nā metala laha ʻole a me kā lākou mau ala i ka hana ʻana i ka hao nodular, ka hao hina hina ikaika a me ka hao vermicular, hiki ke hoʻololi i ke ʻano o ka graphite i ka hao hao, hoʻomaikaʻi i ke kaʻina hana, a hoʻomaikaʻi i nā waiwai mechanical o ka hoʻolei. hao (mea kila, hao hao).

Hoʻohana ʻia ka pauka polishing honua lāʻau e hoʻolalelale i nā mea aniani like ʻole, hoʻohana ʻia ʻo CeO2 e hoʻopau i ke aniani a hoʻomaikaʻi i kona ʻike.Pr6O11, Nd2O3, a pela aku, i hoohana ia no ke kala aniani;Hoʻohana ʻia ʻo La2O3, Nd2O3, CeO2, etc. i ka hana ʻana i ke aniani kūikawā;I ka ʻoihana seramika, hiki ke hoʻohana ʻia nā ʻāina laha ʻole e hana i nā aniani seramika, refractory a me nā mea seramika.Hoʻohana ʻia nā oxides honua maʻemaʻe hoʻokahi e like me Y2O3, Eu2O3, Gd2O3, La2O3, Tb4O7 e synthesize i nā ʻano mea fluorescent, e like me ke kala TV ʻulaʻula phosphor, projection TV white phosphor, ultra short persistence phosphor, nā kukui phosphor, X- ʻO ka phosphor pale i hoʻonui ʻia i ka ray a me nā mea fluorescent hoʻololi māmā.

He ʻāpana koʻikoʻi nā metala honua laha ʻole o nā mea ʻenehana kiʻekiʻe o kēia wā.ʻO kahi pūʻulu o nā mea semiconductor, nā mea electro-optical, nā huila kūikawā, nā mea hana hou a me nā pūhui organometallic i haku ʻia me nā metala honua laha a me nā metala non-ferrous e koi i nā metala honua laha me nā waiwai kūʻokoʻa.He liʻiliʻi ka nui, akā he mea nui.No laila, hoʻohana nui ʻia i ka ʻenehana kamaʻilio o kēia manawa, nā kamepiula uila, ka hoʻomohala ʻana i ka aerospace, ka lāʻau lapaʻau a me ke olakino, nā mea photosensitive, nā mea photoelectric, nā mea ikehu a me nā mea catalyst.He waiwai nui ʻo Kina i nā minerala metala ʻole o ka honua, e hāʻawi ana i nā kūlana waiwai maikaʻi no ka hoʻomohala ʻana i ka ʻoihana metala honua.
