Wahi a ka Research Report e pili ana i ka noiʻi a me ka hoʻopukapuka kālā o ka ʻoihana alumina maʻemaʻe kiʻekiʻe o Kina (2021 Edition) i hoʻokuʻu ʻia e Limu ʻike kūkākūkā, ʻo ka alumina maʻemaʻe kiʻekiʻe ka pono o ka paʻakikī kiʻekiʻe, ka ikaika kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe, a hoʻohana nui ʻia i ka uila. semiconductor a me nā ʻoihana ʻē aʻe.Hoʻohana nui ʻia ka alumina hoʻomaʻemaʻe kiʻekiʻe e hana i nā substrates seramika no nā kaapuni i hoʻohui ʻia a me nā sensor automotive.ʻO ia kekahi o nā mea i hoʻohana nui ʻia.
Ma Kina, ʻo ka mana nominal o nā ʻoihana kūloko e hana ana i ka alumina maʻemaʻe kiʻekiʻe ma ke kauoha o nā tausani o nā tona.ʻO ka ʻoiaʻiʻo, ʻo ka hapa nui o lākou i hoʻopaʻa ʻia i nā mākeke haʻahaʻa e like me ka phosphors.Eia nō naʻe, ua piʻi ka maʻemaʻe o kekahi mau ʻoihana kūloko ma luna o 4n5, a ʻaʻohe ʻokoʻa me nā ʻoihana alakaʻi haole e pili ana i ka maʻemaʻe.Hiki i ka noi i ke kuhikuhi o ka substrate sapphire ke hoʻomaopopo i ka hoʻokomo ʻana i ka hoʻololi.Eia nō naʻe, ma ke ʻano o ka nui o nā ʻāpana, hiki i nā ʻoihana ʻē aʻe ke hoʻokō ma lalo o 30nm (nm), a ʻo ka hapa nui o nā ʻoihana kūloko e loaʻa i kahi āpau.No laila, i kēia manawa, hāʻawi nui ʻia ka alumina no ka lithium battery diaphragm e Sumitomo chemical a me nā mea hana ʻē aʻe.
Ma ke kahua noi sapphire, ʻike ʻia nā ʻoihana hana alumina hoʻomaʻemaʻe kiʻekiʻe o ka home a kokoke i nā mea kūʻai aku ma ka ʻāina, he mau mea maikaʻi loa ia.I ka manawa like, ma ke kula o ka alumina maʻemaʻe kiʻekiʻe kiʻekiʻe, me ka holomua mau o ka ʻenehana ʻoihana kūloko, ʻo nā ʻoihana kūloko me ka ʻenehana alakaʻi a me ka hana kiʻekiʻe e ʻike koke i ka hoʻokomo ʻana mai, A komo i ka mākeke honua e hoʻokuʻu kiʻekiʻe. - alumina maemae.
Ma muli o ka monopoly o nā mea hoʻokomo kiʻekiʻe a me ka saturation o nā haʻahaʻa haʻahaʻa i ka mākeke alumina maʻemaʻe kiʻekiʻe o ka home, e lilo ia i mea hoʻomohala no ka alumina maʻemaʻe kiʻekiʻe e pani i nā lawe mai a hoʻokō i ka koi o ka mākeke kūloko.
ʻO ka hoʻomohala ʻana o ka ʻoihana alumina maʻemaʻe kiʻekiʻe ma Kina ua lohi a aia nō i kona wā kamaliʻi.I kēia manawa, hoʻomaikaʻi ʻia ke kaʻina hana nui i ka kaʻina Bayer.I kēia manawa, ʻo nā huahana kūloko ka nui o 4N alumina, a he liʻiliʻi nā ʻoihana kūloko e hiki ke hana i nā huahana 5N.I ka makahiki 2019, he 7600 tons ka puka o ka ʻoihana alumina kiʻekiʻe-maʻemaʻe o Kina, he 15700 tons ke koi, a ua hōʻea ka ʻupena i 8100 tons.I ka makahiki 2020, ʻo 8280 tons ka puka o ka ʻoihana alumina kiʻekiʻe o Kina, ʻo 17035 tons ke koi, a ua hōʻea ka ʻupena i 8750 tons.
ʻO Shandong Zhanchi New Material Co., Ltd (Shanghai Chenxu Trading Co., Ltd) i hana i ka 5N 99.999 alumina maʻemaʻe kiʻekiʻe, hoʻopiha ia i ke āpau o ka ʻenehana kūloko a wāwahi i ka monopoly o ka ʻenehana haole.
