I kēlā me kēia manawa a mākou e kamaʻilio ai e pili ana i ka beryllium oxide, ʻo ka pane mua, he mea ʻawahia ia inā no nā amateurs a i ʻole nā mea akamai. ʻOiai he mea ʻawahia ka beryllium oxide, ʻaʻole ʻawahia nā keramika beryllium oxide.
Hoʻohana nui ʻia ka Beryllium oxide ma nā kahua o ka metallurgy kūikawā, ʻenehana uila vacuum, ʻenehana nukelea, microelectronics a me ka ʻenehana photoelectron ma muli o kona conductivity thermal kiʻekiʻe, insulation kiʻekiʻe, dielectric constant haʻahaʻa, pohō haʻahaʻa haʻahaʻa, a me ka hoʻololi maikaʻi ʻana i ke kaʻina hana.
Nā mea uila mana kiʻekiʻe a me nā kaapuni i hoʻohui ʻia
I ka wā ma mua, ua kālele nui ʻia ka noiʻi a me ka hoʻomohala ʻana o nā mea uila i ka hoʻolālā hana a me ka hoʻolālā mīkini, akā i kēia manawa ua uku nui ʻia ka nānā ʻana i ka hoʻolālā wela, a ʻaʻole i hoʻoponopono maikaʻi ʻia nā pilikia loea o ka nalowale wela o nā mea mana kiʻekiʻe he nui. ʻO ka beryllium oxide (BeO) kahi mea keramika me ka conductivity kiʻekiʻe a me ka dielectric constant haʻahaʻa, ka mea e hoʻohana nui ʻia ai i ke kahua o ka ʻenehana uila.
I kēia manawa, ua hoʻohana ʻia nā keramika BeO i loko o ka hoʻopili microwave mana kiʻekiʻe, ka hoʻopili transistor uila alapine kiʻekiʻe, a me nā ʻāpana multichip density circuit kiʻekiʻe, a hiki ke hoʻopau ʻia ka wela i hana ʻia i loko o ka ʻōnaehana i ka manawa kūpono ma ka hoʻohana ʻana i nā mea BeO e hōʻoia i ke kūpaʻa a me ka hilinaʻi o ka ʻōnaehana.
Mea hana nukelea
ʻO ka mea seramika kekahi o nā mea nui loa i hoʻohana ʻia i loko o ka reactor nukelea. I loko o nā reactors a me nā mea hoʻololi, loaʻa i nā mea seramika ka radiation mai nā ʻāpana ikehu kiʻekiʻe a me nā kukuna beta. No laila, me ka pale ʻana i ka mahana kiʻekiʻe a me ka palaho, pono pū nā mea seramika i ke kūpaʻa ʻoi aku ka maikaʻi o ke kūkulu ʻana. ʻO ka neutron reflection a me ka moderator o ka wahie nukelea i hana pinepine ʻia me BeO, B4C a i ʻole graphite.
ʻOi aku ka maikaʻi o ke kūpaʻa o ka beryllium oxide i ka mahana kiʻekiʻe ma mua o ka metala; ʻoi aku ke kiʻekiʻe o ka density ma mua o ka beryllium metal; ʻoi aku ka maikaʻi o ka ikaika ma lalo o ke kiʻekiʻe o ka mahana; kiʻekiʻe ke alakaʻi wela a ʻoi aku ka haʻahaʻa o ke kumukūʻai ma mua o ka beryllium metal. ʻO kēia mau waiwai maikaʻi a pau e kūpono ai no ka hoʻohana ʻana ma ke ʻano he reflector, moderator, a me kahi hui puhi ʻāpana i hoʻopuehu ʻia i loko o nā reactors. Hiki ke hoʻohana ʻia ka beryllium oxide ma ke ʻano he koʻokoʻo hoʻomalu i loko o nā reactors nukelea, a hiki ke hoʻohana ʻia me ka hui pū ʻana me nā keramika U2O ma ke ʻano he wahie nukelea.
ipu hoʻoheheʻe kūikawā
ʻOiaʻiʻo, he mea paʻa ʻole nā keramika BeO. Eia kekahi, hiki ke hoʻohana ʻia ka ipu hoʻoheheʻe keramika BeO i ka hoʻoheheʻe ʻana i nā metala kakaikahi a me nā metala makamae, ʻoi aku hoʻi i ka metala maʻemaʻe kiʻekiʻe a i ʻole ka hui hao, a ʻo ka mahana hana o ka ipu hoʻoheheʻe a hiki i ka 2000 ℃. Ma muli o ko lākou mahana hoʻoheheʻe kiʻekiʻe (2550 ℃) a me ke kūpaʻa kemika kiʻekiʻe (alkali), ke kūpaʻa wela a me ka maʻemaʻe, hiki ke hoʻohana ʻia nā keramika BeO no ka glaze hoʻoheheʻe ʻia a me ka plutonium.
Nā noi ʻē aʻe
Loaʻa i nā keramika beryllium oxide ka conductivity thermal maikaʻi, ʻo ia hoʻi ʻelua mau kauoha o ka nui ma mua o ka quartz maʻamau, no laila he kiʻekiʻe ka pono o ka laser a me ka mana hoʻopuka kiʻekiʻe.
Hiki ke hoʻohui ʻia nā keramika BeO ma ke ʻano he ʻāpana i nā ʻāpana like ʻole o ke aniani. Hoʻohana ʻia ke aniani i loaʻa ka beryllium oxide, hiki ke hele ma o nā kukuna-x, e hana i nā ʻōmole kukuna-X hiki ke hoʻohana ʻia no ka nānā ʻana i ke ʻano a me ke ʻano lapaʻau e mālama i nā maʻi ʻili.
He ʻokoʻa nā keramika beryllium oxide mai nā keramika uila ʻē aʻe. A hiki i kēia manawa, ʻo kona conductivity thermal kiʻekiʻe a me nā ʻano pohō haʻahaʻa he mea paʻakikī ke pani ʻia e nā mea ʻē aʻe. Ma muli o ke koi nui ma nā kahua ʻepekema a me nā ʻenehana he nui, a me ka ʻawahia o ka beryllium oxide, ua paʻakikī loa nā hana pale, a he kakaikahi nā hale hana ma ka honua e hiki ke hana palekana i nā keramika beryllium oxide.
Kumuwaiwai Hoʻolako no ka Beryllium Oxide Powder
Ma ke ʻano he mea hana a me ka mea hoʻolako Kina ʻoihana, ua loea ʻo UrbanMines Tech Limited i ka Beryllium Oxide Powder a hiki ke hana maʻamau i ka papa maʻemaʻe e like me 99.0%, 99.5%, 99.8% a me 99.9%. Aia kahi waihona wahi no ka papa 99.0% a loaʻa no ka laʻana.
