ʻO Beryllium oxide ceramics me ke kiʻekiʻe thermal conductivity a me nā hiʻohiʻona pohō haʻahaʻa

Hoʻohana ʻia nā ceramics BeO i ka hana kiʻekiʻe, nā pūʻolo microwave mana kiʻekiʻe, nā pūʻolo transistor uila uila kiʻekiʻe, a me nā ʻāpana multi-chip kaapuni kiʻekiʻe. Hiki i ka hoʻohana ʻana i nā mea BeO ke hoʻopau i ka wela i hana ʻia i ka ʻōnaehana i ka manawa e hōʻoia i ka paʻa a me ka hilinaʻi o ka ʻōnaehana.

'Ōlelo Aʻo: ʻO Transistor kahi mea semiconductor paʻa, me ka ʻike, hoʻoponopono, hoʻonui, hoʻololi, hoʻoponopono uila, hoʻololi i ka hōʻailona a me nā hana ʻē aʻe. Ma ke ʻano he ʻano hoʻololi o kēia manawa, hiki i ka transistor ke hoʻomalu i ka hopena o kēia manawa ma muli o ka volta komo. ʻAʻole like me nā hoʻololi mechanical maʻamau, hoʻohana nā transistors i ke kelepona no ka mālama ʻana i kā lākou wehe a pani ʻana, a hiki ke wikiwiki loa ka wikiwiki o ka hoʻololi ʻana, a hiki i ka wikiwiki o ka hoʻololi ʻana i loko o ka hale hana ke piʻi aku ma mua o 100GHz.

ʻO ka nuklear reactor ceramic material kekahi o nā mea nui i hoʻohana ʻia i nā reactors, i nā reactors a me nā fusion reactors, loaʻa nā mea seramika i nā mea ikaika kiʻekiʻe a me ka radiation gamma, no laila, i ka hoʻohui ʻana i ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa corrosion, pono nā mea seramika e loaʻa ka maikaʻi. paʻa paʻa. ʻO nā mea hoʻohālikelike neutron a me nā mea hoʻoponopono (moderators) o ka wahie nukle he mau BeO, B4C a i ʻole nā ​​mea graphite.

ʻOi aku ka maikaʻi o ka paʻa ʻana o ka irradiation o ka Beryllium oxide ma mua o ka metala, ʻoi aku ka nui o ka nui ma mua o ka metala beryllium, ʻoi aku ka ikaika ma ka wela kiʻekiʻe, ʻoi aku ka maikaʻi o ka conductivity thermal, a ʻoi aku ka liʻiliʻi ma mua o ka metala beryllium. He kūpono no ka hoʻohana ʻana ma ke ʻano he reflector, moderator a me ka dispersion phase combustion collective i loko o kahi reactor. Hiki ke hoʻohana ʻia ka Beryllium oxide e like me ke koʻokoʻo hoʻokele i nā reactors nuklea, a hiki ke hoʻohui ʻia me nā ceramics U2O e lilo i wahie nuklea.
