He aha ka mea e hoʻohana ʻia ai ka Thorium Dioxide (ThO2)?
Ua hoʻohana ʻia ka Thorium dioxide (thoria) i loko o nā keramika wela kiʻekiʻe, nā mantle kinoea, ka wahie nukelea, ka pīpī lapalapa, nā ipu hoʻoheheʻe, ke aniani optical non-silicia, catalysis, nā filaments i loko o nā kukui incandescent, nā cathodes i loko o nā paipu electron a me nā electrodes arc-melting.Nā wahie nukeleaHiki ke hoʻohana ʻia ka Thorium dioxide (thoria) i loko o nā mea hana nukelea e like me nā pellets wahie keramika, i loaʻa pinepine ʻia i loko o nā koʻokoʻo wahie nukelea i uhi ʻia me nā zirconium alloys. ʻAʻole fissile ʻo Thorium (akā "momona", e hoʻoulu ana i ka uranium fissile-233 ma lalo o ka neutron bombardment);Nā mea hoʻohuihuiHoʻohana ʻia ka Thorium dioxide ma ke ʻano he mea hoʻopaʻa i nā electrodes tungsten i ka hoʻopili ʻana o TIG, nā paipu electron, a me nā ʻenekini turbine kinoea mokulele.HoʻouluuluʻAneʻane ʻaʻohe waiwai o ka Thorium dioxide ma ke ʻano he mea hoʻouluulu kalepa, akā ua noiʻi maikaʻi ʻia kēlā mau noi. He mea hoʻouluulu ia i ka hana apo nui ʻo Ruzicka.Nā mea hana hoʻohālikelike lekiōʻO Thorium dioxide ka mea nui i loko o Thorotrast, kahi mea radiocontrast maʻamau i hoʻohana ʻia no ka angiography cerebral, akā naʻe, ke kumu nei ia i kahi ʻano maʻi kanesa kakaikahi (hepatic angiosarcoma) i nā makahiki he nui ma hope o ka hoʻokele ʻana.Hana anianiKe hoʻohui ʻia i ke aniani, kōkua ka thorium dioxide i ka hoʻonui ʻana i kāna refractive index a hoʻemi i ka dispersion. Loaʻa ka hoʻohana ʻana i kēlā aniani i nā aniani kiʻekiʻe no nā kāmela a me nā mea hana ʻepekema.
