He aha ka Thorium Dioxide (ThO2) i hoʻohana ʻia no?
Ua hoʻohana ʻia ʻo Thorium dioxide (thoria) i nā seramika wela kiʻekiʻe, nā lole kinoea, nā wahie nuklea, ka lapalapa ahi, nā kīʻaha, nā aniani optical non-silicia, catalysis, nā filament i nā kukui incandescent, nā cathodes i nā paipu electron a me nā electrodes arc-melting.Nā wahie nukeleaHiki ke hoʻohana ʻia ka Thorium dioxide (thoria) i loko o nā mea hoʻoheheʻe nuklea e like me nā pellet wahie seramika, maʻamau i loko o nā koʻokoʻo wahie nuklea i ʻaʻahu ʻia me nā zirconium alloys. ʻAʻole fissile ʻo Thorium (akā he "momona", hoʻohua i ka fissile uranium-233 ma lalo o ka neutron bombardment);ʻO nā huilaHoʻohana ʻia ʻo Thorium dioxide ma ke ʻano he stabilizer i nā electrodes tungsten i ka hoʻoheheʻe ʻana o TIG, nā paipu electron, a me nā ʻenekini turbine kinoea mokulele.HoʻopalekanaAneane ʻaʻohe waiwai o Thorium dioxide ma ke ʻano he catalyst pāʻoihana, akā ua noiʻi maikaʻi ʻia ia mau noi. He mea hoʻoheheʻe ia i ka synthesis apo nui ʻo Ruzicka.Nā mea hana radiocontrastʻO Thorium dioxide ka mea hana mua ma Thorotrast, he mea hoʻohana radiocontrast maʻamau i hoʻohana ʻia no ka angiography cerebral, akā naʻe, ke kumu ia i ke ʻano o ka maʻi kanesa (hepatic angiosarcoma) i nā makahiki he nui ma hope o ka lawelawe ʻana.Hana anianiKe hoʻohui ʻia i ke aniani, kōkua ka thorium dioxide i ka hoʻonui ʻana i kāna ʻōlelo kuhikuhi refractive a hoʻemi i ka hoʻopuehu. Loaʻa ia aniani i ka noi i nā lens kiʻekiʻe no nā kāmera a me nā mea hana ʻepekema.
