ʻO ka Barium kahi mea kemika me ka hōʻailona Ba a me ka helu atomika 56. ʻO ia ka ʻelima o ka ʻelemu ma ka Pūʻulu 2, he metala lepo ʻeleʻele metala palupalu. Ma muli o kona kiʻekiʻe kiʻekiʻe kemika, ʻaʻole loaʻa ka barium ma ke ʻano he mea manuahi. ʻO kona hydroxide, i ʻike ʻia ma ka mōʻaukala mua o kēia manawa ʻo baryta, ʻaʻole ia he mineral, akā hiki ke hoʻomākaukau ʻia ma ka hoʻomehana ʻana i ka barium carbonate.
Nā noi: Metala a me nā mea hoʻoheheʻe, e halihali ana i nā huila; nā mea hoʻoheheʻe alakaʻi-tin - e hoʻonui i ka pale ʻana i nā kolo; hui pū me ka nickel no nā pahu kukui; mea hoʻohui i ke kila a me ka hao e like me ka inoculant; nā alapili me ka calcium, manganese, silika, a me ka alumini e like me ke kila kila kiʻekiʻe.He liʻiliʻi wale nō nā noi ʻoihana ʻo Barium. Ua hoʻohana mua ʻia ka metala no ka ʻohi ʻana i ka ea i loko o nā paipu māmā. He mea ia o YBCO (high-temperature superconductors) a me electro ceramics, a hoʻohui ʻia i ke kila a me ka hao e hoʻemi i ka nui o nā kalapona kalapona i loko o ka microstructure o ka metala.
Hoʻohana ʻia ʻo Barium, ma ke ʻano he metala a i ʻole i hui ʻia me ka aluminika, e hoʻoneʻe i nā kinoea i makemake ʻole ʻia (guttering) mai nā paipu māmā, e like me nā paipu kiʻi TV. He kūpono ka Barium no kēia kumu no ka haʻahaʻa haʻahaʻa o ke kaomi mahu a me ka reactivity i ka oxygen, nitrogen, carbon dioxide, a me ka wai; hiki iā ia ke wehe i nā kinoea maikaʻi ma ka hoʻoheheʻe ʻana iā lākou i loko o ka lattice kristal. Ke nalo lohi nei kēia noi ma muli o ka piʻi nui ʻana o ka LCD tubeless a me nā hoʻonohonoho plasma.
