Meatotino Faaletino ma Vailaau	mea e leai ni lanu tioata orthorhombic po'o le pa'epa'e foliga pa'epa'e. mea liusuavai 1580 ℃ va'aiga va'aiga 4.50(15 ℃) solubility e toetoe lava a le mafai ona solu i le vai, ethanol ma acid. Solu i le sulfuric acid vevela. tioata orthorhombic e leai ni lanu po o le pa'epa'e amorphous pa'epa'e. Tulaga va'aiga 4.50 (15 tikeri C). Liu liusuavai 1580 °c. Ole suiga ole Polycrystalline e tupu ile 1150 °c. Na amata le pala tele ile tusa ole 1400°c. Mautu o vailaau. Fa'ata'ita'i e le mafai ona fa'afefe i le vai, ethanol ma acids. Solu i totonu o le vevela vevela faʻamaʻi sulfuric acid, mago faigofie agglomerate. 600 C ma kaponi e mafai ona faʻaititia ile barium sulfide.
Fa'aoga	E masani ona faʻaaogaina e fai ma sui faʻamamafa mo le suauʻu ma le kesi faʻalenatura palapala palapala, ma o se mea taua minerale mataʻutia mo le suʻeina o le barium uʻamea ma le saunia o mea eseese o le barium. O mea sili ona taua o le barium i totonu o pisinisi o le barium carbonate, barium chloride, sulfuric acid, barium nitrate, barium hydroxide, barium oxide, barium peroxide, barium chromate, Barium manganate, barium chlorate, lithopone, barium polysulfide, ma isi. e pei o mea mata ma faatumu mo paʻu, palasitika, pigments, faʻapipiʻi, fai pepa, ie, vali, vaitusi, eletise; Fa'aaogaina e pei o le ga'o fa'avae o le barium, fa'amamaina o le suau'u, suka beet, mea mata Rayon; Fa'aaogaina e pei o vaila'au fa'ama'i, sterilants, rodenticides, mea pāpā, Green pyrotechnic, pomu fa'ailo, su'esu'e, fa'ailo ata pue X-ray fa'afoma'i; Faʻaaogaina foi i tioata, ceramics, paʻu, mea tau eletise, mea faufale, metallurgy ma isi matagaluega. E mafai ona faʻaogaina le uʻamea Barium mo televise ma moni

Folasaga

E leai se tofo, e le oona. Fa'aleagaina i luga ole 1600 ℃. Solu i totonu o le vevela sulfuric acid, e le mafai ona solu i le vai, organic ma inorganic acids, vaifofo caustic, soluble i le vevela sulfuric acid ma vevela concentrated sulfuric acid. O mea tau vailaʻau e mautu, ma e faʻaititia i le barium sulfide e ala ile vevela ile kaponi. E le suia le lanu pe a faʻaalia i le hydrogen sulfide poʻo kasa oona i le ea.
