Barium ndi mankhwala omwe ali ndi chizindikiro cha Ba ndi nambala ya atomiki 56. Ndi chinthu chachisanu mu Gulu 2, chitsulo chofewa cha silvery alkaline earth.Chifukwa cha kuchuluka kwake kwamankhwala, barium sichipezeka m'chilengedwe ngati chinthu chaulere.Hydroksidi yake, yomwe imadziwika kale m'mbiri yakale monga baryta, sichipezeka ngati mchere, koma ikhoza kukonzedwa ndi kutentha kwa barium carbonate.
Mapulogalamu: Zitsulo ndi aloyi, kubala aloyi;lead-tin soldering alloys - kuwonjezera kukana kukwawa;aloyi ndi nickel kwa spark plugs;zowonjezera zitsulo ndi chitsulo choponyedwa ngati inoculant;ma aloyi okhala ndi calcium, manganese, silicon, ndi aluminiyamu ngati ma deoxidizer achitsulo apamwamba kwambiri.Barium ili ndi ntchito zochepa zamafakitale.Chitsulochi chakhala chikugwiritsidwa ntchito potaya mpweya m'machubu a vacuum.Ndi gawo la YBCO (high-temperature superconductors) ndi ma electro ceramics, ndipo amawonjezeredwa ku chitsulo ndi chitsulo chosungunula kuti achepetse kukula kwa mbewu za kaboni mkati mwa microstructure yachitsulo.
Barium, ngati chitsulo kapena pamene aloyidwa ndi aluminiyamu, amagwiritsidwa ntchito kuchotsa mpweya wosafunikira (kutsekemera) ku machubu a vacuum, monga machubu a zithunzi za TV.Barium ndiyoyenera kuchita izi chifukwa cha kutsika kwake kwa nthunzi komanso kuyambiranso ku oxygen, nayitrogeni, carbon dioxide, ndi madzi;imatha kuchotseratu mpweya wabwino kwambiri powasungunula mu crystal lattice.Ntchitoyi ikutha pang'onopang'ono chifukwa chakuchulukirachulukira kwa machubu a LCD ndi ma seti a plasma.
