Hydroxide yake, yomwe imadziwika mu mbiri yamakono yamakono monga Barryta, sizichitika ngati mchere, koma amatha kukonzekera potenthedwa, koma amatha kukonzekera potenthetsa, koma amatha kukonzekera potenthedwa pogwiritsa ntchito barium carbonate.
Mapulogalamu: Chitsulo ndi zowongolera, zokhala zowonera; Groad-tin altaning - kuti muwonjezere kukana; Aloy ndi Nickel ya mapulagini; Zowonjezera zitsulo ndikupangitsa chitsulo ngati infolant; Maytows ndi calcium, manganese, silicon, ndi aluminiyamu ngati ma deoxizer a gradeel.Barum ali ndi ntchito zochepa chabe zopangira mafakitale. Zitsulo zakhala zikugwiritsidwa ntchito mwachisawawa kuti zikhale mpweya wochepa ma tubes. Ndi gawo la YBCO (Supercondecturedicturedicts) ndi Electro Conramics, ndipo imawonjezeredwa ndi chitsulo ndikuchepetsa kukula kwa mpweya mkati mwa microst ya chitsulo.
Barium, ngati chitsulo kapena chizingwe cholumikizirana ndi aluminiyamu, chimagwiritsidwa ntchito pochotsa mipweya yosafunikira kuchokera ku machubu a vacuum, monga mazira a TV.
