I-Barium Hydroxide (i-Barium Dihydroxide) i-Ba(OH)2∙ 8H2O 99%
I-Barium hydroxide, ikhemikhali equlethe ifomula yekhemikhaliBa(OH)2, yinto emhlophe eqinileyo, enyibilikayo emanzini, isisombululo sibizwa ngokuba ngamanzi e-barite, i-alkaline enamandla. I-Barium Hydroxide inelinye igama, elileli: i-caustic barite, i-barium hydrate. I-monohydrate (x = 1), eyaziwa ngokuba yi-baryta okanye i-baryta-water, yenye yezona zinto ziphambili ze-barium. Le monohydrate emhlophe eneegranular yindlela eqhelekileyo yorhwebo.I-Barium Hydroxide Octahydrate, njengomthombo we-Barium ocwebezelayo onganyibilikiyo emanzini kakhulu, yikhemikhali engabonakaliyo engenye yeekhemikhali eziyingozi kakhulu ezisetyenziswa kwilabhoratri.I-Ba(OH)2.8H2Oyikristale engenambala kubushushu begumbi. Inobunzima obuyi-2.18g / cm3, iyanyibilika emanzini kwaye ine-asidi, inetyhefu, inokubangela umonakalo kwinkqubo yemithambo-luvo kunye nenkqubo yokugaya ukutya.I-Ba(OH)2.8H2Oiyatsha, inokubangela ukutsha emehlweni naselusu. Inokubangela ukurhawuzelelwa kwendlela yokugaya ukutya ukuba iginyiwe. Umzekelo weempendulo: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3

I-Barium Acetate 99.5% Cas 543-80-6
I-Barium acetate yityuwa ye-barium (II) kunye ne-acetic acid enefomyula yekhemikhali i-Ba (C2H3O2)2. Yipowder emhlophe enyibilikayo kakhulu emanzini, kwaye ibola ibe yi-Barium oxide xa ifudunyezwa. I-Barium acetate inendima njenge-mordant kunye ne-catalyst. Ii-Acetate zizinto eziphambili zokuvelisa iikhompawundi ezicocekileyo kakhulu, ii-catalysts, kunye nezinto ze-nanoscale.

Umgubo weBarium Carbonate (BaCO3) 99.75% CAS 513-77-9
I-Barium Carbonate yenziwe nge-barium sulfate yendalo (i-barite). I-Barium Carbonate powder eqhelekileyo, umgubo ocolekileyo, umgubo oqinileyo kunye ne-granular zonke zingenziwa ngokwezifiso e-UrbanMines.
