  • I-Barium Acetate 99.5% Cas 543-80-6

    I-Barium Acetate 99.5% Cas 543-80-6

    I-Barium acetate ityuwa ye-barium (II) kunye ne-acetic acid kunye ne-chemical formula Ba (C2H3O2) 2. Ingumgubo omhlophe onyibilikayo kakhulu emanzini, kwaye ubole kwi-Barium oxide xa ufudumeza. I-Barium acetate inendima njenge-mordant kunye ne-catalyst. I-acetates zi-precursors ezigqwesileyo zokuvelisa i-ultra high purity compounds, ii-catalysts, kunye ne-nanoscale materials.

  • IBarium Hydroxide (Barium Dihydroxide) Ba(OH)2∙ 8H2O 99%

    IBarium Hydroxide (Barium Dihydroxide) Ba(OH)2∙ 8H2O 99%

    I-Barium hydroxide, i-chemical compound kunye ne-chemical formulaBa(OH)2, yinto emhlophe eqinileyo, enyibilikayo emanzini, isisombululo kuthiwa ngamanzi e-barite, i-alkaline eyomeleleyo. I-Barium Hydroxide inelinye igama, elithi: caustic barite, barium hydrate. I-monohydrate (x = 1), eyaziwa ngokuba yi-baryta okanye i-baryta-water, enye yeenqununu eziphambili ze-barium. Le monohydrate emhlophe yegranular yindlela eqhelekileyo yorhwebo.IBarium Hydroxide Octahydrate, njengomthombo we-crystalline we-crystalline ongenakunyibilika kakhulu wamanzi, yi-inorganic chemical compound enye yeekhemikhali eziyingozi kakhulu ezisetyenziswa kwilabhoratri.Ba(OH)2.8H2Oyikristale engenambala kubushushu begumbi. Inobunzima be-2.18g / cm3, i-soluble yamanzi kunye ne-asidi, inetyhefu, inokubangela umonakalo kwi-nervous system kunye nenkqubo yokugaya.Ba(OH)2.8H2Oinomhlwa, inokubangela ukutshisa kwamehlo kunye nolusu. Inokubangela ukucaphuka komjelo wokwetyisa ukuba iginyiwe. Iimpendulo zomzekelo: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3

  • I-Barium Carbonate(BaCO3) Umgubo 99.75% CAS 513-77-9

    I-Barium Carbonate(BaCO3) Umgubo 99.75% CAS 513-77-9

    I-Barium Carbonate yenziwe kwi-barium sulfate yendalo (barite). I-Barium Carbonate umgubo oqhelekileyo, umgubo ocolekileyo, umgubo orhabaxa kunye negranular zonke zinokwenziwa ngokwezifiso kwi-UrbanMines.
