Barium Hydroxide (Barium Dihydroxide) Ba(OH)2∙ 8H2O 99%
barium hydroxide, ib qho tshuaj lom neeg uas muaj cov mis tshuajBa(OH)2, yog cov khoom dawb, yaj hauv dej, cov tshuaj hu ua barite dej, muaj zog alkaline. Barium Hydroxide muaj lwm lub npe, uas yog: caustic barite, barium hydrate. Lub monohydrate (x = 1), hu ua baryta lossis baryta-dej, yog ib qho ntawm cov khoom tseem ceeb ntawm barium. Cov monohydrate granular dawb no yog daim ntawv lag luam ib txwm muaj.Barium Hydroxide Octahydrate, ua ib qho crystalline Barium uas tsis yaj hauv dej, yog ib qho tshuaj inorganic uas yog ib qho ntawm cov tshuaj lom neeg txaus ntshai tshaj plaws siv hauv chav kuaj mob.Ba(OH)2.8H2Oyog ib qho siv lead ua tsis muaj xim nyob rau hauv chav tsev kub. Nws muaj qhov ceev ntawm 2.18g / cm3, soluble hauv dej thiab acid, lom, tuaj yeem ua rau puas tsuaj rau lub paj hlwb thiab lub plab zom mov.Ba(OH)2.8H2Oyog corrosive, tej zaum yuav ua rau kub hnyiab rau qhov muag thiab daim tawv nqaij. Nws yuav ua rau mob plab yog tias nqos. Piv txwv li Cov tshuaj tiv thaiv: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3

Barium Acetate 99.5% Cas 543-80-6
Barium acetate yog ntsev ntawm barium (II) thiab acetic acid nrog cov mis tshuaj Ba (C2H3O2) 2. Nws yog hmoov dawb uas yaj tau zoo heev hauv dej, thiab lwj mus ua Barium oxide thaum cua sov. Barium acetate muaj lub luag haujlwm ua mordant thiab catalyst. Acetates yog cov precursors zoo heev rau kev tsim cov tshuaj purity siab heev, catalysts, thiab cov ntaub ntawv nanoscale.
