Barium Acetate 99.5% CAS 543-80-6
Barium acetate yog ntsev ntawm barium (II) thiab acetic acid nrog tshuaj lom neeg BA (C2h3o2) 2. Nws yog cov hmoov dawb uas yog soluble heev hauv dej, thiab decomposes rau barium oxide rau cua sov. Barium acetate muaj lub luag haujlwm ua mordant thiab catalyst. Acetates yog cov khoom ua ntej zoo rau kev tsim khoom ntawm Ultra High sib txuas, catalysts, thiab cov ntaub ntawv nanoscale.

Barium hydroxide (Barium Dihydrehide) BA (Oh) 2 ∙ 8H2O 99%
Barium hydroxide, ib qho tshuaj sib txuas nrog cov mis nyujBa(Oh) 2, yog dawb cov khoom siv, soluble hauv dej, kev daws tau hu ua cov dej barite, muaj zog alkaline. Barium hydroxide muaj lwm lub npe, uas yog: caustic barite, barium hydrate. Monohydrate (X = 1), hu ua baryta los yog baryta-dej, yog ib tug ntawm tus thawj coj ntawm lub xeev barium. Qhov no dawb granular monohydrate yog daim foos lag luam ib txwm muaj.Barium hydroxide Octahydrate, raws li cov dej khov kho insolubble crystalline barium tau, yog ib qho tshuaj tsw qab yog ib qho ntawm cov tshuaj muaj kev phom sij tshaj plaws hauv chav kuaj.BA (OH) 2.8H2Oyog ib qho tsis muaj kob uas nyob ntawm chav tsev kub. Nws muaj qhov ntom ntom ntawm 2.18g / CM3, dej soluble thiab acid, lom, tuaj yeem ua kev puas tsuaj rau lub paj hlwb thiab lub plab zom mov.BA (OH) 2.8H2Oyog corrosive, tej zaum yuav ua rau hlawv qhov muag thiab tawv nqaij. Tej zaum nws yuav ua rau cov zom zom zom kom zoo nkauj yog tias nqos tau. Piv txwv li cov tshuaj tiv thaiv: • BA (Oh) 2.8H2O + 2NH4SCN = BA (SCN) 2 + 10h2o + 2NH3
