Chromium Sulfide Description
Chromium sulfide yog inorganic compound nrog cov mis Cr2S3. Nws yog xim av-dub khoom. Chromium sulfides feem ntau yog nonstoichiometric tebchaw, nrog cov qauv xws li CrS mus rau Cr0.67S (xws li Cr2S3). Chromium sulfide tuaj yeem npaj los ntawm cov tshuaj tiv thaiv ntawm stoichiometric sib tov ntawm cov ntsiab lus ntawm 1000 degree. Chromium sulfide hauv dej yuav dhau los ua ob qhov tshuaj tiv thaiv hydrolysis los tsim chromium hydroxide thiab HS-, thiab txawm tias H2S.
Chromium sulfide yog dej nruab nrab thiab acid soluble chromium qhov chaw siv tau tshaj sulfates. Sulfate compounds yog ntsev los yog esters ntawm sulfuric acid tsim los ntawm kev hloov ib los yog ob qho tib si ntawm hydrogens nrog ib tug hlau. Feem ntau cov hlau sulfate tebchaw yog yooj yim soluble hauv dej rau kev siv xws li kev kho dej, tsis zoo li fluorides thiab oxides uas zoo li yuav insoluble. Organometallic cov ntaub ntawv yog soluble nyob rau hauv cov organic daws teeb meem thiab qee zaum nyob rau hauv ob qho tib si aqueous thiab organic daws. Cov hlau ions kuj tseem tuaj yeem raug tshem tawm los ntawm kev tshem tawm lossis coated nanoparticles thiab muab tso rau siv cov hom phiaj thiab cov khoom evaporation rau kev siv xws li cov khoom siv hnub ci zog thiab roj hlwb.
