Cesium Tungsten Bronzes (Cs0.32WO3) Assay Min.99.5% Cas 189619-69-0
Cesium Tungsten Bronzes(Cs0.32WO3) yog ib qho ze-infrared absorbing nano khoom nrog cov khoom sib xws thiab zoo dispersion.Cs0.32WO3muaj kev ua tau zoo nyob ze-infrared shielding kev ua tau zoo thiab pom lub teeb pom kev zoo.Nws muaj zog nqus nyob rau hauv ze-infrared cheeb tsam (wavelength 800-1200nm) thiab siab transmittance nyob rau hauv lub pom lub teeb cheeb tsam (wavelength 380-780nm).Peb muaj cov synthesis ua tau zoo ntawm cov crystalline thiab siab purity Cs0.32WO3 nanoparticles los ntawm txoj kev tshuaj tsuag pyrolysis.Siv sodium tungstate thiab cesium carbonate ua raw cov ntaub ntawv, cesium tungsten bronze (CsxWO3) hmoov tau tsim los ntawm qhov kub thiab txias hydrothermal cov tshuaj tiv thaiv nrog citric acid ua tus neeg sawv cev txo.
