  • Tungsten(VI) Oxide Powder (Tungsten Trioxide & Blue Tungsten Oxide)

    Tungsten(VI) Oxide Powder (Tungsten Trioxide & Blue Tungsten Oxide)

    Tungsten(VI) Oxide, yomwe imadziwikanso kuti tungsten trioxide kapena tungstic anhydride, ndi mankhwala omwe ali ndi okosijeni ndi tungsten zitsulo. Amasungunuka muzitsulo zotentha za alkali. Zosasungunuka m'madzi ndi ma acid. Kusungunuka pang'ono mu hydrofluoric acid.

  • Tungsten Carbide ufa wabwino wa imvi Cas 12070-12-1

    Tungsten Carbide ufa wabwino wa imvi Cas 12070-12-1

    Tungsten Carbidendi membala wofunikira m'gulu la ma inorganic compounds a carbon. Amagwiritsidwa ntchito yokha kapena ndi 6 mpaka 20 peresenti ya zitsulo zina kuti azitha kulimba poponya chitsulo, kudula m'mphepete mwa macheka ndi kubowola, ndi zitsulo zoboola zida.

  • Cesium Tungsten Bronzes(Cs0.32WO3) Assay Min.99.5% Cas 189619-69-0

    Cesium Tungsten Bronzes(Cs0.32WO3) Assay Min.99.5% Cas 189619-69-0

    Cesium Tungsten Bronzes(Cs0.32WO3) ndi chinthu chapafupi cha infrared chotengera nano chokhala ndi tinthu tating'ono komanso kubalalika kwabwino.Cs0.32WO3ili ndi ntchito yabwino kwambiri yotchinga pafupi ndi infrared komanso ma transmittance owoneka bwino kwambiri. Imayamwa mwamphamvu m'dera lapafupi ndi infrared (wavelength 800-1200nm) komanso kufalikira kwakukulu kudera lowala lowoneka (wavelength 380-780nm). Tili ndi kaphatikizidwe bwino kwambiri crystalline ndi mkulu chiyero Cs0.32WO3 nanoparticles kudzera kutsitsi pyrolysis njira. Pogwiritsa ntchito sodium tungstate ndi cesium carbonate monga zopangira, cesium tungsten bronze (CsxWO3) ufa adapangidwa ndi kutentha kochepa kwa hydrothermal reaction ndi citric acid monga kuchepetsa.
