  • I-Tungsten(VI) Umgubo weOksidi (iTungsten Trioxide kunye neBlue Tungsten oxide)

    I-Tungsten(VI) Umgubo weOksidi (iTungsten Trioxide kunye neBlue Tungsten oxide)

    I-Tungsten (VI) i-Oxide, eyaziwa ngokuba yi-tungsten trioxide okanye i-tungstic anhydride, i-chemical compound equkethe i-oksijini kunye ne-tungsten yensimbi yenguqu. Iyanyibilika kwizisombululo zealkali ezishushu. Ayinyibiliki emanzini kunye neeasidi. Inyibilika kancinci kwi-hydrofluoric acid.

  • I-Tungsten Carbide ecolekileyo umgubo ongwevu Cas 12070-12-1

    I-Tungsten Carbide ecolekileyo umgubo ongwevu Cas 12070-12-1

    ITungsten Carbidelilungu elibalulekileyo lodidi lweekhompawundi ze-inorganic zekhabhoni. Isetyenziswa yodwa okanye kunye nezinye iintsimbi ezi-6 ukuya kwezingama-20 ekhulwini ukuze kufakwe intsimbi eqinile, isarha nokubhobhoza, kunye neentsimbi ezigqobhozayo.

  • 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

    IiBronzi zeCesium Tungsten(Cs0.32WO3) yinto ekufutshane ne-infrared efunxayo ye-nano kunye namasuntswana afanayo kunye nokusabalalisa okulungileyo.Cs0.32WO3inomsebenzi obalaseleyo wokhuselo olukufuphi ne-infrared kunye nokuhanjiswa kokukhanya okuphezulu okubonakalayo. Inokufakwa okunamandla kwindawo ekufutshane ne-infrared (i-wavelength 800-1200nm) kunye nokuhanjiswa okuphezulu kwindawo yokukhanya ebonakalayo (i-wavelength 380-780nm). Sine-synthesis eyimpumelelo ye-crystalline ephezulu kunye nokucoceka okuphezulu kwe-Cs0.32WO3 nanoparticles ngokusebenzisa indlela yokutshiza i-pyrolysis. Ukusebenzisa i-sodium tungstate kunye ne-cesium carbonate njengezinto eziluhlaza, i-cesium tungsten bronze (i-CsxWO3) i-powders yenziwe ngokusabela okuphantsi kwe-hydrothermal kunye ne-citric acid njenge-agent yokunciphisa.
