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

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

    Tungsten(VI) Oxide, oo sidoo kale loo yaqaan tungsten trioxide ama tungstic anhydride, waa iskudhis kiimiko oo ka kooban ogsijiin iyo tungsten birta kala-guurka ah. Waxay ku milmi kartaa xalalka alkali ee kulul. Biyo iyo asiidh ku milma. Waxoogaa ku milmay hydrofluoric acid.

  • Tungsten Carbide budada cawlan ee ganaaxa Cas 12070-12-1

    Tungsten Carbide budada cawlan ee ganaaxa Cas 12070-12-1

    Tungsten Carbidewaa xubin muhiim ah oo ka tirsan fasalka xeryahooda kaarboonka. Waxa loo istcimaalaa kaligaa ama 6 ilaa 20 boqolkiiba biraha kale si loo qaybiyo adkaanta si loo tuuro birta, jarista cidhifyada miinshaarka iyo laylinta, iyo dhexda dhexda madxafyada hubka-muda

  • 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) waa shay nano nuugaya infrared-ku dhow oo leh qaybo isku mid ah iyo kala firdhisanaan wanaagsan.Cs0.32WO3waxay leedahay wax qabad heer sare ah oo gaashaanka infrared-ka ah iyo gudbinta iftiinka sare ee muuqda. Waxay leedahay nuugista xooggan ee gobolka u dhow-infrared (mawjadaha 800-1200nm) iyo gudbinta sare ee gobolka iftiinka muuqda (mawjadaha 380-780nm). Waxaan leenahay synthesis guul of crystalline heer sare ah iyo nadiif sare Cs0.32WO3 nanoparticles iyada oo loo marayo jidka pyrolysis buufin. Isticmaalka sodium tungstate iyo cesium carbonate sida alaabta ceeriin, cesium tungsten bronze (CsxWO3) budada waxaa lagu sameeyay fal-celin heerkul hoose oo biyo ah oo leh citric acid sida wakiilka yaraynta.
