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

    ʻO Tungsten(VI) Oxide, i ʻike ʻia ʻo tungsten trioxide a i ʻole tungstic anhydride, he mea hoʻohui kemika i loaʻa ka oxygen a me ka tungsten metala hoʻololi. Hiki ke hoʻoheheʻe ʻia i loko o nā hāleʻa alkali wela. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai a me nā waikawa. Hiki ke hoʻoheheʻe ʻia i loko o ka waika hydrofluoric.

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

    ʻO Cesium Tungsten Bronzes(Cs0.32WO3) he mea hoʻoheheʻe kokoke i ka infrared me nā ʻāpana like ʻole a me ka hoʻopuehu maikaʻi.Cs0.32WO3Loaʻa i ka hana pale kokoke-infrared maikaʻi loa a me ke kiʻekiʻe o ka transmittance māmā. Loaʻa iā ia ka absorption ikaika i ka ʻāina kokoke-infrared (ka lōʻihi o ka nalu 800-1200nm) a me ka transmittance kiʻekiʻe ma ka ʻāpana kukui ʻike ʻia (ka lōʻihi o ka nalu 380-780nm). Loaʻa iā mākou ka synthesis kūleʻa o ka crystalline kiʻekiʻe a me ka maʻemaʻe kiʻekiʻe Cs0.32WO3 nanoparticles ma o kahi ala pyrolysis spray. Me ka hoʻohana ʻana i ka sodium tungstate a me ka cesium carbonate ma ke ʻano he mea maka, ua hana ʻia nā pauka cesium tungsten bronze (CsxWO3) e ka hopena hydrothermal haʻahaʻa me ka waikawa citric ma ke ʻano he mea hoʻemi.
