Ammonium Metatungstate Hydrate Description

Ammonium metatungstate hydrate, tseem hu ua AMT, yog cov tshuaj tungsten nyob rau hauv daim ntawv ntawm cov muaj kuab heev soluble hydrated. AMT yog tsim los ua -10 mesh hmoov kom tau raws li qhov xav tau nruj hauv cov catalyst, kev kho mob, semiconductor, thiab lwm yam kev lag luam siab. AMT kuj tseem siv rau hauv kev tshawb fawb cov ntaub ntawv thiab hauv analytical chemistry. Nyob rau hauv chav tsev kub, cov tshuaj aqueous tuaj yeem saturated txog 70 feem pua ​​​​ntawm qhov hnyav ntawm WO3. SSC muab cov purity sib txawv thiab customized ntim ammonium metatungstate hydrate hmoov.

Ammonium metatungstate hydrate yog ib qho ntawm ntau cov organo-metallic compounds (tseem hu ua metalorganic, organo-inorganic thiab metallo-organic compounds) muag los ntawm SSC rau kev siv uas yuav tsum tsis muaj dej solubility xws li hnub ci zog thiab kev kho dej tsis ntev los no. Cov txiaj ntsig zoo sib xws kuj tuaj yeem ua tiav nrog nanoparticles thiab los ntawm nyias zaj duab xis tso tawm. SSC tseem muab ntau yam ntaub ntawv los ua kev daws teeb meem. Ammonium metatungstate hydrate feem ntau tam sim ntawd muaj nyob rau hauv feem ntau ntim. High purity, submicron thiab nanopowder cov ntaub ntawv yuav raug txiav txim siab. Muaj cov ntaub ntawv qhia txog kev txawj ntse, kev tshawb fawb thiab kev nyab xeeb ntxiv.
