Ammonium Paratungstate Nqe lus piav qhia
Ammonium paratungstate (APT) yog dawb crystalline ntsev nrog cov tshuaj formula (NH4)10(H2W12O42) · 4H2O. Nws tau piav qhia tias yog "cov khoom siv tseem ceeb tshaj plaws rau txhua yam khoom siv tungsten." Nws yog cov khoom siv raw ntawm sodium tungstate thiab tungsten trioxide ntau lawm. Ammonium Paratungstate feem ntau tam sim no muaj nyob rau hauv ntau ntim, suav nrog kev txiav txim ntau.
SSC tuaj yeem tsim ammonium paratungstate rau cov kev cai tshwj xeeb los ntawm kev thov, ntxiv rau cov kev cai sib xyaw rau kev lag luam thiab kev tshawb fawb daim ntawv thov thiab cov cuab yeej tshiab.
Thaum ammonium paratungstate yog rhuab mus rau ntawm 220 thiab 280 degrees Celsius, nws poob ib feem ntawm nws cov ammonium thiab dej compounds, hloov mus rau ammonium metatungstate. Qhov kev sib xyaw tshiab no yog cov ntshiab ntshiab, dej-soluble tungsten hmoov uas yuav luag tsis muaj alkali thiab hlau impurities.
