Super Grade Ammonium Paratungstate (APT-0) 834

Super grade ammonium paratungstate is ammonium paratungstate with grade of APT-0, which is divided by national standard. Generally, traditional process to prepare high-purity ammonium paratungstate is first to dissolve super grade ammonium paratungstate by ammonia-dissolving method, and then evaporation recrystallization. The high-purity APT produced by traditional process has the disadvantages as follows: The energy consumption is high and the comprehensive recovery rate of resources is low. Also, equipment and investment are increased when compared with new processing technology, so that…

Grade 1 Ammonium Paratungstate (APT-1) 603

Grade 1 ammonium paratungstate is a national standard product of APT with grade of APT-1. The ammonium paratungstate may be obtained by the process of losing ammonia in ammonium tungstate solution. Its chemical equation is as follows: 12(NH4)2WO4→5(NH4)2O?12WO3?nH2O+(7-n)H2O+14NH3↑ Ammonium tungstate solution is not stable, so that water and ammonia escape when it is heated, and therefore ammonium paratungstate is continuously generated in solution. During this process, ammonium paratungstate changes from unsaturation to saturation to reach a stable state. Under the…
