Nano grain size tungstic acid may be synthesized by chemical precipitation method using ammonium metatungstate (AMT) and hydrochloric acid (HCL) as raw materials, and the agglomeration of nanoparticles may be effectively improved with the addition of ethanol. And nano tungstic acid with high purity, small particle size and good dispersion may be prepared by liquid phase precipitation method in the alcohol-water system. Synthesis of Monodisperse Tungstic Acid Nanoparticles by UV Irradiation Monodisperse tungstic acid nanoparticles with an average particle size…
