Nano particle size tungsten trioxide for manufacturing ceramic microsphere may be prepared by hydrothermal reaction using Na2WO4?2H2O, urea and concentrated hydrochloric acid as raw materials. In this process, the NH4+ produced by urea decomposition makes the metastable hexagonal phase tungsten trioxide stable. Therefore, it is necessary to study the effect of urea on the crystal structure of tungsten trioxide after stirring at room temperature under hydrothermal treatment. After the addition of urea, the solution was stirred at room temperature for…
