Tungsten Trioxide Powder Applied for Ceramic Microsphere

Tungsten trioxide powder may be applied to manufacture ceramic microsphere. Thus, these ceramic microspheres have ultra-dispersion in a variety of ceramic systems, thereby greatly improving the weather resistance of the color of the product. And it also has the characteristics of high temperature resistance, acid resistance, alkali resistance, long service life and other characteristics.tungsten trioxide powder applied for ceramic microsphere picture
Study on the Preparation Process of Tungsten Trioxide Powder
Use a certain concentration of sodium tungstate as tungsten source, adjust the pH value of the solution between 1.0~2.5 using hydrochloric acid (HCl), stir 4h in dark place, move it into the 100mL hydrothermal reactor for hydrothermal reaction, and set the temperature of 80~180°C. The reaction product is repeatedly washed with distilled water and absolute ethanol, and then undergoes suction filtration. Finally, it was vacuum dried in a vacuum drying oven at 80°C, and then the synthesized powders under different conditions were subjected to structural characterization and performance tests to determine the basic preparation process of tungsten trioxide powder.
