| 摘要 |
The present invention relates to a method of preparing fine powder, and more specifically to a method of preparing fine powder particles in much finer powder form with high purity by grinding high purity natural silica to prepare silicate (SiO<SUB>3</SUB>) capable of being dissolved in water and dissolving the silicate in water, distilling it under reduced pressure to obtain a porous structure with high purity silicate (SiO<SUB>3</SUB>), and grinding the obtained porous structure again. |
