Synthetic amorphous silica powder and method for producing same |
| abstract |
The synthetic amorphous silica powder of the present invention is obtained by applying a spheroidizing treatment to a granulated silica powder, and by subsequently cleaning and drying it so that the synthetic amorphous silica powder has an average particle diameter D 50 of 10 to 2,000 μm; wherein the synthetic amorphous silica powder has: a quotient of greater than 1.35 and not more than 1.75 obtained by dividing a BET specific surface area of the powder by a theoretical specific surface area calculated from the average particle diameter D 50 ; a real density of 2.10 to 2.20 g/cm 3 ; an intra-particulate porosity of 0 to 0.05; a circularity of 0.50 to 0.75; and an unmolten ratio of greater than 0.25 and not more than 0.60. |
