Method for producing spherical silicon fine particles with narrow particle size distribution |
| abstract |
The present invention relates to a method for producing spherical silicon microparticles, and more particularly to preparing an alkaline aqueous solution containing a nonionic dispersant; Adding and stirring a silane compound having a structure of R 1 Si (X) 3 to the aqueous solution at a uniform rate; And condensation-polymerizing the mixture by stirring and heating to form spherical silicon fine particles. The silicon fine particles produced according to the present invention are spherical silicon fine particles having a narrow particle size distribution and a very small particle diameter. In particular, monodisperse spherical silicon fine particles of 1 μm or less can be prepared by hydrolysis and polycondensation of organotrialkoxysilane by a simple method of adding organotrialkoxysilane to an alkaline aqueous solution containing a nonionic dispersant. have. |
