Patent ID: 11661526

Abstract:
A method for obtaining at least one particle, including: (a) preparing solution A including at least one precursor of at least one of Si, B, P, Ge, As, Al, Fe, Ti, Zr, Ni, Zn, Ca, Na, Ba, K, Mg, Pb, Ag, V, Te, Mn, Ir, Sc, Nb, Sn, Ce, Be, Ta, S, Se, N, F, and Cl; (b) preparing aqueous solution B; (c) forming droplets of solution A; (d) forming droplets of solution B; (e) mixing droplets; (f) dispersing mixed droplets in a gas flow; (g) heating dispersed droplets to obtain the at least one particle; (h) cooling the at least one particle; and (i) separating and collecting the at least one particle. The aqueous solution is acidic, neutral, or basic. In step (a) and/or step (b) at least one colloidal suspension of a plurality of nanoparticles is mixed with the solution. Also, a device for implementing the method.
