| titleOfInvention | Method for continuously and controllably preparing nano silicon dioxide spherical particles |
| abstract | The invention provides a method for continuously and controllably preparing nano silicon dioxide spherical particles, which comprises the following steps: alcohols are used as a dispersing agent, organic silicon and silicate are used as silicon sources, the nano silicon dioxide spherical particles are obtained by hydrolysis under the action of an alkaline catalyst, and solid products are obtained by drying treatment. The preparation process mainly comprises the following steps: and introducing the silicon source solution and the catalyst into a micro-channel mixer for intensive mixing, then heating to a certain temperature at high strength, and aging for a certain time to directly obtain nano-silica finished particles with different scales. The method of the invention is characterized in that: the method can prepare the high-purity silicon dioxide particles with the particle size of 10-1000nm, high sphericity and uniform PDI (degree of homogeneity) range of 0.02-0.3, and has the advantages of high efficiency, uniform product particles, controllable nanoscale, high yield, easiness in amplification and capability of realizing continuous production. |
