| titleOfInvention | Preparation method of nano silicon dioxide microspheres with particle size of 10-20nm |
| abstract | The invention discloses a preparation method of nano silicon dioxide microspheres with particle sizes of 10-20nm, which relates to the technical field of inorganic oxide processing, and takes tetraethoxysilane as a silicon source, prepares nano silicon dioxide through hydrolysis reaction under the combined action of ammonia water, ethanol and water, and leads the prepared nano silicon dioxide microspheres to present unique advantages of regular sphere, good monodispersity and narrow particle size distribution range through the addition of N-hydroxymethyl acrylamide, thereby avoiding the problems of irregular sphere, poor monodispersity and wide particle size distribution range of the prepared nano silicon dioxide in the conventional technical scheme for preparing nano silicon dioxide, and further meeting the market demand for the nano silicon dioxide microspheres with particle sizes of 10-20 nm. |
