Introduction
The coagulation of colloidal particles plays an essential role during various processes, including the production of materials for structural and the implementation of nanotechnology processes. The sol-gel with select physical, optical, magnetic, and electrical properties, like e.g., particles and their processing of nanostructured materials. properties of the resulting materials. An aggregate is a collection of particles with strong interparticle particles. In this case, the resulting surface area of the formed that allow a direct approach to the physical and mathematical modeling of colloidal processes associated with coagulation and aggregation of in mind that they often proceed together.One of the main processes leading to the interaction of colloidal particles with each other is Brownian coagulation. Colloidal particles react to random molecular therefore, they remain in irregular (Brownian) motion all the time. coagulation of colloidal particles. interaction of colloidal particles. The Brownian walk of particles leads with each other. It also promotes their deposition on the surface of various materials. However, large particles and their aggregates are simultaneously with the convective transfer of small particles and During the sedimentation of large aggregates of colloidal particles, the surface of the aggregate, the standard component of the solvent H uHFW SOD\V D VLJQLquotesdbs_dbs1.pdfusesText_1[PDF] formation ecole des mines
