Dispersion is a chemical term for a combination in which tiny particles of one component are dispersed into another. In general, particles in a solution are molecular or ionic in size; those in a colloid are bigger but too small to be seen with an ordinary microscope. Those in a suspension may be seen under a microscope or ...

Colloidal Solution - Definition, Types, Properties and Examples
WebIn this study, coarse-graining methods of a three-dimensional CFD-DEM model are developed to investigate the sand production phenomenon. The modified cohesive contact model is utilized for the simulations with a sample based on particle size distribution obtained from the unconsolidated sandstone reservoir in Kazakhstan. The substance which is dispersed as very fine particles in a solution is called the dispersed phase. In a colloidal solution, a dispersed phase is suspended in the dispersion medium. A colloid solution does not possess a uniform mixture. It means that the particles of the dispersed phase are present in the … See more On the basis of the dispersed phase type, colloids are classified into various types that include sol, emulsion, foam and aerosol. 1. Sol – Sol is a colloidal suspension of solid particles in a liquid. For example, Ruby … See more Based on the nature of the minute particles of the dispersed phase, the colloids are mainly divided into three types: 1. Multimolecular colloids 2. Macromolecular Colloids 3. Associated Colloids Let’s … See more The system in which the distributed particles of one material are dispersed in a continuous phase of another material is known as a … See more Dispersion systems are of two types: 1. Molecular Dispersions – Molecular dispersions are referred to as solutions to a solute phase in the solvent.
