  2. Dispersion (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(chemistry)

    Dispersion is a process by which (in the case of solid dispersing in a liquid) agglomerated particles are separated from each other, and a new interface between the inner surface of the liquid dispersion medium and the surface of the dispersed particles is generated. This process is facilitated by molecular diffusion and convection. [4]

  3. Colloid - Wikipedia

    en.wikipedia.org/wiki/Colloid

    Aggregation causes sedimentation or creaming, therefore the colloid is unstable: if either of these processes occur the colloid will no longer be a suspension. Examples of a stable and of an unstable colloidal dispersion. Electrostatic stabilization and steric stabilization are the two main mechanisms for stabilization against aggregation.

  4. Suspension (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Suspension_(chemistry)

    In chemistry, a suspension is a heterogeneous mixture of a fluid that contains solid particles sufficiently large for sedimentation. The particles may be visible to the naked eye, usually must be larger than one micrometer, and will eventually settle, although the mixture is only classified as a suspension when and while the particles have not ...

  5. Particle aggregation - Wikipedia

    en.wikipedia.org/wiki/Particle_aggregation

    Particle agglomeration refers to the formation of assemblages in a suspension and represents a mechanism leading to the functional destabilization of colloidal systems. . During this process, particles dispersed in the liquid phase stick to each other, and spontaneously form irregular particle assemblages, flocs, or agglom

  6. Sedimentation equilibrium - Wikipedia

    en.wikipedia.org/wiki/Sedimentation_equilibrium

    As an example, consider a colloidal suspension of polyethylene particles in water, and three different values for the diameter of the particles: 0.1 μm, 1 μm and 10 μm. The volume of a colloidal particles can be calculated using the volume of a sphere V = 4 3 π R 3 {\displaystyle V={\frac {4}{3}}\pi R^{3}} .

  7. Depletion force - Wikipedia

    en.wikipedia.org/wiki/Depletion_force

    When both large colloidal particles and small depletants are in a suspension, there is a region which surrounds every large colloidal particle that is unavailable for the centers of the depletants to occupy. This steric restriction is due to the colloid-depletant hard-sphere potential. [7] [8] The volume of the excluded region is

  8. Talk:Suspension (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Talk:Suspension_(chemistry)

    An example of a suspension would be sand in water. The suspended particles are visible under a microscope and will settle over time if left undisturbed. This distinguishes a suspension from a colloid, in which the suspended particles are smaller and do not settle.[2] " so do the particles in a suspension settle or not? FYI, they do.

  9. Sol (colloid) - Wikipedia

    en.wikipedia.org/wiki/Sol_(colloid)

    A sol is a colloidal suspension made out of tiny solid particles [1] in a continuous liquid medium. Sols are stable, so that they do not settle down when left undisturbed, and exhibit the Tyndall effect, which is the scattering of light by the particles in the colloid. The size of the particles can vary from 1 nm - 100 nm.
