emulsion

Examples of emulsion in the following topics:

• Hydrophilic and Hydrophobic Colloids

  • Energy input, through shaking, stirring, or homogenizing, is needed to form the emulsion.
  • Over time, an emulsion tends to separate, because separation puts it in a more stable state.
  • There are three types of instability in emulsions: flocculation, creaming, and coalescence.
  • In B, an emulsion of Phase II dispersed in Phase I has been formed.
  • In C, the unstable emulsion progressively separates.

• Silver

  • The other silver halides used in the manufacture of photographic emulsions are made in the same way, using bromide or iodide salts.
