Colloidal Dispersion

Common focus of attention in sciences dealing with colloids, such as the food, pharmaceutical and cosmetic sciences.

A dispersion of one physical material in another, resulting in a discrete set of particles disconnected from themselves but connected at all points to a continuous phase.

Examples include:

• Emulsions (liquid dispersed in liquid)
• Solid foams (gas dispersed in solid)
• Suspensions (solid dispersed in liquid)

A solid matrix after [[porogen]] removal is a less common example.
