suspension (rus. суспензия otherwise взвесь) — dispersed system, where solid particles of the dispersed phase are suspended in the liquid dispersed medium.


Suspensions are divided into coarse (with the particle size from 1 micron to a split millimetre) and fine (from 100 to 1,000 nm). Coarse suspensions are unstable and prone to coagulation. Suspensions with the particles moving freely are called sols; if the dispersed particles are bound into a space structure, the suspension is called a gel.

Suspensions are a result of disintegration (grinding of solids in the liquid) or condensation (separation of the solid phase from supersaturated solutions).
