DISPERSE SYSTEMS

From Big Medical Encyclopedia

DISPERSE SYSTEMS (Latin dispersio dispersion) — the heterogeneous systems consisting of a continuous gaseous, fluid or solid medium (dispersion medium) in a cut are distributed particles of the crushed substance or several substances (dispersed phase). Owing to strongly developed interface of phases D. of page have the considerable free superficial energy causing their thermodynamic instability, high adsorptive capacity and raised chemical and biol, activity.

Of page are eurysynusic in the nature: all microorganisms, cells and fabrics of macroorganisms concern to them. These systems are the main object of studying of colloid chemistry.
