What is coagulation?

The word coagulation is derived from the Latin "coagulatio" - "coagulation, coagulation", and it describes the physico-chemical process of sticking small particles of a dispersed system into larger ones. Coagulation is carried out under the influence of adhesion forces, and as a result of this process coagulation structures are formed. Let's take a closer look at what is coagulation, and also consider the features of the process.

Colloidal solutions and coagulation

A colloidal solution (other names - sol, lyozol) is a highly dispersed system with a liquid or gaseous dispersed medium, in the volume of which the dispersed phase is distributed, usually in the form of liquid droplets. Any aerosol is an example of a colloidal system.

Coagulation is a typical process for colloidal systems, and two types of coagulation are distinguished: either one of the dispersed phases precipitates or it completely solidifies into a gel. Why does coagulation occur? As a rule, it is caused by a violation of the stability of a colloidal solution, to which, for example, thermal or mechanical effects may become prerequisites.


Anticoagulants are substances that, as the name implies, interfere with the coagulation process. Preparations with anticoagulants are often prescribed to patients with high prothrombin factor, that is, to put it simply, �thick� blood.
