Koagulative

Koagulative is a term used to describe phenomena related to coagulation. It denotes processes and properties by which a liquid, colloidal suspension, or sol becomes more solid through mechanisms such as cross-linking, aggregation, or precipitation. The spelling Koagulative is encountered mainly in non-English language texts or as an alternate transliteration; in English, the standard form is coagulative. In some contexts the term is used descriptively rather than as a fixed technical definition, leaving its scope to be clarified by the surrounding field.

In medicine and biology, coagulation refers to the cascade that leads to clot formation and hemostasis. Koagulative terminology is sometimes employed in cross-disciplinary discussions to emphasize the physical transition from liquid to solid matter, including clot formation, fibrin network generation, or abnormal clotting states. It is important to distinguish this broader usage from coagulative necrosis, a specific tissue pathology describing preserved cell outlines in dying tissue despite loss of nuclei.

In materials science and chemistry, koagulative processes describe the aggregation and solidification of dispersed particles. Examples include coagulative precipitation in which a change in solvent conditions drives particles to come out of solution, yielding a solid phase, and gelation where a liquid becomes a gel through cross-linking. The term is used to convey the underlying mechanism rather than a particular material.
