agglomeration (except in polymer science)

Also contains definitions of: coagulation, flocculation
https://doi.org/10.1351/goldbook.A00182
Process of contact and adhesion whereby dispersed particles are held together by weak physical interactions ultimately leading to @P04534@ by the formation of precipitates of larger than @C01172@ size.
Notes:
  1. Agglomeration is a reversible process.
  2. The definition proposed here is recommended for distinguishing agglomeration from aggregation.
