Term: precipitation
https://doi.org/10.1351/goldbook.PT07627

Definition:
sedimentation of a solid material (a precipitate) from a liquid solution in which the material is present in amounts greater than its solubility in the liquid.

Note: When @P04795@ occurs in @S05727@-@G02600@ processing, @S05727@ particles have aggregated to a size where gravitational forces cause them to sink or float. Generally, aggregation arises from a change in the @S05727@ that reduces the interparticle repulsion.
