Particle aggregation

The aggregation is a ( loose ) assembly of atoms, molecules and / or ions to a larger association, the aggregate. The common storage is caused by van der Waals forces, intermolecular forces and other types of chemical bonds. If the units are made ​​up of molecules of the same, we speak of association and associates.

In a wider sense can also be crystalline or amorphous primary particles into larger aggregates, which means the bonded particles coalesce or agglomerate. Then consists in dispersing the particular need to " grind " these aggregates by mechanical force again.
