What is the Difference Between Aggregation and Agglomeration?

Aggregation and agglomeration are two different processes that involve the formation of clusters of particles. The key difference between the two lies in the bonding between the particles and the density and size of the clusters formed.

Aggregation:

• Aggregation is the process of forming clusters of particles via gathering small particles by strong chemical forces.
• The end product of this process is an "aggregate," which is a dense cluster of particles due to the strong bonds between them.
• Aggregates are typically smaller than agglomerates because of the strong chemical forces holding the particles together.

Agglomeration:

• Agglomeration is the process of forming clusters of particles via gathering small particles by weaker forces, such as van der Waals forces or electrostatic attraction.
• The end product of this process is an "agglomerate," which is a loose arrangement of primary particles or aggregates, or a mixture of the two.
• Agglomerates are usually larger than aggregates due to the weaker forces holding the particles together, allowing for a more open structure.

In summary, aggregation and agglomeration both involve the formation of clusters of particles, but they differ in the bonding between the particles and the density and size of the clusters formed. Aggregation involves strong chemical forces, resulting in dense clusters of particles (aggregates), while agglomeration involves weaker forces, leading to loose assemblies of particles (agglomerates).
