What Is Nanoparticle Agglomeration? A single crystal grain or amorphous sphere obtained from synthesis is called a primary particle; when several primary particles touch and bind together into a larger unit, an agglomerate is formed. Agglomerates are usually divided into two classes according to the strength of the bonding: soft agglomerates are held together mainly by weak physical interactions s...
