Cocrystallization is a phenomenon where two or more compounds crystallize together to form a new crystal lattice. This process has gained importance in recent years due to its potential in the field of pharmaceuticals and materials science. However, if you are looking for synonyms for this word, some alternatives could be co-crystallization, crystal co-formation, and multi-component crystal formation. Another phrase commonly used is molecular complexation or molecular association since cocrystallization often occurs due to intermolecular interactions between the co-forming compounds. The use of synonyms can help in expanding your vocabulary and make your writing or research more interesting.
