Crystal Formation Through Supersaturation

Description

Crystal formation through supersaturation begins when a solution contains more dissolved solute than it can normally hold. In crystallization, atoms or molecules line up into a rigid crystal lattice so the system can lower its energy. To start the process, the solute concentration and the solution temperature must be adjuste...

Transcript

Crystallization is a phase transformation process where crystals are formed from a source like a cooling saturated solution.

Crystallization begins with primary nucleation, which starts from a clear solution without any pre-existing crystals to aid the process. It is divided into homogeneous and heterogeneous types.

During heteroge...
