Exploring the Factors that Influence Crystal Formation

This article explores how different factors such as type of crystallizing substance, concentration, temperature, agitation and impurities present in the solution affect crystal formation and size.

Exploring the Factors that Influence Crystal Formation

The formation and size of crystals are determined by a variety of factors, including the type of crystallizing substance, its concentration, temperature, agitation, and any impurities present in the solution. The rate of crystal formation and the total size of the crystallization tank also play a role. For example, it is impossible to grow a large crystal in a small cup. On the other hand, in a larger tank, molecules need to travel a longer path to reach each other or to reach the seed crystal, thus increasing the crystallization time.

Crystallization is essential for making icings, icings or candies such as fondant and fudge. It begins with the development of nuclei in the fluid, followed by the addition of material in solution to these cores. The type of crystallization material, concentration, temperature, agitation and contaminants present in the solution all influence the rate of production and crystallization of the cores. Generally speaking, slower crystal formation leads to larger crystals.

The individual molecules of a solute must move and bind to any other molecule or to a seed crystal at a given position and angle for a crystal to form. Impurities can also affect this process as they are solutions of other crystals that naturally have a tendency to move away from the target crystal. Crystals that form near or on the surface tend to crystallize faster and thus tend to be smaller. The size of crystals can also be affected by agitation.

In agitated solutions, molecules do not have enough time to move and bind together, resulting in smaller crystals than those formed naturally. This project is an opportunity to explore the incredible world of crystals and do some experiments to make crystals. The rate of crystallization is calculated by dividing the weight of the final crystals by the total weight of the mixture or solution. Temperature is another factor that affects crystal growth.

Generally speaking, higher temperatures lead to thicker crystals. At low temperatures (5°C to 10°C), crystals formed from salts such as barium nitrate, strontium nitrate and lead nitrate have a very simple habit; however, they become increasingly complex with increasing temperature. Finally, if small crystals are desired, it is necessary to mix candies and glazed syrups until almost all of the material has crystallized.
