What is crystallisation?

What is crystallisation?

Crystallisation is the process of formation of crystals. Crystal, the word makes us think of a solid shiny object which may be rare or precious. We performed two experiments to demonstrate crystallisation.

What is the first step of crystallization?

In the first step, a crystalline phase appears from a supercooled liquid or a supersaturated solvent and this step is called nucleation. In the second step, we see a crystal growth i.e., the size of the particles of crystal increases and this step is called a crystal state. Crystallization can help in the separation of chemical solid liquid.

What are the factors affecting the crystallization process?

The nature of a crystallization process is governed by both thermodynamic and kinetic factors, which can make it highly variable and difficult to control. Factors such as impurity level, mixing regime, vessel design, and cooling profile can have a major impact on the size, number, and shape of crystals produced.

How many experiments have been performed on crystallisation?

We performed two experiments to demonstrate crystallisation. Before going into experiments let us understand what are crystals, and the process of crystallisation. A crystal is a chunk of a material in the Solid Form.

What is a salt crystallizer?

Salt crystallizer provides high purity salt for chemical grade, pharmaceutical or food grade salts. It is a high efficiency and energy saving condenser. It operates under vacuum and low-temperature conditions and provides rapid evaporation. It is suitable for crystallization of viscous and highly concentrated materials.

What is the shape of the crystals formed during crystallisation?

The salt obtained during crystallisation is pure and its crystals are large. The shape of crystals can be seen clearly after crystallization. Large crystals of pure substances cannot be formed from their solution.
