The csbr melting point determines the temperature at which a solid substance changes from its crystalline state to its liquid state. When heated to a specific temperature, most solids will melt to their liquid phase, whereas a few will remain crystalline and change only slightly in this manner.

The melting point of a solid is an important characteristic of crystalline substances and is often used to spot pure compounds and elements. It is also useful to determine the purity of an organic or inorganic crystalline substance by observing the melting interval of the pure sample versus that of the impure material (melting point depression).

Melting point of a crystalline substance occurs when a substance is heated and it converts from its crystalline state to its liquid state, at which point both the solid and liquid phases exist side-by-side in equilibrium. The energy required to raise the temperature of a solid to its melting point, or to melt it, is known as the heat of fusion.

At the melting point not only the aggregate state but also a large number of other physical characteristics are altered significantly. Amongst them are the thermodynamic values, specific heat capacity, enthalpy and rheological properties such as volume or viscosity.

In addition, the optical properties birefringence reflection and light transmission are changed. The difference in these changes can be easily determined and compared to other physical values in order to be able to identify the correct melting point by recording the percentage of light intensity shining through the sample in the capillary, the transmittance, in relation to the measured furnace temperature.
