The crystals liquids can be defined like highly anisotropic fluid that exist between the crystalline solid phase and that liquid isotropa: this is that that has been defined the "fourth state of the matter".
The existence of these mesofasi is due to a sure organization that the molecules can assume passing from the former crystalline disposition of the solid state to the accidental disposition of the liquid state.
Numerous crystals liquids can be observe to you based on their optical birifrangenza to the microscope with polarizzatori filters intercross to you.
To the typical property of the solid state (optical anisotrophy and electrical worker) and of the liquid state (fluidity and molecular mobility) join to peculiar characteristics of crystals liquids: as an example the possibility to vary of the degree of order for means of magnetic fields and electrical workers, or the faculty that they have to change color varying of the temperature.
This has made of crystals composed liquids a class of that today they are widely used for the construction of objects of daily use.
