Wide Angle Scattering During Crystallization and Solid State Phase Transitions

5 Wide Angle Scattering During Crystallization and Solid State Phase Transitions 

The kinetics of crystallization is usually measured dilatometrically. However, investigations by wide angle scattering, which became possible by using synchrotron radiation, have the following advantages  

If the material crystallizes in different crystal modifications one also gets the information which kind of the different modification is formed. 

One can also measure the kinetics of the crystallization of oriented materials, which is not possible in a dilatometer because there is no way to apply stress to the samples. In addition, by the X-ray wide angle scattering one obtains information on the degree of orientation. 

One determines not only an overall crystallinity as by density but one obtains also information on changes in crystal imperfections and crystal sizes.
