Question

how amorphous solid can be converted into crystalline solid. plz reply soon .if anyone else . who answeres my question first i selected him as a brainliest answer

Answer 1

The simplest method is to convert it by heating it till its melting point and then quickly cool it down rapidly (With liquid N2). This will prevent recrystallization, Any future heating past its crystallization temperature will of course lead to recrystallization.

Answer 2

Yes, amorphous solids can be converted into crystalline solids depending on some conditions.


Thus, to convert an amorphous solid material into a crystalline material, I suggest to melt or dissolve it in an appropriate solvent. Then, solidify the material from the melt through very slowly cooling down so that the molecules (or macromolecules in the case of polymers) of the material find sufficient time and opportunity to arrange an ordered crystalline microstructure. For material dilute solution, very slowly evaporate the solvent, the remaining solid will likely show crystalline order if chemical structure of the material has the talent. The other strategy is using a supersaturated solution of the material. It is possible to produce crystals of material through insertion of an appropriate body in the supersaturated solution. In this case, the crystals are formed on the surface of that inserted body because of surface phenomenon created by that body. The microstructure of material can be detected and examined with analytical techniques, like X-ray diffraction and scattering to see if the experiment was successful.
