Diffuse Phase

Molecular relaxation processes in lithium carbonate (Li2CO3), sodium carbonate (Na2CO3) and potassium carbonate (K2CO3) were studied by Raman spectroscopy. It has been established that in crystalline carbonates Li2CO3, Na2CO3 and K2CO3, the structural phase transition of the first kind is stretched (diffuse phase transition). The existence of the pretransition region in the studied carbonates Li2CO3, Na2CO3 and K2CO3 was found.
