TABLE 124.— REVERSIBLE TRANSITIONS IN CRYSTALS* 



Values are given, for the more important crystals, of the inversion temperature in C C, 

 the heat of inversion in cal/g and the inversion volume change in cmVg. No monotropic 

 inversions have been included. 



hi, inversion temperature on heating; m, metastable inversion temperature; e, estimated; 

 g, gradual inversion (not to be confused with slow retarded inversions).
