Sur les modifications subies par quelques phosphates acides à la suite d'une compression ou d'une déformation mécanique

The author subjected several acid phosphates to high pressures in a specially constructed cylinder with the following results: Ca(H2PO4)2H2O loses first its water of crystallization and finally a portion of the phosphoric acid, these two constituents being forced out of the compression cylinder. In general those constituents which were capable of liquefying under the pressure were found to be eliminated most readily. The acid phosphates of calcium, sodium and probably lithium form molecular compounds with their respective sulphates, that of calcium being insoluble in water and probably constituting one of the causes of reversion.
