From infrared and thermogravimetric studies, Pechkovskii et al. [836] identify the following steps in the decomposition of Mg(H2P04)2 2 H20. 

The reaction of Ca(H2P04)2 H20 is even more complicated [836], involving the formation of Ca2P207 and Cas(P3O10)2. Anhydrous CaHP04 (monetite) decomposes [837] to 7-Ca2P207 ( 770 K,E = 213 kJ mole-1) and is transformed to the -modification at higher temperatures.
