Abstract A series of alkaline earth metal orthophosphates M 3 (PO 4 ) 2 · X H 2 O (M = Mg, Ca, Sr and Ba) is studied by DTA, TG and DTG techniques followed by X-ray diffraction and IR spectroscopy. The activation energies for the dehydration of the various phosphates are evaluated, and the structural changes occurring in the phosphates on calcination at different temperatures are discussed in the light
