We analysed thermal (20°-1000°C) phase changes of the substrates of Zn3(PO4)3.2H2O (1) and Mg3(PO4)2.8H20 (7) and their binary mixtures (percentage ratio 10%-90%). Thermal differential analysis (TG, DTG, DTA), IR and XR, showed that the above mentioned substances, heated for 1 hour up to 500° and 1000°C changed the structure. Samples contain: 90%, 70%, 50% Zn3(PO4)3-2H2O (1) in the binary mixtures with Mg3(PO4)2.8H2O (7) change the structure at 500°C into Zn3(PO4)2 and at 1000°C in (ZnMg)3(PO4)2, other binary mixture (30%, 10%) have structure Mg3(PO4)2 (at 1000°C).
