Solution route applying the precursor of metaldihydrogen phosphate dihydrate was used to synthesize M-cyclophosphatesat ambient temperature (cobalt (II) was selected as model for metal in these investigations). The precursor was fired and sintered at different temperatures (600, 800, 1000 and 1100°C) respectively to optimize best conditions to obtain Co2P4O12 crystal form with high purity. The products were monitored by both of XRD, IR spectra by additional to accurate imaging via scanning electron microscope (SEM) and AFM-microscopeto analyzesurface topology and microstructural features of the metal cyclotetraphosphate. Structural investigations via XRD proved that the product obtained at 1100°C is the best and fine structure with monoclinic structure phase and C12/C1 space group with lattice parameter a=11.809(2), b=8.293(1), c=9.923(2) A respectively. A visualized investigations were performed to confirm structure validity and stability at temperature of sintering (1100°C). Visualization studies indicated that variations of bond distances between Co1, Co2, P1 and P2 and different six oxygen atoms (O1, O2, O3, O4, O5 and O6) inside crystal lattice are responsible for increasing lattice flexibility factor (by controlling in shrinkage and expansion coefficient) and consequently increase its bonds stability to break.
