This research article critically analyses the difference and change in the structural complex of FEPO4 throughout its change in its temperature range, from 294K to 1073K in this case. We have also noticed that FePO4 is very different from many other alpha-quartz isotypes, one example being the SiO2, as the A cation is a kind of transition metal. This experiment was carried out to further bring out observations of FEPO4 in the alpha phase, which is when FEPO4 is at 980K. At the point of the first order transition, the exact distance between the Fe-O in its tetrahedral form was noted to have an inverse relationship when its exact temperature, thus having an uncanny similarity to the behaviour that was observed in the SI-O distances in alpha-quartz. …show more content…

The Quartz crystal structure that make use of the similar convention with other forms of structure were owed to the fact that Fe sites are coordinated by the 6 linked nearest O atoms in an approximate octahedral geometry for the olivine and the CrVO4 structures. As for the quartz structure, we can see that the Fe sites are coordinated by 4 nearest O atoms once again in an approximate tetrahedral geometrical fashion. In contrast, for the monoclinic structure of FEPO4, the Fe sites would possess a lower symmetry while their coordination with each neighbouring O would only be 5. Last but not least, I would discuss the mechanism of the symmetry change for the FePO4 kind of polymorphs. The specific neat quartz arrangement of the FEPO4 compound is also made up of FeO4 and PO4 tetrahedrons. This kind of quartz type iron phosphate, FEPO4, was also observed in the neutron precipitate diffraction at the temperature range of 294K-1073K. This particular refined somatic constraints of the low temperature alpha phase would tend and lean towards the values that were obtained for high temperature beta quartz kind of FEPO4. To add on, the non-structural kind of activities would also stem from the increasing abnormalities with increasing temperature due to the increasing excitement due to temperature change. This would also further culminate in high amplitude kind of vibration in the alpha quartz. This particular outcome from this condition would result in a quartered total neutron scattering structure. The tetrahedrons’ distortion is defined as the time when the angles and bond lengths are varying altered. On the other hand, this differs with tetrahedron tilting, since tilting is the time where only the bond angles are different. The Fe-O-P angles would also enlarge and tilt when the temperature has risen above 500 degrees Celsius. Alpha-beta
