Tetragonal to cubic phase transition in silver chlorate
- 34 Downloads
Silver chlorate crystallizes in the tetragonal system at room temperature. The crystal undergoes a reversible first order phase tronsition to a cubic phase at 139°C. The transition temperature along with the enthalpy change was determined by thedsc technique and the change of enthalpy was found to be 3·12 cal/g. The high temperature form as determined by x-ray powder diffractometric method was found to be primitive cubic with a lattice constant of 6·681 Å at 145°C.
