Abstract
Series of diffraction patterns were measured with dry powdered ammonium nitrate from 50 – 60°C on heating and from 50 – 40°C on cooling. The variation of lattice constants allows to observe the transition. On heating the phase transition IV/II occurs between 52 and 56°C. In this temperature interval both phases are existent. On cooling, simultaneous transitions II/IV and II/V occur with phase V slowly transforming into phase IV.Keywords
