Neutron-diffraction studies on liquid, glassy, and crystalline Ca0.4K0.6(NO3)1.4

The temperature dependence of neutron diffraction by Ca 0.4 K 0.6 (NO 3 ) 1.4 , in the liquid and glassy states, was measured together with the time dependence of the transformation to the crystalline states. The measurements were performed over the range of Q from 0.2 to 5.5 Å −1 (1 Å = 10 −10 m) for temperatures between 300 and 573 K. On cooling, a glass was formed with a glass transition temperature of T g = 335 K; on heating, two …
