Structural transition study of NiCl2.2H2O by specific heat
- 1. Universidade Estadual de Londrina, PR (Brazil). Dept. de Fisica
Description
The specific heat of polycrystalline NiCl2.2H2O measured in an adiabatic calorimeter by the heat-pulse method between 80 and 281 K indicates a first-order phase transition at Tc = (220.0 ± 0.5) K. This confirms a crystallographic transformation first detected by X-ray and EPR methods. (author)
