Synthesis of Me Doped Mg(OH)(2) Materials for Thermochemical Heat Storage

In order to investigate the influence of metal (Me) doping in Mg(OH)(2) synthesis on its thermochemical behavior, Ca(2+), Co(2+) and Ni(2+) ions were inserted in Mg(OH)(2) matrix and the resulting materials were investigated for structural, morphological and thermochemical characterization. The dens...

Sumario:In order to investigate the influence of metal (Me) doping in Mg(OH)(2) synthesis on its thermochemical behavior, Ca(2+), Co(2+) and Ni(2+) ions were inserted in Mg(OH)(2) matrix and the resulting materials were investigated for structural, morphological and thermochemical characterization. The densification of the material accompanied by the loss in porosity significantly influenced the hydration process, diminishing the conversion percentage and the kinetics. On the other hand, it increased the volumetric stored/released heat capacity (between 400 and 725 MJ/m(3)), reaching almost three times the un-doped Mg(OH)(2) value.
