Abstract
The ionic conductivity of the calcium hydrogenphosphate dihydrate CaHP O4, 2H(2)O, brushite, in powder state is due to the protons, coming fr om the adsorbed and from the lattice water molecules. Infrared spectro scopy, thermogravimetric analysis, controlled transformation rate ther mal analysis and electrochemical measurements as a function of tempera ture and humidity are reported on polycrystalline pellets of this phos phate. Characteristic potential difference values, using a disk of bru shite as a solid electrolyte, are shown to vary during heating.
