Swift heavy ion and gamma-ray irradiation of various double metal phosphates

The first-row transition metal salts of zirconium-, titanium-, and hafnium phosphates, respectively were irradiated at various doses with swift heavy ions of 240 MeV 84Kr and 720 MeV 203Bi and with gamma-rays of 60Co at dose of 3×106 Gy. Comparison of powder diffraction patterns of non-irradiated and irradiated samples reveals that the irradiation with gamma-rays has no effect on the materials. Irradiation with swift heavy ions of 84Kr and 203Bi at higher dose caused some degradation of the structure of titanium and hafnium double metal phosphates. The electrical conductivity value of the irradiated samples remained inside the order of magnitude characteristic for untreated materials.
