Swift heavy ion irradiation of titanium phosphate and related materials

Amorphous and crystalline (both, α- and γ-forms) titanium phosphate, titanium molybdate and tungstate were irradiated with swift heavy ions of 84Kr and 203Bi at a fluence of 5×1010-1014 ion cm−2. The crystalline structure of the materials was characterized by XRD method before and after irradiation. Comparison of the powder diffraction patterns revealed that the irradiation had practically no effect on the materials with the exception of γ-crystalline structure. This structure was destroyed under the effect of radiation of 84Kr ions and became amorphous above the fluence of 1×1012 ion cm−2. In case of irradiation with 203Bi ions it became amorphous at the lowest fluences applied.
