Abstract
Radiation effects in complex ceramic materials, including the crystalline phases with the apatite structure are of interest to the materials science, geoscience and biomedical communities. It has been shown by in situ TEM experiments that these materials can easily be rendered amorphous under heavy ion irradiations. Detailed study at atomic level using HRTEM on this crystalline to aperiodic transition is necessary for the fundamental understanding of the process. The results reported below are from a systematic HRTEM study on 1.5 MeV Kr ion irradiated synthetic Ca2La8(SiO4)6O2.The TEM samples were prepared from (0001) thin foils by Ar ion-milling which was finished at 3.5 kV and 13°. As shown in fig. 1, the width of the amorphous rim at the sample edge after ion milling is less than 2 nanometers. The pre-thinned TEM samples were irradiated at room temperature with 1.5 MeV Kr ions in the HVEM-Tandem Facility at Argonne National Laboratory.
