Abstract

Effects of electron beam irradiation on an aluminophosphate microporous material, AlPO₄-5 with AFI type framework structure, and its damage processes under the electron beam accelerated by 300 kV were investigated. The successive series of the electron diffraction patterns taken along [001] direction from the same area of the specimen revealed that about 6 C/cm ² total dose on the sample enhances the vitrification of the AlPO₄-5 structure. HRTEM images after 2.5 C/cm² total dose already show that the electron beam damage partly becomes more apparent and generates the structural distortion.
