Lead phosphate glasses have been investigated for decades with respect to fundamental glass properties such as glass transition, devitrification, electrical and optical properties. In these glasses, [PO4] tetrahedra, (like [SiO4] tetrahedra in silicates) can link up together by corner sharing oxygen atoms to form polymerized structures upto and including three dimensional glassy networks. Although, little electron diffraction data on amorphous phosphates is available, radial distribution functions have been generated for lime phosphate glasses and amorphous aluminum phosphates using x-ray diffraction techniques. More recently, Sales et al. have examined near surfaces of single crystals of lead pyrophosphate (Pb2P2O7), rendered aperiodic (metamict) by ion implantation, and lead pyrophosphate glass using high-performance liquid chromatography (HPLC), making use of the fact that condensed phosphates do not alter their state of polymerization when dissolved in aqueous solutions.In our studies, single crystals of Pb2P2O7 were found to be beam stable under 200 keV TEM electrons to an electron fluence > 1027 e/m2 and an ionizing dose > 1014 Gy. This negative radiolytic result leaves ballistic displacement by ions or neutrons as the only route to render the samples metamict.
