Scattering Particles in Lead Fluoride Crystals
|
Abstract:
Based on the observation with optical microscope and analysis by EDS of electron microprobe and scan electron microscope, the scattering particles existing in lead fluoride crystals were firstly confirmed to be lead metal Their shapes are characterized by gradually evolving from irregrlar shape to diamond shape There is a face which direction is always parallel to the (100) face of PbF 2 crystal It was suggested that the scattering particles are formed from the following process: reduction of lead metal, inclusion of melt, nucleation and solidification along some dection of PbF 2 crystal
