Résumé
La structure de verres Pb O - Pb Cl2 a été étudiée par diffraction neutronique, en fonction de la composition entre Pb O - Pb Cl2 et 9Pb O - Pb Cl2. Alors que la première distance Pb - O est bien définie, la distribution des distances Pb - Cl est beaucoup plus large, en accord avec les mesures d'EXAFS antérieures.
Abstract
Neutron diffraction techniques have been employed to investigate the structure of PbO-PbCl2 glasses as a function of composition in the nominal range PbO.PbCl2 to 9PbO.PbCl2. It is concluded that, whereas the first Pb-O distance is well defined, the distribution of Pb-Cl distances is much broader, in agreement with a previous EXAFS study.
