Abstract
L'invention a pour but de remplacer le monocristal de Bi12 SiO20 par un matériau polycristallin susceptible d'être synthétisé sous la forme de pièces de grandes dimensions tout en présentant une bonne << photosensibilité >> aux rayons X. Le matériau suivant l'invention est fabriqué à partir d'un mélange de poudres d'oxydes de bismuth et de silicium très purs, par des traitements de broyage en milieu aqueux, chamottage à 700 degrés C mise en forme sous pression, et frittage en atmosphère oxydante à 700 degrés C sous une pression de 0,5 t/cm**2. Application la visualisation d'images en rayons X.
