Abstract

Des poudres de phosphore et un procédé de fabrication de poudres de phosphore. Les poudres de phosphore ont des particules de petite taille, une distribution étroite de particules et ces particules sont substantiellement sphériques. Le procédé de l'invention permet avantageusement la production économique de telles poudres. L'invention porte également sur des dispositifs améliorés, comme des dispositifs d'affichage, intégrant les poudres de phosphore.
