Abstract

L'invention concerne des poudres de phosphore et un procédé de fabrication de poudres de phosphore. Les poudres de phosphore présentent de petites dimensions de particules, une répartition granulométrique serrée et sont sensiblement sphériques. Le procédé de l'invention permet avantageusement de produire ces poudres de façon économique. L'invention a également trait à des dispositifs améliorés, tels des dispositifs d'affichage, qui incorporent les poudres de phosphore.
