Abstract

La presente invención se refiere a un procedimient mejorado para producir beta-dioxido de manganeso, caracterizado porque comprende alimentar a una cámara gamma-dióxido de manganeso consituído por partículas, cambiar contínuamente las posiciones relativas de las partículas de Mn0(2) en dicha cámara mientras que se caliente el gamma-dióxido de manganeso al menos a 450 grados C, mantener la temperatura del dióxido de manganeso al menos a 450 grados C durante un tiempo para convertir una mayor parte del dióxido de manganeso en una fase cristalina beta, sin formar cantidades perjudiciales de óxidos inferiores, y retirar el dióxido de manganeso tratado térmicamente de la cámara.The present invention relates to an improved process for producing manganese beta-dioxide, characterized in that it comprises feeding a chamber gamma-manganese dioxide constituted by particles, continuously changing the relative positions of the Mn0 (2) particles in said chamber while the manganese gamma-dioxide is heated to at least 450 degrees C, maintaining the temperature of the manganese dioxide at least 450 degrees C for a time to convert a greater part of the manganese dioxide into a beta crystalline phase, without forming amounts harmful to lower oxides, and remove heat-treated manganese dioxide from the chamber.
