Abstract
La présente invention concerne un corps moulé en sulfure de zinc ayant un rapport sulfure/zinc proche de 1 ou un sulfure composite contenant du sulfure de zinc et au moins un élément choisi parmi l'argent, le cuivre, le manganèse et des éléments de terre rare, ledit corps moulé étant obtenu par un procédé commercial simple. L'invention concerne également un procédé de production d'un tel corps moulé. De manière spécifique, l'invention concerne un corps moulé en sulfure de zinc ayant un rapport sulfure/zinc égal ou supérieur à 0,9 ou un sulfure composite contenant du sulfure de zinc et au moins un élément choisi parmi l'argent, le cuivre, le manganèse et des éléments de terre rare. L'invention concerne en outre un procédé de production d'un tel corps moulé.
