Abstract

La présente invention se rapporte à un matériau fritté à base de platine qui est utile en tant que matériau décoratif, caractérisé par le fait qu'il est produit en soumettant une poudre mélangée, obtenue par mélange d'une quantité comprise entre 50 et 99,9 % en masse d'une poudre de platine qui présente un diamètre particulaire compris entre 1 et 300 μm avec une quantité comprise entre 0,1 et 50 % en masse d'une poudre noire de platine qui présente un diamètre particulaire compris entre 1 et 300 μm, à un moulage et un frittage. Ce matériau fritté à base de platine peut se passer d'un post-traitement pour donner un éclat nécessaire aux bijoux.
