[ES] La producción de los bronces metálicos del platino requiere de procedimientos químicos costosos que conducen a la producción de cantidades reducidas de estos compuestos y mezclas. La actual invención proporciona una lámina con recubrimiento de bronce metálico de platino y método para sintetizar estos compuestos, así como, para depositar estas mezclas en superficies grandes en forma de recubrimiento con un alto grado de especificidad, siendo este un factor determinante en aplicaciones concretas. El modo de obtención de los recubrimientos consiste en la reducción térmica parcial del dióxido de platino en atmósfera libre, acompañado de una difusión de los iones de sodio desde el substrato, ello permite el control de los componentes finales del recubrimiento. Este material se puede utilizar como catalizador de hidrogenación y como electrodo.
[EN] The production of platinum metallic bronzes requires costly chemical processes that give rise to the production of small amounts of such compounds and mixtures. The present invention provides a sheet with platinum metallic bronze coating and a method for synthesizing said compounds and also for depositing said mixtures on large surfaces in the form of a coating with a high leve1 of specificity, this being a decisive factor in specific applications. The way in which the coatings are produced comprises partial thermal reduction of platinum dioxide in a free atmosphere accompanied by diffusion of sodium ions from the substrate, which allows control of the final components of the coating. This material may be used as hydrogenation catalyst and as electrode.
