Abstract
La presente invención se refiere a un método para elaborar un objeto que comprende nitruro de silicio densificado, mediante las etapas de: a) configurar una mezcla en polvo substancialmente homogénea de nitruro de silicio y oxinitruro de silicio de itrio, el último estando presente en una cantidad suficiente para formar una solución viscosa con cuando menos una porción del nitruro de silicio durante el calentamiento de fusión, la configuración siendo llevada a cabo para formar un objeto de menos de la dimensión y densidad requeridas; y b) densificar el cuerpo configurado mediante fusión térmica, con o sin el uso de presión mecánica, para constituir un objeto de la densidad y dimensión requeridas.The present invention relates to a method of making an object comprising densified silicon nitride, by the steps of: a) configuring a substantially homogeneous powder mixture of silicon nitride and yttrium silicon oxynitride, the latter being present in a sufficient quantity to form a viscous solution with at least a portion of the silicon nitride during fusion heating, the configuration being carried out to form an object of less than the required size and density; and b) densifying the configured body by thermal fusion, with or without the use of mechanical pressure, to constitute an object of the required density and dimension.
