Abstract
La presente invención se refiere a un metodo para elaborar oxinitruros de silico de itrio, de conformidad con la fórmula YaSibOcNd, mediante las etapas que comprenden: a) mezclar juntas, en contacto reactivo íntimo, cantidades estequiometricas de Y2O3, SiO2 y Si3N4 para formar un oxinitruro de silicio de itrio deseado, en donde a, b c y d representan las partes requeridas de elemento del compuesto en equilibrio con las partes de elemento de mezcla, el SiO2 puede estar presente como un revestimiento de óxido sobre el Si3N4; b) calentar la mezcla en una atmósfera inerte hasta un nivel de temperatura y durnate un tiempo suficientes para convertir las cantidades estequiometricas de la mezcla en el oxinitruro de silicio de itrio deseado; y c) molar la mezcla aglomerada termicamente hasta un polvo.The present invention relates to a method for preparing yttrium silicon oxynitrides, in accordance with the formula YaSibOcNd, by the steps comprising: a) mixing together, in intimate reactive contact, stoichiometric amounts of Y2O3, SiO2 and Si3N4 to form a Desired yttrium silicon oxynitride, where a, b and d represent the required element parts of the compound in equilibrium with the mixture element parts, the SiO2 may be present as an oxide coating on the Si3N4; b) heating the mixture in an inert atmosphere to a temperature level and lasting sufficient time to convert the stoichiometric amounts of the mixture to the desired yttrium silicon oxynitride; and c) grinding the thermally bonded mixture to a powder.
