- Product Prediction: Intermediates Formed During Rare Earth Reactions Rodrigo Castañeda Elizabeth Chavira Oscar Peralta Multidisciplinaria (Ciencias Naturales y Exactas) TG XRD DSC Rare earth Thermal analyses, X-ray diffraction (XRD), and HR-XRD (High Resolution XRD) were used to identify thermal behavior products in a family of solid-state reactions involving rare earth (REE) reagents. REE where sorted in light and heavy groups. The general reactions under study were: REE2O3 + Fe2O3 + As2O3 → 2REEFeO3 + As2O3↑ and 2REE(OH)3 + Fe2O3 + As2O3 → 2REEFeO3 + As2O3↑ + 3H2O↑, REE= La, Ce, Nd, Sm, Gd, Dy, Ho, Er, and Yb. Based on the experimental results, it is possible to predict the different compounds of REE products in a series of reactions analyzing only three of the reactions, two for light REE and one for heavy REE. 2014 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47531165012 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.1 Vol.58
