The design of undergraduate laboratory sessions that provide meaningful research-based experiences enhances undergraduate curricula and prepares future graduate students for research careers. Solid State Chemistry has attracted the attention of many fields due to its wealthy chemistry as well as the versatility of its applications. Among the wide fields in this area, the study of an inorganic ceramic pigment has been selected in this experience. A ceramic pigment can be defined as a colored inorganic solid, black, white or fluorescent, normally insoluble and practically unaffected neither chemically or physically by the vehicle or substrate in which it is incorporated. From a structural point of view, a ceramic pigment is formed by a host network where the chromophore component, usually transition ions, generates the color without producing a change in the structure. A suitable host network must have, in addition to a high chemical resistance against oxidation and reduction and a high melting point, energy differences between favorable bands to allow the chromophore to produce colors in the region of the visible spectrum. A teaching strategy has been proposed for undergraduate chemistry students, introducing them to the solid-solid reaction by the synthesis of a pink ceramic pigment based on chromium doped ZnAl2O4 with spinel structure. The as-prepared pigment has been characterized by two different techniques, such as X-Ray Diffraction and UV-Vis spectroscopy, commonly used in Solid-State Chemistry. In this way, students will have a first approach to the basic concepts of the Solid-State Chemistry through simple laboratory sessions. Due to the simplicity and easy strategy used in this study, the students will be able to participate actively, fulfilling the pedagogical character demanded by a Problem Based Learning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
