Red ceramics are part of one of the sectors of ceramic materials that make up the formation of the civil construction complex. In Cariri region and in the rest of Brazil, this segment uses clay as the main source of raw material, which favors the appearance of micro, small and medium enterprises that produce most of the products manufactured by the red ceramic sector. The objective of this work was the mineralogical and technological characterization of a clay sample from one of the potteries in Cariri region, intended for the manufacture of products to be used in civil construction such as tiles and bricks. For that, the techniques of X-ray fluorescence and X-ray diffraction were used, in addition to determining the physical-mechanical properties of the specimens by 4 ton-force uniaxial pressing followed by firing at 800, 900 and 1000ºC. The results showed that the sample is composed of quartz, kaolinite, smectite and muscovite and that it has granulometry mostly in fine fractions; after firing the clay shows reddish color and the Atterberg limits are within the range indicated for use on red ceramics. The clay under study has technological properties suitable for manufacture and the specimens burned at 800°C do not meet the values indicated by the literature. The studied clay proved to be suitable for application in tiles and perforated bricks.

Materials Engineering presents an important process in the development of new technologies, in the creation and improvement of materials, aimed at improving aspects of society, such as: health, safety, quality and well-being of human life. Being ethics is an intrinsic factor to life in which it is possible to affirm that the exercise exerts the capacity to think in actions and conducts that can be used as exercises of any type of activity. technical and human resources. Aligned in this context, the present work aims to trigger on the ethics in the training and the performance of materials engineers based on a bibliographical review. During the review process, the ethics-related study topics were highlighted, which are of great relevance for postgraduate studies in life sciences; since the experience is a part of the professional is increasingly progressing its presentation devices that are beyond technical training. Based on the article of literature over time, this is a work that can be applied to a professional in the area of communication, such as the applications of technical norms required in the exercise of the profession in a way associated with moral, legal, environmental and humanitarian concepts. Finally, it was possible to verify that it was indispensable for the professional tasks of the engineering of materials or for the formation of other activities similar to the plan and the use of concepts and concepts specific to the social sciences, as is the case of ethical issues, with focus in explaining the code of professional ethics in order to meet a challenge as the demands demanded by the increasingly pluralized and multicultural world does not qualify at the present time.
