BIOGRAPHY
Dr. Analía G. Tomba Martinez has experience in the field of ceramics, including refractories and advanced dense and porous materials, mainly regarding to their evaluation under near-service conditions. In particular, her investigations are oriented to mechanical and chemical behavior of ceramics at high temperature. More recently, the characterization of natural raw materials for ceramics products is also included in her research interests. She has published over 80 articles in the main scientific journals in the field of materials and ceramics, and supervised 15 undergraduate and graduate students of Materials Engineering and Materials Science, respectively. She is Principal Researcher of the National Council of Scientific and Technical Research in Argentina (CONICET), and carries out teaching activities at the University of Mar del Plata. During her career, she was involved in several transferences of knowledge to the private sector, mainly in relationships with the steelmaking industry.
PROJET
Improvement of methods to determine key properties related to the corrosion behavior of refractories
Refractory materials are key inputs in several industries and they represent a significant part of the production cost. Hence, the efforts of both industrial and academic sectors are geared towards obtaining better materials, with longer lifetimes, reducing also the environmental impact generated by their waste. Since corrosion is one of the processes that frequently limits the refractories lifetime, it is extremely important to control and minimise it, and then, it is necessary to know the mechanisms and determining factors of such phenomenon. For this reason, the search for more and better tools to study the corrosion process is always ongoing, and represents serious challenges to be solved.
The proposed project aims to contribute to the improvement of methods for determining key properties in the evolution of gas and liquid corrosion of refractory products. The knowledge of such properties is more useful in the comprehension of the phenomena which are they involved (gaseous and liquid corrosion in this case) as closer as the experimental conditions for the measurement are. The service conditions of such industrial materials generally involve high temperature and aggressive atmospheres, among others, which add complexity to the in-lab measurements and demand the need to solve challenging experimental issues. This is the main reason why the values of several refractory’s properties are only available at room temperature. As the contribution to revert this situation, this project proposes to develop in-lab methods to measure transport properties at high temperature, specifically, the intrinsic permeability and the capillary suction properties, which are not available in the present time.
