Abstract:
Silicon carbide (SiC) is a ceramic material characterized by highly covalent bonds between silicon and carbon, which give it unique properties such as high hardness, excellent resistance to oxidation, wear, corrosion, and abrasion, as well as high thermal conductivity, low thermal expansion coefficient, and good thermal shock resistance1. Due to its high stability and performance at extreme temperatures, SiC has been widely applied in the production of refractories for several sectors, mainly metallurgy2, with its first recorded use in refractory bricks for blast furnace torpedo cars3. Currently, it is found in various refractories used in mining and metallurgical equipment, such as torpedo cars, steel ladles, and hot metal pre-treatment vessels4. Refractory applications may require different mechanical and thermal demands depending on the process, region, and type of stress involved. Therefore, the selection of each refractory must be adapted to the process in order to maximize equipment service life, considering factors such as mechanical wear, chemical compatibility with metal, slag and process gases, as well as internal thermomechanical stresses from heating and cooling cycles5. In this context, this study aims to review the main applications of SiC in refractories, discussing its physical and chemical properties, as well as approaches that promote more sustainable processes and the benefits of its use, such as cost reduction, process optimization, lower consumption of primary raw materials, and mitigation of environmental impacts.
