Corrosion Failures of Industrial Refractories and Technical Ceramics

This article provides a discussion on the corrosion of industrial refractory materials and technical ceramics. These materials, which are used to minimize heat losses and provide a barrier between the vessel and its contents, are utilized in the metallurgical, chemical process, power generation, automotive, and aerospace industries. The article covers the fundamental principles of chemical corrosion of refractories and ceramics, and the use of thermodynamic calculations and kinetic models to evaluate the probability of the occurrence of corrosion-causing chemical reactions. It describes the corrosion resistance characteristics of specific classes of refractories and structural ceramics. The article also examines the prevention strategies that minimize corrosion failures of both classes of materials.
