Development Overview of Refractory Materials

In this paper, current situation of refractory industry in China is introduced briefly.Developing tendency of refractory materials is remarked based on the technical development of high temperature industries.Advanced refractory materials, characterized by long service life, functionalization, lightweight and ecological-friendly design, play very important roles in sustainable development of high temperature industries.Since the key service properties of advanced refractories constrain each other in traditional material design and fabrication, new design methods are developed to optimize the key service properties simultaneously.Combined with the development of new insulating materials, and functional refractories used in steel-making industry, structure-function combining design concept and new fabrication technologies are introduced by applying FEM analysis, bridging of advance ceramic technologies, and multilayered/gradient composite structure.
