Ceramics are one of the earliest synthetic materials in human civilization, which is originated in China. They represent not only the nation's glory but also the testament to the wisdom and innovation of her people. After millennia, ceramics have evolved into a vital material system encompassing both traditional and advanced varieties, with structural ceramics holding a key position. Their high-temperature resistance, corrosion resistance, and superior mechanical properties endow them indispensable in harsh environments where metals and polymers are still in struggle, underscoring their role as a cornerstone of modern technological progress. Ceramic matrix composites have mitigated the brittleness of structural ceramics, garnering global attention for their irreplaceable advantages, particularly in extreme conditions like ultra-high temperatures, intense radiation, and severe corrosion, across sectors such as aerospace, transportation, and advanced nuclear energy.Despite peaking in the 1980s with innovations like ceramic engines and high-performance cutting tools, the development of structural ceramics encountered a slump due to limitations in fabrication techniques and reduced industrial demand. Nevertheless, persistent research efforts have led to significant advancements, broadening application scope of these materials.Invited by Journal of Inorganic Materials, we have curated the special issue of “Frontiers of Structural Ceramics” featuring contributions from eminent domestic research groups, including Northwestern Polytechnical University, Wuhan University of Technology, Harbin Institute of Technology, Nanjing University of Aeronautics and Astronautics, Beihang University, National University of Defense Technology, Jilin University, Northeastern University, Zhengzhou University, Chang’an University, Institute of Metal Research, Chinese Academy of Sciences, and Shanghai Institute of Ceramics, Chinese Academy of Sciences, etc. The special issue is delving into the design, preparation, simulation, performance evaluation, and exploration for damage mechanisms of new structural ceramics.We aim for this publication to deepen researchers’ insights into structural ceramics, provide a platform for exploring recent advancements, and foster the progression of the field. We extend our heartfelt gratitude to the experts who contributed despite their busy schedules, acknowledging their dedication and support that made this publication possible.
