Quartz ceramics have many excellent properties such as high temperature resistance, low coefficient of thermal expansion, low dielectric constant, and good high-temperature stability, and are widely used in industries such as glass manufacturing, solar photovoltaic, and steel metallurgy. In particular, as the main material of radome, antenna window and nozzle for aircraft, it has important applications in the aerospace field. However, as a brittle material, the low fracture toughness of quartz ceramics seriously restricts its development. Therefore, the toughening technology of quartz ceramics has become a research hotspot in this field. This article mainly introduces the methods and toughening mechanisms of particle dispersion toughening, fiber toughening, and composite toughening of quartz ceramics, and focused on summarizing the current problems, exploring the development direction of quartz ceramic toughening technology.
