Abstract Silicon nitride ceramics comprehensively have excellent properties such as high strength, high elastic
modulus, high-temperature resistance, thermal shock resistance, and low dielectric constant. They are the major
candidate materials for high-temperature wave transmitting radome. Currently, research in silicon nitride-based
ceramics and composites is popular. This paper has reviewed the research status of silicon nitride ceramics, SiALON
ceramics, silicon oxynitride ceramics, nitrogen oxide ceramics, and their composite materials in the past five years.
Through the combination of material design and different molding processes, including 3D printing, chemical vapor
infiltration (CVI), and precursor impregnation cracking (PIP), the preparation of high-strength-low dielectric silicon
nitride-based ceramic materials was acquired, which enables the selection of materials and design support for wavetransparent
components of high-Mach vehicles.
