摘要：
Magnesium aluminum spinel transparent ceramics have the advantages of high transmittance, high strength, high thermal conductivity, resistance to environmental erosion and low dielectric constant, etc. It can be widely used in the military and civilian fields such as transparent armor, infrared window, substrate and so on. After more than 50 years of research, spinel transparent ceramics have developed a mature preparation process (powder-forming-sintering), which heavily relies on the commercial spinel powder with high purity and high activity. In this paper, the development of spinel transparent ceramics at home and abroad was briefly introduced and the work of the preparation of spinel transparent ceramics by reactive sintering by our team was focused on. The effects of raw powder crystal type, composition, sintering process and sintering additives on the microstructure evolution and properties of the material were analyzed, which can provide theoretical guidance for the optimization of material properties. In order to push forward the development of the manufacture process and application of spinel transparent ceramic, the relevant for different application fields was introduced for the first time, i.e. large-sized plate and hyper-hemispherical dome. © 2024 Chemical Industry Press Co., Ltd..
