| Abstract: | The development history of magnesium aluminate spinel transparent ceramics was reviewed and the relationship between its structure and properties was summarized in this paper. Based on optics theory, the factors influenced the transmittance of ceramics were elucidated, including porosity and impurity. To synthesize the magnesium aluminate spinel with high transmittance, it is fundamental to develop the high quality powder, improve the sintering densification of green body, and optimize the surface processing technology to meet the demand of national defense and other fields. |
