主 题:A2B2O7 system transparent ceramics powder synthesis sintering potential applications
摘 要:A_2B_2O_7 system compounds, which usually present three phase structures mainly based on the ionic radius ratios of r_A and r_B(r_A/r_B), have been studied for potential applications in many fields, such as thermal barrier coatings, luminescence powders, fast-ion conductors, photocatalysts, and matrices for immobilization of highly active radionuclides. Since 2005, La_2Hf_2O_7 was fabricated into transparent ceramics and much more attentions were paid on A_2B_2O_7 transparent ceramics for new applications. In this review, the development of A_2B_2O_7 system transparent ceramics was described. The structure characteristics, powder synthesis method, and sintering techniques of the final A_2B_2O_7 transparent ceramics were summarized. After that, the mostly reported A_2Hf_2O_7, A_2Zr_2O_7, and A_2Ti_2O_7 system transparent ceramics were systematically introduced. The potential application fields and future development trends were also discussed, focusing on scintillators, optical elements, and other luminescent materials.
