Embodiment 1
[0027] Magneto-optic crystal Gd with high cerium content and scandium-doped gadolinium iron garnet 2.60 Ce 0.36 Ca 0.04 sc 0.96 Fe 4.03 V 0.01 o 12 And preparation method thereof, concrete steps are as follows:
[0028] (1) Synthesis of polycrystalline raw materials: Weigh high-purity Gd according to the stoichiometric ratio 2 o 3 , Fe 2 o 3 Drugs, after being ground and mixed evenly, pressed into tablets, pre-sintered at 800°C for 10 hours, then sintered at 1300°C for 10 hours, after taking out, ground and pressed tablets, and then sintered at 1300°C for 10 hours to obtain Gd 3 Fe 5 o 12 polycrystalline material. The stoichiometric ratio of CeO 2 , NH 4 VO 3 The powder was mixed evenly, pressed into tablets, and then heated and sintered. During sintering, the temperature was kept at 200°C, 400°C, 670°C and 800°C for 2 hours respectively to obtain CeVO 4 polycrystalline powder. The stoichiometric CaCO 3 , Fe 2 o 3 The powder is pre-sintered at 900°C for 10h...
