采用熔盐法和固相法合成了Dy2TiO5粉体。分析了熔融介质对合金相组成和显微组织的影响。熔盐的加入显著降低了合成温度，并导致均匀的粉末。在1600 °C下无压烧结由所制备的粉末压制的绿色体。研究了烧结芯块的烧结性能、力学性能和中子吸收性能。结果表明，熔盐法合成的材料具有较高的断裂韧性和抗弯强度，优异的硬度和中子吸收性能。对于8cm厚的芯块，中子吸收率达到86.6%。
Dy2TiO5powders were synthesized by molten salt and solid-state methods. The influences of molten medium on phase compositions and microstructures were analyzed. The addition of molten salt lowered significantly the synthesis temperature and resulted in uniform powders. Green bodies compacted from the prepared powders were pressureless sintered at 1600 °C. Sinterability, mechanical properties and neutron absorption performance of the sintered pellets were studied. Results showed that molten salt synthesis resulted in materials with higher fracture toughness and bending strength, excellent hardness and neutron adsorption performance compared to the solid-state process. The neutron absorption rate reached 86.6% for 8 cm thick pellets.
