Large‐scale synthesis of ytterbium silicate (Yb 2 SiO 5 ) nanoparticles and nanorods has been realized by a facile molten‐salt approach. The synthesized products were structurally and morphologically characterized by X‐ray diffraction, transmission electron microscopy (TEM), and high‐resolution TEM. Our results revealed that the morphologies of Yb 2 SiO 5 products can be readily controlled by a simple variation of the reactants used for the molten‐salt reaction. Single‐crystalline Yb 2 SiO 5 nanorods with a high yield can be obtained using NP‐7.5 as a surfactant. The formation mechanism of Yb 2 SiO 5 nanostructures was also discussed. The method presented here for the synthesis of Yb 2 SiO 5 nanostructures may pave the way for their application as environmental barrier coating materials.
