Abstract:
Scheelite structure phase inorganic oxides show their irreplaceable role in numerous application areas due to their clear structure and superior properties, especially in dielectrics. Scheelite structure phase BiVO 4 has been permanently studied but substitutions, modifications, and explorations of novel phases persist hitherto and inspire more interest. In this work, we report a novel Scheelite structure phase of Bi(Ge 0.5 Mo 0.5 )O 4 and a detailed study of both structural analysis and dielectric properties investigation. Bi(Ge 0.5 Mo 0.5 )O 4 adopts the monoclinic Scheelite structure, identical to BiVO 4 , with a dielectric permittivity of ∼ 35, Q f value of ∼20 000 GHz, and TCF value of ‒46 ppm/°C. No secondary ferroelastic transition was seen in Bi(Ge 0.5 Mo 0.5 )O 4 till 600°C, close to its synthetical temperature. The results indicate the success of discovering a new Scheelite structure phase and its prior engineering potential in modifying and substituting BiVO 4 over the dielectric area, photocatalyst, ion conductor, and so forth.
