We present a first principles study of the elastic, anisotropic mechanical, electronic, and optical properties of the newly synthesized double perovskite Na2ZrTeO6 compound. The calculated elastic constants confirm the mechanical stability of the compound. Na2ZrTeO6 exhibits high mechanical durability, a wide band gap, and significant anisotropic mechanical properties. The observed anisotropy suggests that Na2ZrTeO6 may exhibit direction-dependent mechanical and electronic behavior, making it a versatile material for advanced technological applications. The high Debye and melting temperature indicate that Na2ZrTeO6 may be very suitable for high-temperature processes, refractory materials, and high-temperature equipment. This compound is a semiconductor with a wide band gap and the electrons are mobile carriers because they have smaller effective masses. The optical properties, including the real and imaginary parts of the complex dielectric function, energy loss, real and imaginary parts of the refractive index, and absorption coefficient, are analyzed for photon energies up to 20 eV to evaluate the optical response.eninfo:eu-repo/semantics/openAccessDouble PerovskiteMechanical PropertiesNa2ZrTeO6Optoelectronic PropertiesArticle8610.1002/adts.20240142185219539014WOS:001430471500001Q2
