Thermal and mechanical properties of polycrystalline BaSnO3
چکیده انگلیسی

A polycrystalline sample of BaSnO3 was prepared from SnO and BaCO3 powders by simple solid-state reactions. The thermal expansion coefficient, heat capacity, thermal diffusivity, thermal conductivity, elastic modulus, Debye temperature, and micro-Vickers hardness were measured. The crystal structure of BaSnO3 is of the cubic perovskite type with a lattice parameter of 0.4116 nm at room temperature. The sample bulk density is 95% of the theoretical density. The average linear thermal expansion coefficient is 9.3 × 10−6 K−1 in the temperature range between 300 K and 1773 K. The value of Young's modulus is 244 GPa. The thermal conductivity at room temperature is 9.7 W m−1 K−1.
