Phase transitions and diffuse reflectance spectra of barium titanate-zirconate solid solutions
The composition, structure, particle size distribution, diffuse reflectance spectra, integral absorption coefficients of solar radiation and dielectric properties of BaTi(1–x)Zr(x)O3 powders synthesized from micro powders BaCO3, ZrO2 and TiO2 at x = 0 – 0.3 have been studied. Changes in the integral...
