The dielectric behavior of composite materials (barium zirconium titanate / epoxy system) was analyzed as a function of ceramic concentration. Structure and morphologic behavior of the composites was investigated by X-ray Diffraction (XRD). Fourier transformed infrared spectroscopy (FT-IR). Raman spectroscopy. https://www.espumasyterciopelo.com/product-category/balloons-airwalkers/
