Alumina-sodium chloride (Al2O3-NaCl) composite (1: 1 ratio in weight percentage (wt%)) is cold sintered at 120 degrees C. The cold sintered composite with a densification of 96% has epsilon(r) and tan delta values 6.53 and 0.007 respectively at 1 MHz. The microwave dielectric properties of Al2O3-NaCl composite at 5 GHz are epsilon(r) = 6.04 and tan delta = 0.002 with tau(epsilon) value +32 ppm/degrees C. The energy saving cold sintering process (CSP) indicates the possibility to integrate with polymers as well as metals for the fabrication of electronic products. (C) 2017 Elsevier B.V.
