Abstract Alumina-sodium chloride (Al 2 O 3 -NaCl) composite (1:1 ratio in weight percentage (wt%)) is cold sintered at 120 °C. The cold sintered composite with a densification of 96% has e r and tan δ values 6.53 and 0.007 respectively at 1 MHz. The microwave dielectric properties of Al 2 O 3 -NaCl composite at 5 GHz are e r = 6.04 and tan δ = 0.002 with τ e value +32 ppm/°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.
