Abstract:
Alumina-sodium chloride (Al2O3-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 er and tand values 6.53 and 0.007 respectively at 1 MHz. The microwave dielectric properties of Al2O3-NaCl composite at 5 GHz are er = 6.04 and tand = 0.002 with se 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.
