Abstract Magnesium titanate is a well-known low loss dielectric ceramic, widely used in dielectric resonator and multilayer ceramic capacitor applications. But its high sintering temperature (1400°C) results in high energy consumption and thereby increases the environmental pollution and production cost. Furthermore, traditional sintering methods restrict co-sintering of ceramics with low melting metals and polymers. Cold Sintering Process (CSP) which provides a simple, effective and energy saving strategy for ceramic fabrication has not yet been reported for the fabrication of magnesium titanate based microwave dielectric ceramics. In the present work, dense samples of xMgTiO3-(1-x)NaCl (x = 0–0.5) ceramic composites were successfully prepared by cold sintering process (CSP) for the first time, at
