“…Slimani et al [21] studied the impact of ZnO addition on dielectric properties of BaTiO 3 ceramics for radiofrequency and microwave applications. It has been shown that the introduction of BaTiO 3 in the ZnO matrix increases the dielectric constant of the composite and decrease the dielectric loss [22]. This work aimed to obtain dense ceramic composites of ZnO-BaTiO 3 using the cold sintering technique and to study the microstructural, structural, and electrical properties of this composite.…”

The sintering is an essential step in the processing of ceramics materials. A number of researchers have reported new techniques for sintering. However, in general, the process still demands high temperatures. This paper reports the results of the cold sintering of ZnO-BaTiO 3 composites. The microstructural, structural, and electric properties of the composite were studied. We obtained high densities (>95%) for pure ZnO and for the composition with 10 wt% of BaTiO 3 at a low temperature of sintering (250 °C/1 h). The increase of BaTiO 3 content reduced the grain size and degraded the sinterability of ZnO. The crystalline structure was investigated by X-ray diffraction and confirmed the separation of the phases after the cold sintering. The BaTiO 3 added in the composite reduced the values of conductivity, permittivity, and also the dielectric loss.
