“…However, using a higher HCl solution removed the intermediate substances [21][22][23][24]. Therefore, future studies should focus on the leaching method, especially the type of acid solution [25][26][27].…”

Titanium carbide (TiC) composite powder was synthesized via the self-propagating high-temperature synthesis (SHS) method using leucoxene as a source of titanium oxide (TiO2) and magnesium (Mg) as an initiator. The effect of Mg content on synthesized TiC composite powder was characterized in terms of chemical composition and morphology by X-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques. Results showed that adding 1.5 moles Mg into the reactant system leached with 0.1 M hydrochloric acid solution was the optimal condition, and TiC was apparent in the XRD analysis at a particle size of less than 150 μm.

Calcium titanate powder was successfully prepared from duck eggshell and anatase titanium dioxide with a magnesium inductant via combustion synthesis in argon. As-combusted products were leached with diluted HCl. In XRD analysis, as-leached powders exhibited a major phase of CaTiO3 with a perovskite structure. The particle size, observed by SEM, was approximately 240 nm. As-leached powders were densified by single-step (SST) and two-step sintering (TSS) to produce calcium titanate ceramics. The first step of all TSS conditions was fixed at 1350C and holding times (t1) at this temperature were varied up to 120 min. Calcium titanate ceramic obtained from holding for 120 min had a grain size of 2.18 ?m, relative density of 86.68% and a dielectric constant of 92. Two-step sintered ceramic had the highest density (95.73%) and best dielectric properties (dielectric constant = 110, dielectric loss = 0.02) when the holding temperature (T2) was 1250?C. Calcium titanate ceramics processed by two-step sintering had denser microstructures and higher dielectric constants than single-step sintered ceramic due to grain boundary diffusion and the simplicity of relaxation polarization.
