Subramanian et al. [1] had reported that CCTO has high dielectric constant (>105), which is nearly constant over a wide range of frequencies and temperatures.
Previously, Young et al. [2] have studied the effect of liquid-phase sintering on the breakdown strength of BaTiO3 (BT) ceramics used for energy storage capacitor, but, as reported, the dielectric constant of BT was only around ~100 at 1 MHz.
Zhang et al. [11] have reported that the energy density of BT was 0.37 J/cm3.

A qualitative study by Nete et al [4] carried out on the three different pegmatites originating from Mozambique revealed that the samples exhibited different degrees of radioactivity and ferromagnetism.
El-Hussaini and Mahdy [7] reported acid leaching of tantalite minerals collected from Kab Amiri using H2SO4 at different temperatures and acid concentrations.
The minerals’ characterization as studied by Nete et al [4], revealed only the physical properties of the samples.
A recent study by Nete et al [12] has investigated the influence of other experimental factors such as temperature and sulphuric acid concentration.
