The polarization-electric field (P-E) loops reveal the ferroelectric nature of the BZCT/ZnO composites. The energy storage properties of BZCT/ZnO composite ceramics as a function of different wt. % of ZnO are found to be optimum at 1 wt. % with a recoverable energy density of 2.61 J/cm3 and an efficiency of 74.2%, at an electric field of 282 kV/cm

It is observed that the rhombohedral and tetragonal phases co-exist in BCZT-BZ samples sintered at different time periods, except the one sintered for 11 h, where the rhombohedral and pseudocubic phases co-exist. The energy dispersive x-ray spectroscopy (EDS) revealed the presence of the elements constituting the BCZT-BZ samples.

When an item of property, plant and equipment or an intangible asset is considered to be impaired, the impairment loss is recognized in the income statement for the period.The decision to recognize an impairment loss involves estimates of the timing and amount of the impairment, as well as analysis of the reasons for the potential loss.Furthermore, additional factors, such as technological obsolescence, the suspension of certain services and other circumstantial changes are taken into account.
