In this article the conventional "solid-state reaction" method was used to synthesize perovskite Li0.4Cd0.6Ba2Ca2Cu3O10+δ. Four main types of compounds were obtained by physically replacing calcium oxide with cadmium in proportions 0, 0.03, 0.06 and 0.09, the pure Li0.4Cd0.6Ba2Ca2Cu3O10+δ phase, and the phases Li0.4Cd0.6Ba2Ca1.97Cd0.03Cu3O10+δ and Li0.4Cd0.6Ba2Ca1.94Cd0.06Cu3O10+δ and Li0.4Cd0.6Ba2Ca1.91Cd0.09Cu3O10+δ ,respectively from mixing their constituent oxides and pressed into pelts and then sintered in the furnace at 850 degrees Celsius for 90 hours: These samples have been studied for their original dielectrically properties. The real dielectric constant, dielectric loss factor, and tangent were calculated in the frequency range (50 to 1000000 HZ). It was found that the partial substitution of cadmium oxide plays an important role in enhancing dielectrically properties.

In this article four samples of HgBa2Ca2Cu2.4Ag0.6O8+δ were prepared and irradiated with different doses of gamma radiation 6, 8 and 10 Mrad. The effects of gamma irradiation on structure of HgBa2Ca2Cu2.4Ag0.6O8+δ samples were characterized using X-ray diffraction. It was concluded that there effect on structure by gamma irradiation. Scherrer, crystallization, and Williamson equations were applied based on the X-ray diffraction diagram and for all gamma doses, to calculate crystal size, strain, and degree of crystallinity. It is observed through the results that gamma irradiation causes a change in the atomic density, crystal size, strain, degree of crystallinity and thus a change in the diffraction angle and intensity peaks. It was found that the highest crystal size was 69.3269 nm at 4MRad dose, crystallization is 69.3269 at 4MRad and the strain is 0.0068 when sample without radiation.

The major problems that facing sustainability is the heat production with electricity transmission. The research and engineering communities hope that superconductive materials will be employed in the power transmission, without any losses along the way. Solid-state reaction is a one of the methods for preparing compound samples. This method was used to prepare the nominal chemical formula Y2Ba4Cu7O15. The calcining of the mixed powder at constant temperature of 800C0, followed by compressing the mixed, under (7, 8, 9) tons/cm2 pressures, as pallets shape with diameter 1.5 cm and thickness (0.2-0.3) cm inducing. The prepared samples were encounter many sintering processes through constant temperature. The sintering processes were done in the furnace by rising and cooling temperature with Oxygen rate 0.5 L/min. The samples were measured electrically to determine the resistivity changes in different temperatures (77–300) K, using four-probe technique. The results for the samples A, B and C shows the onset superconducting transition temperatures (Tc (onset)) at 88 K, 93 K, and 99 K respectively. The XRD data illustrated a polycrystalline structure for all samples. The transition temperature, oxygen content (δ) and the lattice parameter increase with increasing the pressure.
