Nano crystalline ceramic PbSrCaCuO was prepared by the solid state technique via a high-energy ball milling process through mechanically assisted synthesis.The prepared sample was then subjected to calcinations to acquire the desired homogeneity and phase formation. To establish the elemental composition EDX analysis was done.TGA and DTA were used to study the behaviour of the sample upon heating to a high temperature.

The prospects of using nano-crystalline ceramic coatings on internal combustion engine parts obtained by micro-arc oxidation (MDO) technology are considered. The tendency of development of engine building on replacement of cast-iron blocks and sleeves on aluminum with the special coverings received by galvanic methods is shown. It is noted that this direction does not involve the use of repair technologies, which significantly affects consumers. Analysis and practical tests have shown the possibility of using MDO technology both in the manufacture of engine parts and for the performance of restoration work. It is concluded that it is necessary to introduce this technology into the mass production of engines and pistons, as well as the need to develop a set of equipment for repair work.

Crystalline Ceramic Lanthanum Zirconium Yttrium barium Calcium Copper oxide(L0.1ZY0.9BCCO)  was prepared by a high-energy ball milling process through mechanically assisted synthesis at a high temperature to acquire the desired homogeneity and phase formation. Inorder to study the optical properties like reflectivity, absorptivity, refractive index, the UV-VIS analysis of the above nonstochiometric sample was carried out. The dispersion of refractive index was analyzed by the Wemple-DiDomenico single-oscillator model.The band gap energy of the sample was elucidated from the Tauc plot. The refractive index n was calculated and  the results obtained are plotted  with the wavelength.
