Owing to its applicability in refractory ceramic synthesis, nanoelectronics, optoelectronic and sensing devices, superconducting products, magnesium oxide (MgO) is recognized be an important material. However, it has a relatively low dielectric constant compared other metal semiconductors, which restricts the range of bandgap limits applicability. Therefore, this study, we propose verify method...

Y3(Al,Ga)5O12 (YAGG) materials doped with Ce3+, Cr3+ and Pr3+ were synthesized by using a modified Pechini method subsequently annealed in air at selected temperatures between 900 1500 °C. According to X-ray powder diffraction (XRPD) transmission electron microscopy (TEM) analyses, the particles size distributions become large broad, respectively, due sintering agglomeration high annealing temp...

LiMn2-xTixO4 compounds with 0 ≤ x ≤ 1 were prepared by solid state reaction and Pechini technique. Powder X-ray diffraction showed that all samples crystallize with the spinel crystal structure (S.G. Fd 3 m). The cubic unit-cell parameter increases with Ti content. The influence of the Ti content and cationic distribution on the magnetic properties of the compounds was studied by measuring the ...

The solid solutions of chlorapatite compounds Ba5Mn3 xVxO12Cl (x 1⁄4 0e3.0) and Ba5Mn3 xPxO12Cl (x 1⁄4 0 e3.0) have been synthesized through solid state reactions and Pechini or solegel method using citric acid. The colors of the samples change from white (x 1⁄4 3.0) through turquoise (x 1⁄4 1.5) to dark green (x 1⁄4 0) with increasing amount of manganese. Optical measurements reveal that the o...

In this work, controlled precipitation synthesis methods and polymeric precursors (Pechini) were used to obtain gadolinium-doped cerium oxide solid electrolytes (Ce0.8Gd0.2O1.9) double-doped with gadolinium samarium (Ce0.8Gd0.2−xSmxO1.9 x = 0.01; 0.03 0.05). The main results indicate that the synthesized powders by Pechini method present better microstructural characteristics such as larger spe...
