Compound Hg2Sr2-xBaxCa2Cu3O10 high temperature superconductor looks like (HTSC) has been prepared as a pellet by two step solid state reaction with a certain substitution percentages (0.5, 1,1.5,2) of Ba compensation rate of Sr respectively using appropriate weight of pure material Hg2O3, Sr(NO3)2, Ba(NO3)2, CaCO3, and Cu(NO3)2 proportional to their molecular weight. XRD used for study structure properties, a computer program was used to calculation of spike dimensions the lattice parameters a, b and c shows Tetragonal, Electrical resistivity at x= 1.5 of Ba are obtained when the best value of Tc= 142 K.

AbstractLi3Y(BO3)2 was prepared by high-temperature solid state synthesis at 900°C in a platinum crucible from lithium carbonate, boric acid, and yttrium(III) oxide. The compound crystallizes monoclinically in the space group P21/c (no. 14) (Z=4) isotypically to Li3Gd(BO3)2. The structure was refined from single-crystal X-ray diffraction data: a=8.616(3), b=6.416(3), c=10.014(2) Å, β=116.6(2)°, V=494.9(3) Å3, R1=0.0211, and wR2=0.0378 for all data. The crystal structure of Li3Y(BO3)2 consists of [Y2O14] dinuclear units, which are interconnected to each other by planar B(1)O3 groups and LiO4 tetrahedra via common edges and corners along the a axis.
