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.
The study included nickel powder support by nano titanium oxide and silicon carbide (SiC) using the powder method wherein titanium oxide cementing percentages (5,10,15,20)% were taken while silicon carbide (SiC) was at a constant rate of 5% with The base material which of is nickel. Then, mixing the powders with an electric mixer for a two hours and pressing them with an electric piston at (5ton) for one minute. The resulting samples were sintered by a thermal oven at (1100°C) and using the argon gas to reduce oxidation for a period of only two hours. The structural structure of the models was studied by using a scanning electron microscope (SEM), as well as a study of mechanical properties that included hardness, compressive strength and wear. The results of the scanning electron microscope showed the homogeneity of the components of the mixed materials characteristically after the high sintering process, and the results of hardness before sintering were (90-132) Hv, when reinforcing from (0-20) %TiO2 while reaching the value of (110-189) Hv are reinforcing from (0-20) %TiO2 with sintering 1100°C, researchers also find that the compressive strength before sintering is (14-.822) MPa when reinforcing from (0-20) %TiO2, while it reached the value of (17.8-32) MPa when supporting from (0-20) %TiO2 and sintering 1100°C, while the wear rate after sintering was the lowest value which is at (20 TiO2%).
The two step Solid-State method used to prepared a whole range materials including mixed metal oxides and nitrides in different concentrations (x = 0.1, 0.2, 0.3, and 0.4). samples were then subjected to Nano technique under hydrolic pressure 8 ton/cm 2 samples have been sintrig in (850 0 C). The resultes show that Samples morphology were observed by AFM (in three dimensions), the best value of Nano is 88.61 nm at x= 0.2.. Electrical resistivity at x = 0.2 of Ag are obtained when the best value of Tc= 140 K.
