We have developed a dissolved oxygen (DO) method with differential equation (DE) correction. We measured the oxygen content in La-based and Y-based superconductors, and succeeded in measuring the oxygen content simply in one-third of the time require

The oxygen deficiency of SnO 2 was investigated by thermogravimetric analysis (TGA). The powder samples were reduced in 0.5% H 2 /N 2 at 200–500 °C and, their weight changes were evaluated by TGA under flowing O 2 . The results showed that the res

It is known that Cu valence of cuprate superconductors govern transition temperature (Tc). For La2-xSrxCuOy, when x = 0.15, that is, Cu valence is 2.15, the highest Tc around 40K is achieved. The Cu valence is determined both by strontium and oxygen

Polycrystalline Gd 1− x Ca x BaSrCu 3 O 7− δ samples (0 ≤ x ≤ 0.1) were prepared via solid-state reaction. The superconducting critical temperature T c and lattice parameter decrease with doping content. Temperature dependence of the specifi

Avrami’s equation was found to be the best kinetics theory to describe the high- T c Bi-2223 crystal formation so far. There are three parameters (exponential index n , activation energy E and parameter k ) in the equation. A series of research wor
