In the spinel system Li1-y Ti2O4 the Li content was reduced by oxidative extraction by means of a solution of I2 as well as Br2 in CH3CN or by oxygen. The extraction is associated with a transition of Ti3+ to Ti4+: the system is Li1-y Ti3+1-yTi4+1+y

The dependence of the physical properties on the substitution of small Ln fractions in the system Bi1.75Pb0.25Sr2Ca1−xLnxCu2O8+z with 0 ≦ x ≦ 0.1 is investigated for Ln = Gd, Yb. The superconducting properties are determined by two factors: (i)

Bi-based high- T c superconductors of nominal composition Bi 2 Sr 2 Ca 3 Cu 4 O 12+ z ( n = 4 phase) were synthesized by an extensive annealing of several hundreds of hours in order to come close to thermodynamic equilibrium. The microstructure revea
