The interaction of a number of nanosized (20–50 nm) and larger (3–4 μm) additives of refractory nitrides (AlN, HfN, TiN, ZrN, NbN, Si3N4, etc.) with the ceramic superconducting compound (Bi,Pb)2Sr2Ca2Cu3O10 + δ has been considered. The phase composition of the compounds, the cation composition of the existing phases, the morphology of the matrix grains and precipitates, and a number of functional characteristics (T C, J C, magnetization, density, and hardness) have been investigated. The possibility of increasing the critical current density and magnetization at 4.2 and 77 K by a factor of more than 3, as well as the physicomechanical properties (density and hardness), has been established.
