Abstract
PURPOSE: To obtain a superconducting material having high superconductive critical temperature and small difference between the superconductive critical temperature and the temperature to complete phase transition, by sintering a powdery mixture of oxides, carbonates, sulfates or nitrates of four specific kinds of elements.
CONSTITUTION: A superconducting material having a composition of formula (ε is at least one kind of element selected from O, B, C, N, F and S; u, v, w and x are 0 or 1; y is 1W4) is produced by mixing oxides, carbonates, sulfates or nitrates of an element (α) selected from the group IIa and group IIIa elements of the periodic table, an element (β) selected from the group IIa and the group IIIa elements of the periodic table including the same element as the element (α), at least one kind of element (γ) selected from V, Ta, Nb, Cr, Ca, In, Cd, Sn, Tl, Pb, Mo, W and Zn and an element (δ) selected from the groups Ib, IIb, IIIb and VIIIa elements of the periodic table at atomic ratios of (0.5W2):(0.5W3):(1W4):(0.01W0.1) and sintering the obtained powdery mixture at 700W1,600°C.
