Control process for the production of a superconductive material with a high critical temperature, characterised in that - the starting point is a mixture of powders of the precursors of the said material with the stoichiometry of the desired superconductive phase, - the said mixture is agglomerated to form a tubular or cylindrical component, - the agglomerated component is placed in a furnace with a controlled atmosphere to perform the synthesis of the said superconductive phase, - the conductivity of the said component is measured continuously, - the temperature at which the conductivity initiates a decrease is exceeded, followed by a return to a value where the conductivity begins to increase again, - the furnace temperature is regulated continuously so as to control the said conductivity (curve C1). <IMAGE> |
