Preparation of “124” superconductors using only alkoxides
摘要:
The "124" phase (YBa2Cu4O8) is synthesized at a low temperature of 700-degrees-C in O2 gas flow (PO2 = 1 atm) by means of a sol-gel method using only alkoxides. The prepared Cu-butoxide for the present synthesis is soluble up to 36 mMol/l in butanol and hydrolyzable. The sample sintered at 760-degrees-C exhibits superconductivity with the zero-resistance temperature (Tc(R = 0)) at 78 K.
