Synthesis of porous high-temperature superconductors via a melamine formaldehyde sacrificial template
Source abstract
Abstract
Nanostructured high-temperature superconductors YBa2Cu3O6+δ and Bi2Sr2CaCu2O8+δ were synthesised using a melamine formaldehyde sponge as a sacrificial template, via three solution-based approaches. In the case of YBa2Cu3O6+δ , a modified Pechini method produced a material with a superconducting transition at 92 K and a specific surface area of 4.22 m2 g-1. Further analysis with Hg porosimetry determined that the sponge exhibited a porosity of 82%. In the case of Bi2Sr2CaCu2O8+δ , this method produced a material that exhibited superconductivity at 86 K with a specific surface area of 9.62 m2 g-1. Hg-porosimetry determined that the BSCCO sponge exhibited a porosity of 78%.
