Abstract
The recent success of making metal oxide nanowires via biopolymer-mediated, sol–gel techniques has been extended to Y 3Ba5Cu8O18 (Y358), a new cuprate superconductor. This study was carried out using three long chain biopolymers as templates, namely alginate, dextran and chitosan. X-ray diffraction showed an over-expression of the crystallographic a axis for samples synthesized in the presence of alginate. The critical current densities (Jc) of Y358 synthesized at 920 °C were 5.01 MA cm−2, 6.26 MA cm−2 and 1.24 MA cm−2 for alginate, dextran and chitosan respectively.
