Abstract
Porous magnesium diboride samples have been prepared by heat treatment of a pressed mixture of Mg and MgB2 powders. It was found that linked superconducting structure is formed down to the minimum normalized density γc d/do 0.16 (percolation threshold), where d is the density of MgB2 averaged over the sample, do 2.62 g/cm3 is the X-ray density. The critical temperature of the porous samples decreases with increasing porosity (decreasing γ) and T c2 32K is minimal at γc 0.16. © 2006 IOP Publishing Ltd.
