Polycrystalline MgB2 was prepared from Mg and boron precursors consisting of boron powders with varying purity and form. Tc does not change largely for all samples. By replacing 10 wt.% of high purity amorphous boron with impure crystalline boron, comparable Jc to that of samples prepared from high...
