Abstract

Powder diffraction data and refined unit cell parameters of two palladium borides were determined. For Pd3B (space group Pnma; Fe3C type) it was found that a=0.54602(3) nm, b=0.75596(4) nm, c=0.48417(4) nm and for Pd5B2 (space group C2/c; Mn5C2 type) a=1.27759(12) nm, b=0.49497(5) nm, c=0.54704(4) nm, β=97.049(7)°. Further, it was shown that the position of the principal scattering peak of the amorphous Pd2B fulfils the Nagel–Tauc criterion about glass forming ability.
