The coordination environment around Ni at minor concentration levels (2 wt% NiO) in Na2Si20 5 glass and melt has been investigated by high temperature (293-1250 K) X-ray absorption fine structure (XAFS) spectroscopy. The derived average anharmonic Ni-O distances for the glass at 293 K and the melt a
