Figure 4
The diffraction patterns for PbSiO3 glass measured in the HXD95 showing the glass compressed to 2.5 GPa at ambient T, crystallization at 873 K, and the fully molten liquid at 1100 K (solid black curves). The broad peaks in the raw pattern at 873 K for Q > 8 Å arise from the diamond anvils. The red dashed curve is the empty cell background measurement. For clarity, the results are displaced vertically. |
