用激光加热金刚石池测量了Sn的熔化曲线，将熔化曲线扩展到68 GPa和2300 K。最初，Sn的熔化温度随着压力的增加而线性增加（dT/dP约为40 K/GPa），并且在接近38 GPa（2200 K）时熔化曲线为S（dT/dP约为0），表明熔化时的体积相变为零。结果是在良好的协议与以前报道的冲击熔化研究。与Sn相比，Pb的熔化曲线相对于100 GPa是线性的，100 GPa是进行测量的最高压力。
Measurements for Sn, made using the laser-heated diamond cell, are reported that extend the melting curve to 68 GPa and 2300 K. Initially the melting temperature of Sn increases linearly with increasing pressure (dT/dP approximately 40 K/GPa) and near 38 GPa (2200 K) the melting curve flattens (dT/dP approximately 0), indicating a zero volume phase change at melting. The results are in good agreement with previously reported shock melting studies. In comparison to Sn the melting curve of Pb is relatively linear to 100 GPa, the highest pressure at which measurements have been made.
