Dataset for Non-isotropic contraction and expansion of samples in diamond anvil cells: Implications for thermal conductivity at the core-mantle boundary

The dataset contains thickness (diamond-to-diamond) distances measured at the center of the diamond anvil cell cavity filled with MgO, KCl, NaCl, Al2O3, aSiO2 (fused silica), and argon upon compression and decompression.

该数据集收录了在钻石对置砧腔中心测得的厚度（钻石间距离）数据，该腔室填充有氧化镁、氯化钾、氯化钠、三氧化二铝、熔融二氧化硅（二氧化硅玻璃）以及氩气，在压缩与减压过程中的测量结果。
