三种不同的Pb3O4相所表现出的衍射线展宽在环境压力和升高的压力进行了研究。的扩大表明强烈的各向异性的微观应变，这是解释与强烈的各向异性的弹性性能的（局部）应力变化。特别是，利用Pb3O4的各向异性的压缩性确定的基础上，目前的数据，在所采用的金刚石压砧单元的压力波动，由于非流体静力学条件下的样品进行了估计。
The diffraction-line broadening exhibited by three different Pb3O4 phases was studied at ambient and elevated pressures. The broadening indicates strongly anisotropic microstrain, which was interpreted in terms of (local) stress variations in association with strongly anisotropic elastic properties. In particular, making use of the anisotropic compressibility of Pb3O4 determined on the basis of the present data, the pressure fluctuations in the employed diamond anvil cell due to non-hydrostatic conditions of the sample were estimated.
