摘要

本文首次利用低温和高温x射线衍射在93 ~ 513 K的温度范围内对过渡金属氧硼酸盐沃wickite (Fe2+，Mg)Fe3+(BO3)O进行了研究。揭示了其热膨胀具有明显的各向异性。从阳离子多面体和氧中心多面体的作用两方面给出了膨胀机理的结构解释。

Anisotropy of Thermal Expansion of Oxoborate Warwickite

In this paper, the transition metal oxoborate warwickite (Fe²⁺,Mg)Fe³⁺(BO₃)O is studied for the first time by low- and high-temperature X-ray diffraction in the temperature range from 93 to 513 K. The sharply anisotropic nature of its thermal expansion is revealed. A structural interpretation of the expansion mechanism is given both in terms of the contribution of cationic and oxocentered polyhedra.
