Abstract

We report a new, convenient and simple low-temperature process for synthesis of γ-lanthanum(III) sulfide (γ-La₂S₃). In molten sodium thiocyanate with small KCN additions at a temperature of 350°C, lanthanum oxide converts into phase-pure γ-La₂S₃ with a cubic structure, as evidenced by X-ray powder diffraction data. The method is rather easy to implement and requires neither high temperatures nor vacuum apparatus.

本文报道了一种新的、方便、简单的低温合成γ-镧（III）硫化物（γ-La2S3）的方法。在添加少量KCN的硫氰酸钠熔液中，在350℃温度下，氧化镧转化为具有立方结构的相纯γ-La2S3， x射线粉末衍射数据证实了这一点。该方法易于实现，既不需要高温，也不需要真空装置。

期刊介绍： Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
