摘要

提出了一种合成双氧化锆和磷酸钠的方法，其组成为NaZr2(PO4)3，与NASICON族有关，通式为Na1 + xZr2SixP3-xO12，其中x = 0。采用松香熔体中含有有机组分混合物的溶液的热解方法。确定了合成低维化合物的最佳条件。考虑了前驱体组合物的各种变体。结果表明，在前驱体中加入少量含硅组分，可以在1000 ~ 1200℃的煅烧温度下获得最纯净的NaZr2(PO4)3组合物。这些研究扩展了合成NASICON材料的方法列表。

Production of Double Sodium Zirconium Phosphate with NASICON Structure by Solution Pyrolysis in Melt

A method for producing double zirconium and sodium phosphate of the composition NaZr₂(PO₄)₃, related to the NASICON family with the general formula Na_{1 +} _xZr₂Si_xP₃–xO₁₂, where x = 0, is proposed. The method of pyrolysis of a solution containing a mixture of organic components in a rosin melt is used. Optimum conditions for the synthesis of a low-dimensional compound are determined. Various variants of precursor compositions are considered. It is established that adding small amounts of a Si-containing component to the precursor makes it possible to obtain the purest NaZr₂(PO₄)₃ composition at a calcination temperature of 1000–1200°C. The studies expand the list of methods for synthesizing NASICON materials.
