  Crystal structure of a new polytype in the V–P–O system: is ω-VOPO4 a dynamically stabilised metastable network?

  摘要：

  omega -VOPO4 has been prepared by thermal decomposition of different oxovanadium hydrogen phosphates, namely VO(HPO4) nH(2)O (n = 2(alpha), 2(beta) and 4) and beta -NH4(VO2)(HPO4). The omega -VOPO4 phase only remains well crystallised at relatively high temperatures. Its crystal structure has been determined ab initio from X-ray powder diffraction data collected at 4750C. The cell is tetragonal (space group P4(2)/mmc) with a = 4.8552(3) Angstrom and c = 8.4301(6) Angstrom. Starting positional parameters were obtained by direct methods, and the structure was refined using Rietveld profile refinement principles. Disorder of two oxygen sublattices is observed. To rationalise some features of the crystal structure of this new phase, a dynamic model is proposed and discussed. (C) 2001 Elsevier Science Ltd. All rights reserved.

  Physicochemical processes during thermal treatment of vanadium and phosphorus oxides mixture (1) as well as with diammonium hydrophosphate (2) in the closed system (autoclave) have been studied. In the first case, at 300 °C, the defective structure γ-VOPO4 is formed and in the second case, there was established possibility of synthesis of vanadyl hydrophosphate—the precursor of vanadyl pyrophosphate (the catalyst of n-butane oxidation to maleic anhydride). At the same time, various phases of mixed ammonium and vanadium phosphates were obtained at lower and higher temperatures.

  研究了在封闭系统（高压釜）中对钒磷氧化物混合物（1）以及磷酸氢二铵（2）进行热处理时的物理化学过程。在第一种情况下，在 300 ℃ 下，形成了缺陷结构 γ-VOPO4；在第二种情况下，确定了合成焦磷酸钒（正丁烷氧化成顺丁烯二酸酐的催化剂）的前体--氢磷酸钒的可能性。同时，在较低和较高的温度下，还得到了各种相混合的铵和钒磷酸盐。

  Solid-state reactions in VxOy (NH4VO3)-P2O5 and VxOy (NH4VO3)-(NH4)(2)HPO4 closed systems can be used to synthesize vanadyl hydrogen phosphate at 300 degrees C and a variety of ammonium vanadium phosphates at lower and higher temperatures.
