• Crystalline Nitridophosphates by Ammonothermal Synthesis
  作者：Mathias Mallmann、Sebastian Wendl、Wolfgang Schnick

  Nitridophosphates are a well‐studied class of compounds with high structural diversity. However, their synthesis is quite challenging, particularly due to the limited thermal stability of starting materials like P3N5. Typically, it requires even high‐pressure techniques (e.g. multianvil) in most cases. Herein, we establish the ammonothermal method as a versatile synthetic tool to access nitridophosphates

  磷酸亚硝酸盐是一类经过充分研究的具有高结构多样性的化合物。但是，它们的合成非常具有挑战性，特别是由于起始材料（如P 3 N 5）的热稳定性有限。通常，在大多数情况下，它甚至需要高压技术（例如，多砧）。在这里，我们建立了氨热法作为一种通用的合成工具，以访问具有不同缩合度的亚硝酸磷酸盐。α-栗10 P 4 Ñ 10，β-栗10 P 4 Ñ 10，李18 P 6 Ñ 16，钙2 PN 3，SRP使用铵基条件，在高达1070 K和200 MPa的温度和压力下，在超临界NH 3中合成8 N 14和LiPN 2。通过粉末X射线衍射，能量色散X射线光谱和FTIR光谱分析产物。此外，我们建立了红磷作为硝化磷酸酯合成的原料，代替了常用的和不易获得的前体，例如P 3 N 5。这打开了有希望的制备途径来获得新兴的亚硝基磷酸化合物类。
• Benzene-thermal preparation of nanocrystalline chromium nitride

  Nanocrystalline CrN was successfully prepared through the liquid-solid reaction of anhydrous CrCl3 and Li3N, via a benzene-thermal method in the temperature range of 350-420 degrees C, which is much lower than that used in conventional methods. This process is simple and easy to control. X-ray diffraction (XRD) indicated that the compound was cubic CrN phase with cell constant a = 4.13 Angstrom. Transmission electron microscopy (TEM) images showed that the average particle size was about 25 nm. X-ray photoelectron spectroscopy (XPS) indicated that the as-prepared products contained a small amount (less than 20%) of amorphous carbon. (C) 1999 Elsevier, Science Ltd.
• Solid state metathesis routes to Group IIIa nitrides : comparison of Li3N, NaN3, Ca3N2 and Mg3N2 as nitriding agents
  作者：I.P. Parkin、A.M. Nartowski

  日期：1998.6

  Reaction of MCl3 (M = Sc, Y, La) with Li3N, NaN3, Ca3N2 and Mg3N2 at 380-800 degrees C in sealed glass or Pyrex ampoules for 1-2 h produces MN in good yield. The metal nitrides were characterised by X-ray powder diffraction, electron probe analysis,: FT-IR and microanalysis. Variations in reaction initiation temperatures, nitride composition and crystallinity were correlated with nitriding agent. (C) 1998 Elsevier Science Ltd. All rights reserved.
• The composition and structures of covalent carbon nitride solids synthesized by solvothermal method
  作者：Qiang Lv、Chuan-Bao Cao、Jia-Tao Zhang、Chao Li、He-Sun Zhu

  Crystalline carbon nitrides have been synthesized by using a novel solvothermal method in which the reaction temperature and pressure were varied to determine the possible range for the formation of the crystalline phases. The chemical composition and states of elements were analyzed using X-ray photoelectron spectroscopy, electron energy-loss spectroscopy and Fourier transform infrared spectroscopy. X-ray diffraction (XRD) was used to characterize the powder structure. The maximum percentage of the single C-N bonding in the powder was 55%, which is close to the theoretical value and the XRD pattern indicates the powder is mainly composed of alpha-C3N4 and beta-C3N4.
