摘要
拓宽了NaZr_2(PO_4)_3的水热晶化条件,在摩尔比为:P_2O_5/ZrO_2=30～0.75,Na^+/P≥1:3,H_2O/ZrO_2=900～215,pH≤2.0,250℃的条件下,制得了纯相NaZr_2(PO_4)_3晶体,用XRD,IR和Raman光谱对其进行了表征.讨论了水热合成诸因素对产物物相的影响.初步研究了水热生成磷酸锆钠的机理及F^-对NaZr_2(PO_4)_3晶体生长的影响.
The pure NaZr2(PO4)3 crystals were synthesized under the expanded hydrothermal conditions. P2O5/ZrO2 = 30-0. 75, Na+/P≥1 : 3, H2O/ZrO2 = 900-215(molar ratio), pH≤2. 0, 250 ℃. The product was characterized by means of X-ray powder diffraction, infrared and Raman spectrometries. The mechanism of the hydrothermal crystallization of NaZr2(PO4)3 was discussed briefly. Some unsuitable views on the hydrothermal synthesis of NaZr2(PO4)3 in literature were corrected.
