  The authors describe the compound formation in the system Y/sub 2/O/sub 3/-V/sub 2/O/sub 5/ studied by the alkoxy-method. Crystallized YVO/sub 4/ is prepared by the simultaneous hydrolysis of yttrium and vanadyl alkoxides, followed by washing and drying. The chemical structure is described by the formula Y(VO/sub 4/). The as-prepared YVO/sub 4/ powder gives large aggregates of fine particles. Specific

  Abstract The synthesis of Y 1-x/2 Mg x V 1-x/2 O 4-δ (Mg x YV) (x = 0.0–0.5) by solid state reaction technique is reported. This preparation method is compared with chemical synthesis method such as nitrate-citrate auto-combustion route. The crystal structure and the surface morphology of the samples were determined by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) techniques, respectively

  摘要 报道了通过固相反应技术合成Y 1-x/2 Mg x V 1-x/2 O 4-δ (Mg x YV) (x = 0.0–0.5)。将该制备方法与硝酸-柠檬酸盐自燃路线等化学合成方法进行比较。样品的晶体结构和表面形貌分别通过 X 射线衍射 (XRD) 和扫描电子显微镜 (SEM) 技术确定。观察到燃烧法的相形成温度显着降低。发现 Mg 在 YVO 4 晶格中的溶解度极限很低，即 x ≤ 0.1。Mg x YV 样品的电导率的温度依赖性表明，与母体 YVO 4 相比，离子电导率值增加，这是由于由受体 Mg 阳离子的结合产生的氧离子空位的形成。
• Synthesis of Nd:YVO₄Thin Films by a Sol-Gel Method

  Nd: YVO4 powders and thin films were successfuly synthesized by the sol–gel method using metal alkoxides. A homogeneous and stable solution was prepared by the reaction of Y(OEt)3, VO(OiPr)3, and Nd(OEt)3 in 2‐methoxyethanol. The precursor was a mixture of vanadium and yttrium double alkoxide. Precursor films were prepared by dip coating and crystallization to single‐phase YVO4 at 500°C. Nd:YVO4 films were crystallized with (200) preferred orientation on glass substrates, which showed the characteristic optical absorption of neodymium.

• Preparation of YVO4 powder from the Y2O3 + V2O5 + H2O system by a hydrolysed colloid reaction (HCR) technique
  作者：Sandor Erdei

  Prior to the formation of YVO4 in the Y2O3 + V2O4 + H2O system, two intermediate, partially hydrophobic, complex colloidal mixtures with metastable characteristics can be produced at room temperature and atmospheric pressure. The ball-milled system, having both hydrophobic and hydrophilic species, transforms into the stable yttrium orthovanadate phase due to intensive hydrolysis. At room temperature an orange mixture (possessing dispersed Y2O3 and 4Y(2)O(3-p)(OH)(p)(p+). 2VO(3)(-), Y2O3-p(OH)(p)(p+). 6VO(3)(-). XH(2)O-like heteroaggregations) formed by 20 h mixing at pH ca. 4.0 transforms slowly, another red-brown heavily flocculated colloidal mixture (with dispersed Y2O3 and Y2O3-p(OH)(p)(p+). V10O286-. yH(2)O-like aggregation) formed by 70 h mixing at pH ca. 4.5 transforms rapidly into YVO4 in water. During additional mixing of highly diluted red-brown mixtures this transformation can be completed at room temperature. At elevated temperatures (50-95 degrees C) the orange mixture precipitates into a red-brown decavanadate-type precipitatium which subsequently can also rapidly hydrolyse into an orthovanadate phase in the diluted aqueous systems. Both vanadium excess meta- and decavanadate-type aggregations exhibit amorphous character by X-ray diffraction.The semi-hydrophobic colloidal structure can modify the dissociation mechanism, which prevents the system from returning to the starting oxides, and gives a new HCR technique for YVO4 preparation with a simple hydrolysis process at low temperatures and atmospheric pressure.
