| description | Zr<sub>2</sub>P<sub>2</sub>WO<sub>12</sub> powder was successfully prepared by using hydrothermal method, followed by preparation of Zr<sub>2</sub>P<sub>2</sub>WO<sub>12</sub>/Fe-Ni composites close to the density by using vacuum hot pressing sintering method. The performance and characterization of Zr<sub>2</sub>P<sub>2</sub>WO<sub>12</sub> and Zr<sub>2</sub>P<sub>2</sub>WO<sub>12</sub>/Fe-Ni composites materials were carried out by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermal expansion analyzer. In addition, the hardness of the composites was tested using Vickers hardness instrument and the density of the as-prepared composites was characterized by using drainage method. The results show that the Zr<sub>2</sub>P<sub>2</sub>WO<sub>12</sub> powder prepared by hydrothermal method is single-phase of high purity. The grain of Zr<sub>2</sub>P<sub>2</sub>WO<sub>12</sub> powder is regular and the grain size is about 50nm. With the increase of Zr<sub>2</sub>P<sub>2</sub>WO<sub>12</sub> percentage, the hardness of Zr<sub>2</sub>P<sub>2</sub>WO<sub>12</sub>/Fe-Ni composites increases, while the density and the relative density decrease. The average thermal expansion coefficient of the as-prepared composites decreases from 13.5×10<sup>-6</sup>/℃ to 8.6×10<sup>-6</sup>/℃ with the temperature changing between 25℃ and 800℃. |
