Abstract:Zr2P2WO12 powder was successfully prepared by using hydrothermal method, followed by preparation of Zr2P2WO12/Fe-Ni composites close to the density by using vacuum hot pressing sintering method. The performance and characterization of Zr2P2WO12 and Zr2P2WO12/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 Zr2P2WO12 powder prepared by hydrothermal method is single-phase of high purity. The grain of Zr2P2WO12 powder is regular and the grain size is about 50nm. With the increase of Zr2P2WO12 percentage, the hardness of Zr2P2WO12/Fe-Ni composites increases, while the density and the relative density decrease. The average thermal expansion coefficient of the as-prepared composites decreases from 13.5×10-6/℃ to 8.6×10-6/℃ with the temperature changing between 25℃ and 800℃.
