Zr_2P_2WO_(12)powder was successfully prepared by using hydrothermal method,followed by preparation of Zr_2P_2WO_(12)/Fe-Ni composites close to the density by using vacuum hot pressing sintering method.The performance and characterization of Zr_2P_2WO_(12) and Zr_2P_2WO_(12)/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 densit...
