Abstract: Li3PO4 ceramic targets were prepared by traditional solid-state sintering method. The effects of the sintering temperature on the microstructure, the mechanical properties and the density were discussed. The phase structure of the as-prepared targets was analyzed by X-ray diffractometer. The fracture morphology was observed by SEM. The bending strength was measured by the universal testing machine and the Vickers hardness was measured by the Vickers microhardness instrument. The density was measured using the Archimedes drainage method. The results show that the optimal sintering temperature is 800 ℃, resulting in a bending strength of 76.16 MPa, a Vickers hardness of 475.87HV0.3 and a relative density of 98.89%, which are excellent for a ceramic target material. XRD results indicated the sintered target having a good crystallinity.
