摘要：

A low-temperature strain-induced chemical reaction and spark plasma sintering (SPS) were employed, for the first time, to prepare a consolidated form of the silver-doped hydroxyapatite (Ag-HA) as a potential biomaterial for bone fracture healing. In a quick sintering segment, Ag-HA was uniformly consolidated, while sustaining its stability. The XRD patterns showed a minor decomposition at 950 degrees C and some alterations were recorded in the structural characteristics. The microhardness of the compacted specimens increased from 613 HV for pure HA to 637 HV for the doped sample. (C) 2020 Elsevier B.V. All rights reserved.
