| Abstract: | Hydroxyapatite (HA)-barium titanate (BT) of human bone imitating composite material was prepared by sintering process with HA powder and BT powder as raw material，and then was characterized by XRD, SEM with EDS, synchronous thermal analyzer, universal material testing machine, quasi-static piezoelectric coefficient measuring instrument and dielectric constant measuring instrument. The results show: the partial decomposition of HA and BT resulted in the reaction of the raw materials in the pressed block at certain temperature to produce CaTiO3, Ca3(PO4)2, TiO2, BaTi2O5 and other phases. The bio-piezoelectric HA-BT composite containing 70% BT sintered at 1200℃ is composed of grains uniform size with good compactness and comprehensive property closed to those of human bone, such as compressive strength (110.215 MPa) and electrical properties (d33=2 pC/N, εr=44.6). |
