Abstract: | Biphasic calcium phosphate (BCP) nanopowders were synthesized by using microwave and non-microwave irradiation assisted processes.
The synthesized powders were pressed under a pressure of 90 MPa, and then were sintered at 1000–1200°C for 1 h. The mechanical
properties of the samples were investigated. The formed phases and microstructures were characterized by X-ray diffraction
(XRD) and scanning electron microscopy (SEM). The results showed that the synthesis time was shorter, along with a more homogeneous
microstructure, when the microwave irradiation assisted method was applied. The compression strength and the Young’s modulus
of the samples synthesized with microwave irradiation were about 60 MPa and 3 GPa, but those of the samples synthesized without
microwave irradiation were about 30 MPa and 2 GPa, respectively. XRD patterns of the microwave irradiation assisted and non-microwave
irradiation assisted nanopowders showed the coexistence of hydroxyapatite (HA) and tricalcium phosphate (TCP) phases in the
system. |
