摘 要：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.
