Abstract
In the present study, the effect of a high magnetic field, “magneto vector field effects”, on the development of their microstructure of ceramics was mainly investigated. The compactions of hydroxyapatite with an addition of disodium phosphate were in-situ sintered at 1000°C and 1100°C in air atmosphere under a high magnetic field of 10 tesla. Their microstructures of hydroxyapatite sintered bodies were evaluated by X-ray diffraction (XRD) technique and scanning electron microscopy (SEM) observation. It was found that hydroxyapatite with an additive prepared by in-situ sintering with a high magnetic field in an air atmosphere possessed significantly higher relative density than ones sintered under 0 tesla. These results might show the enhancement of densification on in-situ sintering with the effect of magnetic field.
