Dilatometric and microstructural study of particle and functionally graded composites based on hydroxyapatite and crystalline bioglass

Hydroxyapatite (HA) and bioglass (BG) ceramics have become of prime importance in bone tissue engineering. Besides the appropriate composition, microstructure replacement plays a crucial role. In present work, particle composites functionally graded material (FGM) based on HA BG prepared by electrophoretic deposition were thoroughly characterised terms preparation method, sintering process, phase composition microstructure. The was monitored high-temperature dilatometry two directions, rates calculated, overall process discussed. SEM showed continuous change FGM with gradual interconnected porosity favourable for bio-applications. fundamental fractographic analysis proved crack development related to recommendations reduction given. transformations during thermal treatment analysed using X-ray diffraction deeply
