Preparation and characterization of a titanium-substituted hydroxyapatite photocatalyst

Development and characterization of titanium-containing hydroxyapatite for medical applications

“…The bioactivity and biocompatibility can be further improved by substituting low levels of silicon in the form of silicate groups into the HA structure, demonstrating that chemical modification of HA is a suitable method to enhance its osteoconductive potential. It was decided that the effects of Ti substitution would be investigated by preparing the materials in a similar method to SiHA, which is different from other studies [19,21]. Metal-substituted HA was made by the ion-exchange and coprecipitation methods [19,[21][22][23].…”

Metal-substituted HA was made by the ion-exchange and coprecipitation methods [19,[21][22][23]. Using these methods, HA can be modified by Ti ions, such as Ti(SO 4 ) 2 .…”

Synthesis of nanorod and needle-like hydroxyapatite crystal and role of pH adjustment

“…Meanwhile, HAp can also be absorbent and catalyst. Recently, the surface-OH group in HAp has been found to absorb CO 2 , NO x and organic compounds [3,4]. All the calcium phosphates with different Ca/P ratios are candidate materials for biomedical applications because of their high biocompatibility and forming bonds with living tissues.…”

Biomedical materials and techniques to improve the tribological, mechanical and biomedical properties of orthopedic implants – A review article

“…49 hydrothermal treatment is performed by placing the PEO coated samples in the bottom of autoclave or in pressure controlled reactors containing neutral or alkaline aqueous solution and treated hydrothermally within the temperature range of 100-250 o C for 2-24 hrs at pH 7-11 [148], [149]. Figure 59 reveals the surface morphologies of the as-prepared TiO 2 films after pre-immersion in 0.1, 1, and 2 M K 2 HPO 4 for 10 min and then soaking in SBF solutions for 1, 2, 4, and 9 days [150].…”
