Investigation of layered calcium phosphates and related materials for Biomaterial applications
… This study has concentrated on layered calcium phosphate phases and their analogues due to their obvious biocompatibility and potential for resorption. Materials were prepared using a range of synthetic techniques including ceramic methods, acid flux and hydrothermal synthesis. Some of …

Chemical Controls on the Formation of Amorphous and Crystalline Calcium Phosphates
Transformation of amorphous calcium phosphate (ACP) and brushite into hydroxylapatite, an important biomineral, has been documented. The relationships between synthesis conditions and the formation and transformation of these phases are not comprehensively understood. The metastable nature of ACP …

Production of phosphorus alloys through thermal reactions and electrochemical reduction of molten apatite
… melts into two solid phosphorus rich phases, tricalcium phosphate and tetracalcium phosphate. Fluourapatite behaves in a similar manner, albeit at a higher temperature. These two calcium phosphates can be reduced to calcium oxide and oxygen in the presence of nickel, forming Ni₃P. Included in …

Synthesis And Characterization Of Nanocrystalline Hydroxyapatite Powder; And The Effects Of Oxide-based Sintering Additives On Tricalcium Phosphate
Calcium phosphate (CP) materials have been used extensively for bone replacement and augmentation due to their similarity to the mineral component of bone. In addition to being non-toxic, they are biocompatible, not recognized as foreign materials in vivo, and most importantly, exhibit …

Porous calcium phosphate granules for biomedical applications
… repair by integrating them into the host site. Calcium phosphates are used as medical implants because they have a chemical composition similar to the mineral of human bones, i.e. apatite. For this reason they are biocompatible and they can interact in a bioactive way with bone tissue. In the …

Bioactive Poly(Lactic-co-Glycolic Acid)-Calcium Phosphate Scaffolds for Bone Tissue Regeneration
… 3D architectures. Hydroxyapatite (HAP) and tricalcium phosphate have been used in conjunction with polymer scaffolds due to their osteoconductivity and biocompatibility, but they often lack osteoinductivity and are resistant to biodegradation. Conversely, amorphous calcium phosphate (ACP) is a …

Effects of Surface Characteristics of Hydroxyapatite and Substituted Hydroxyapatites on Protein Attachment and Angiogenesis
… electrochemical features on the bioactivity of calcium phosphates. Additionally, a hOB and HDMEC co-culture methodology was designed to allow in vitro assessment of bone cell attachment and angiogenesis in a physiologically relevant environment.

Phosphate Reactivity in Long-Term Manure Amended Soils in the Ridge and Valley of Virginia
… have exhibited properties that indicate calcium (Ca) may also be limiting P, especially in soils impacted by poultry manure. Accurate estimation of P loss potential is critical for justification of long-term management approaches. To evaluate the accuracy of model estimation of P loss …

3D printing of bone scaffolds using powders derived from biogenic sources
… for the regeneration of bones. At this purpose, calcium phosphates derived from natural sources are very interesting because they are more similar to the bone mineral and possess better bioactivity. Indeed, the bone mineral is different from synthetic hydroxyapatite as it is non-stoichiometric, …
