Characterization of calcium phosphate cements modified by addition of amorphous calcium phosphate

Acta Biomaterialia, 2010
In this study the influence of amorphous calcium phosphate (ACP) on the setting of, and the formed apatite crystallite size in, a calcium phosphate cement (CPC) based on alpha-tricalcium phosphate (alpha-TCP) or tetracalcium phosphate (TTCP)/monocalcium phosphate monohydrate (MCPM) was investigated.

Development of a new calcium phosphate cement that contains sodium calcium phosphate

Biomaterials, 2001
A cement powder consisting of sodium calcium phosphate, Na3Ca6(PO4)5, in addition to tetracalcium phosphate and beta-tricalcium phosphate was prepared by pulverizing blocks of 4 wt% sodium-, 11 wt% carbonate-containing apatite samples that were heated at 1700 degrees C for 5 h.

Phospholipid—Calcium Phosphate Complex: Enhanced Calcium Migration in the Presence of Phosphate

Science, 1971
In the presence of acidic phospholipids, inorganic phosphate greatly enhances the net migration of calcium ions from the aqueous phase to the organic phase, an effect that does not occur at less than the physiological p H.

Inhibition of calcium phosphate crystallization by nucleoside phosphates

Calcified Tissue Research, 1974
The 5′-triphosphates of adenosine, guanosine, uridine, and cytidine inhibited the crystallization of calcium phosphate from stable supersaturated solutions that had been seeded with crystals of hydroxyapatite. Concentrations of the nucleoside triphosphates in the micromolar range were sufficient to have a significant effect on the crystal growth ...

Conversion of octacalcium phosphate in calcium phosphate cements

Journal of Biomedical Materials Research, 2000
This study investigated the in vitro conversion reaction in calcium phosphate cements (CPCs) containing octacalcium phosphate (OCP) as one of the reagents. OCP is known to be a precursor for apatite formation in vivo. The reaction products were characterized using infrared spectroscopy and X-ray diffraction.
