The rate of formation of microcrystalline hydroxyapatite from amorphous calcium phosphate
has been studied at constant temperature as a function of the pH of the mediating solution; …

The noncrystalline phase was prepared by adding rapidly while stirring a 0.250 molar
solution of (NH4) 2HP04toa0. 750 molar solution of CaC12. 6H20, to achieve a final …

The amount of time that actually elapsed during the solution mediated transformation of
amorphous calcium phosphate into crystalline apatite was short and invariable. On the other …

The kinetics of growth of hydroxyapatite seed crystals has been studied at 25 and at
constantphysiological pH instable supersaturated solutions of calcium phosphate. The …

The precipitation of hydroxyapatite, Caio (P04) 6 (OH) 2, from dilute solutions is discussed.
The degree of supersaturation of these dilute solutions (10s to 109, relative to …

Both the kinetics and the microstructure of monolithic hydroxyapatite formed by a low‐
