Abstract The microemulsion solution is composed of isooctane
as oil phase, sodium bis(2--ethylhexyl) sulfosuccinate (AOT) as surfactant,
1--octanol as cosurfactant, Ca(H$_{2}$PO$_{4}$)$_{2}\cdot$H$_{2}$O
solution and Ca(OH)$_{2}$ saturated solution as water phase.
Hydroxyapatite nanoparticles were successfully processed by mixing the both
microemulsions. The partial ternary phase diagram of microemulsions was set
by a series of demarcation points between optically transparent and opaque,
which indicated the single phase area of the composition and the effect of
reactant ions. The diameters of inverse micellars measured by dynamic light
scattering (DLS) depended linearly on water content $w$ ($w$=[H$_{2}$O]/[AOT])
in case that micellars was near spherical morphology. The parameters of
micellars were computed on the reactant concentration, AOT concentration and
average diameter of micellars. Mechanism of reaction and particles growth
showed that the reactant concentration and water content played an important
role for the result particle size.
