✦ Synopsis

vestigated by different techniques, such as small angle X-A colloidal dispersion of calcium hydroxide in a hydrocarray scattering (SAXS) or small angle neutron scattering bonated medium was synthesized by the hydrolysis of calcium (SANS) and transmission electron microscopy (TEM) (12hydride in the presence of a surfactant under specific experimen-17). A core shell model whereby salt spheres are surrounded tal conditions. The hydrolysis of calcium hydride is assumed to by a stabilizing surfactant shell has been proposed.

take place in a water in oil microemulsion. The resulting product

In a previous study, we reported the synthesis of colloidal can be defined as a distribution in hydrocarbon of inorganic particalcium thiophosphate by an original process (18). In this cles made of crystallized calcium hydroxide surrounded by surarticle, we introduce a new colloidal dispersion in which the factant in a reverse type micelle association. Morphological charinorganic particles are made of calcium hydroxide and the acterization of the colloidal dispersion has been investigated using small angle X-ray scattering, transmission electron micros-surfactant is a calcium alkylarylsulfonate. We will begin by copy, and X-ray diffractometry. The inorganic particles appear presenting the synthesis of such a compound, and then we as disks with diameters ranging from 120 to 300 A ˚and a thickness will analyze it from both chemical and morphological standof 30 A ˚.
