Abstract
Monodispersed ellipsoidal hematite particles were synthesized and coated with silicone using a silanecoupling agent phenyltriethoxysilane The thickness of the silicone shell was controlled by the concentration of phenyltriethoxysilane and the presence of nhexadecyltrimethylammonium chloride which was thought to modify the surface properties of the hematite particles to be organophilic The hematite/silicone coreshell particles were strongly hydrophobic and had a good dispersibility and stability in toluene Hollow ellipsoidal silicone particles were obtained by the dissolution of hematite with hydrochloric acid from the coreshell particles
