Preparation of a New Porous Apatite Product from Phosphorite
A new porous apatite product was prepared using phosphorite from Yichang China by a template-directed method in self-made reaction equipment under constant temperature and pressure.The product was characterized by XRD, FT-IR and SEM. The results showed that the product was a kind of micrometer porous sphere three-dimensionally structured by apatite nanoflakes, that the average thick ness of nanoflakes was about 50 nm, that the average pore size was about 1.2 μm and that the particle average size was about 20 μm. Great amounts of Ca2+ channel, high special surface area and regular spherical shape show the potential promising applications of this special porous apatite product in the fields of catalyst, medication, chemical engineering and environment engineering.
