• Description: This apatite is formed by the same methods as the calcium apatite analog. The solid-state reaction required is: 6SrHPO4 + 3SrCO3 + SrF2 + heat?Sr10F2(PO4)6 + 3CO2 + 3H2O It has also been prepared by the solution method: 10SrF2 (aq) + 6Na3PO4 (aq)?Sr10(F)2(PO4)6 (solid) + 18NaF (aq) + 2HCl However, the product is contaminated by Na+ ions and must be washed thoroughly to obtain a pure product. A small amount of hydroxyapatite may also be present.Strontium fluorapatite has been shown to be one of the best hosts for Nd3+ doping among apatite crystals. Neodymium-doped strontium fluorapatite crystal has been grown by the Czochralski method. The data of thermal expansion and specific heat of the crystal have been measured. The thermal expansion coefficients along X and Z direction are a1 =11.4×10-6/K and a3 = 12.3×10-6/K, respectively. The specific heat is 110 cal/mol K at 330 K. The measured absorption spectra from 400 to 850 nm showed that the crystal has absorption peaks around 805.5 nm, and the absorption coefficients at 805.5 nm are 16.05/cm and 5.59/cm for p and a-polarization, respectively. Strontium fluoroapatite does not have a CAS number even though it is still used as a phosphor for compact and standard fluorescent lamps. It has been the subject of numerous academic studies but has found little or no usage in industry except those already mentioned.
• Uses: Apatite is one of a few minerals produced and used by biological micro-environmental systems. The primary use of apatite is in the manufacture of fertilizer, it is a source of phosphorus. It is occasionally used as a gemstone. Green and blue varieties in finely divided form, are pigments with excellent covering power.
