Chemistry informtion about Fluorapatite (CAS NO.1306-05-4) is:
IUPAC Name: Dicalcium Fluoride Phosphate
Synonyms: Fluorapatite (Ca₅F(PO₄)₃) ; Fluorapatite
MF: Ca₅FO₁₂P₃
EINECS: 215-144-1

Fluorapatite (CAS NO.1306-05-4) can be used as a precursor for the production of phosphorus. It can be reduced by carbon in the presence of quartz:
4 Ca₅(PO₄)₃F + 21 SiO₂ + 30 C → 20 CaSiO₃ + 30 CO + SiF₄ + 6 P₂
Upon cooling, white phosphorus (P₄) is generated:
2 P₂ → P₄

When heated to decomposition it emits very toxic fumes of F⁻ and PO_x. See also FLUORIDES and PHOSPHATES.

OSHA PEL: TWA 2.5 mg(F)/m³
ACGIH TLV: TWA 2.5 mg(F)/m³; BEI: 3 mg/g creatinine of fluorides in urine prior to shift; 10 mg/g creatinine of fluorides in urine at end of shift.
NIOSH REL: (Inorganic Fluorides) TWA 2.5 mg(F)/m³

Fluorapatite (CAS NO.1306-05-4), can be synthesized in a two step process. First, calcium phosphate is generated by combining calcium and phosphate salts at neutral pH.This material then reacts further with fluoride sources (often sodium monofluorophosphate or calcium fluoride (CaF₂)) to give the mineral. This reaction is integral in the global phosphorus cycle.
3 Ca²⁺ + 2 PO3−4 → Ca₃(PO₄)₂
3 Ca₃(PO₄)₂ + CaF₂ → 2 Ca₅(PO₄)₃F

Fluorapatite (CAS NO.1306-05-4), often with the alternate spelling of fluoroapatite, is a mineral with the formula Ca₅F(PO₄)₃ (calcium halophosphate). Fluorapatite is a hard crystalline solid. Although samples can have various color (green, brown, blue, violet, or colorless), the pure mineral is colorless as expected for a material lacking transition metals. It is an important constituent of tooth enamel. Fluorapatite is the most common phosphate mineral. It occurs widely as an accessory mineral in igneous rocks and in calcium rich metamorphic rocks. It commonly occurs as a detrital or diagenic mineral in sedimentary rocks and is an essential component of phosphorite ore deposits. It occurs as a residual mineral in lateritic soils.
