• Apatite: Its uses as a mineral and gemstone

    Apatite is best known for its use as an index mineral with a hardness of 5 in the Mohs Hardness Scale. It is usually green in color, but can be yellow, brown, blue, purple, pink, or colorless. These colors are often so vivid that apatite has frequently been cut as a gemstone. Apatite is a brittle material. It breaks by both fracture and cleavage, but the cleavage is generally indistinct ...

  • Blue Apatite: Meanings, Properties and Powers

    Blue apatite is a form of the mineral group that was named apatite in 1786, although the strict definition of this mineral formation was not determined, as it is used today, until 1860. The mineral apatite comes from a Greek word meaning "to deceive," because of its unusual origins. Apatite is difficult to tell from other minerals and to add to the confusion, a form of apatite known as ...

  • Ionactivity products of some apatite minerals

    soils, the apatite minerals have relatively low solubility, and they react only slowly with soils. The problem with the apatites is that they may not provide enough phosphorus in solution to make them effective as ferti­ lizers. Their solubility is thus of great importance. The solubility of apatites has been investigated extensively. Most of the research has dealt with hydroxyapatite, Ca ...

    Apatite is a superb mineral by which to investigate the nature of fluids that have passed through and altered a rock (metasomatic processes). Its ubiquity allows it to act as a reservoir for P, F, Cl, OH, CO 2, and the rare earth is also a powerful thermochronometer and can be chemically altered by aqueous brines (NaCl–KCl–CaCl 2 –H 2 O), pure H 2 O, and aqueous fluids ...

    An important component of phosphorite (phosphate rock) is carbonate apatite, as it is required for phosphorous fertilizer production due to its increased phosphate solubility caused by carbonate substitution in the apatite mineral lattice. High phosphate concentrations in municipal wastewater treatment plants are commonly reduced by precipitating iron phosphate by addition of iron chloride.

    Radiation damage may be repaired through the process of annealing. Experimental evidence suggests that apatite may anneal during alpha particle bombardment (termed "selfannealing"), which, combined with a low solubility in aqueous fluids and propensity to incorporate actinide elements, makes this mineral a promising phase for nuclear waste storage. Apatite evaluated in this study occurs ...
