| Fluorine never occurs as an element in nature, but is found in minerals such as fluorspar, fluorapatite, and cryolite. |
|
| The intermediate zone consists of massive lilac-gray sodalite with inclusions of nepheline, dark green aegirine, and pale green fluorapatite. |
|
| Manganese can replace up to 10 percent of the calcium in fluorapatite derived from granite pegmatites. |
|
| It is very similar to fluorapatite in the hornfels environment, from which it is difficult to distinguish visually. |
|
| The district also produced many other mineral species in attractive specimens, including honey-golden barite, fluorapatite, gold, polybasite, rhodochrosite, and tetrahedrite. |
|
| Still, the idea that hydroxyapatite in buried bone undergoes gradual change to fluorapatite is a correct one. |

| Palladium-silver ceramic alloy with properties coordinated with IPS d. SIGN fluorapatite glass-ceramic. |
|
| Collophane, massive cryptocrystalline apatite, composing the bulk of fossil bone and phosphate rock, commonly carbonate-containing fluorapatite or fluorian hydroxylapatite. |
|
| Pure aesthetics thanks to the fluorapatite glass-ceramic material with the true-to-nature properties ranging from the light optical features to the enamel-like abrasion behaviour. |
|
| Biocompatible, remineralising and easy-to-apply fillings and sealants of very small glass particles and fluorapatite for primary and permanent teeth. |
|
| This raw material is shown below as fluorapatite, though the exact composition may vary. |
|
| For further information on the fluorapatite press ceramic and its processing techniques, please refer to the IPS e.max ZirPress Instructions for Use. |
|
| Addition of fluorapatite particles to Glass Carbomer is patented. |

| Tumanov, Solid solution formation at the sintering of hydroxyapatite fluorapatite ceramics. |
|
| The higher density of dots of the phosphorus and calcium gives a reasonable outline of a crystal of fluorapatite. |
|
| The mineral fluorapatite crystalises onto the surface of the tooth. |
|
| However, an intriguing task is to find out, whether any OH-containing carbonate fluorapatite variety characteristic of the Recent lingulate shells is preserved. |
|
| This localisation promotes remineralisation of enamel with fluorapatite. |
