Nov 11, 2014· Apatite is the generic name, which was first introduced by German geologist A.G. Werner. These minerals and their synthetic analogs represent a major class of ionic compounds and the most common crystalline form of calcium phosphates, which are of interest of many industrial branches and scientific disciplines. Since, apatite (fluorapatite) is the most abundant phosphate mineral, apatite ...

In order to be used as crop nutrients or animal feed, apatite (the main phosphate mineral) must be converted to a water-soluble form. In general, the phosphate facilities in chemical complexes utilize a wet process in which the phosphate concentrate is mixed with sulfuric acid and filtered to make phosphoric acid which is the starting point in the production of most phosphate derivative products.

Apatite is generally a group of phosphate minerals consisting of high concentration of OH −, F − and Cl − referred to as hydroxylapatite, fluorapatite and chlorapatite respectively. Actually, it is a type of mineral named by German geologist in 1786. Apatite is the most commonly used mineral especially in biological environmental systems.

Apatite Properties and Meaning – Apatite is a member of the Phosphate family. It comes in both massive and crystalline form, with colors ranging from green, yellow, blue and rarely purple. Read more about Apatite healing properties information and view the photo galleries further below.

Apr 01, 2011· Our results show that the formation of apatite occurred more rapidly as the phosphate content increased (Fig. 2c and d), although the NC was kept constant, which indicates that in these glasses the phosphate content is a more important variable than NC (or possibly an overriding factor in a process where NC and phosphate dissolution compete).

As nouns the difference between phosphate and apatite is that phosphate is (chemistry) any salt or ester of phosphoric acid while apatite is (mineral) a calcium fluoride phosphate of variable composition, sometimes used in the manufacture of fertilizer. As a verb phosphate is to treat or coat with a …

The Ethyl process utilizes CaF 2, a by-product of the raw material for a phosphate fertilizer: apatite. Apatite contains also silicates, calcium, and fluorine that can be converted to silicon tetrafluoride in the process of waste utilization (Warren et al., 1985).

A novel process for the fabrication of nanoporous Naturallyabundant Moroccan phosphate Bengurir ores was used as a source for calcium and phosphorus precursors for the synthesis of nanoporous apatites following a dissolutionprecipitation method The influence of temperature ripening time ...

Jun 26, 2016· The aim of the present study was to compare the effect of a conventional fluoride preparation and of modern calcium phosphate or apatite containing prophylactic products on initial erosive mineral loss in a combined in situ/in vitro setup. Surface alterations and layer formation were visualized electron-microscopically.

Calcium phosphate apatites are inorganic compounds encountered in many different mineralized tissues. Bone mineral, for example, is constituted of nanocrystalline nonstoichiometric apatite, and the production of "analogs" through a variety of methods is frequently reported. In another context, the ability of solid surfaces to favor the nucleation and growth of “bone-like” ...

On purely a chemical level, hydroxyapatite is a naturally occurring form of the mineral calcium apatite, also known as calcium phosphate. The majority of the enamel and dentin in your teeth is made from a form of hydroxyapatite.

Biological apatite is an inorganic calcium phosphate salt in apatite form and nano size with a biological derivation. It is also the main inorganic component of biological hard tissues such as bones and teeth of vertebrates. Consequently, biological apatite has a wide application in dentistry and orthopedics by using as dental fillers and bone substitutes for bone reconstruction and regeneration.

Jul 27, 2016· The speciation of phosphate was controlled by pH to favor HPO 4 2−. In a carbonate free system, the reaction produces anisotropic apatite crystallites with large aspect ratios. The first formed crystallites are highly calcium deficient and hydrogen phosphate rich, consistent with thin octacalcium phosphate (OCP)‐like needles.

Large scale mining and processing of phosphate is essential for operating at a profit. In the Florida area, Phosphate Beneficiation by flotation unlocked the door to vast tonnages of ore which in the past could not be recovered by conventional washing methods which saved only the coarser pebble phosphate. Many of the areas now being mined contain very little or no pebble phosphate, so the main ...

"Apatite" is a field term for unidentified calcium phosphate members of the apatite group. Most "apatite" is fluorapatite, whereas hydroxylapatite is much less common and chlorapatite is very rare. "Apatite" crystals are short to long hexagonal prisms [0001], with {10 1 0} and {10 1 1} dominant; also thick tabular {0001}, frequently in the crystals of hydrothermal origin in pegmatites and ...
