Whitlockite — Wikipédia
La whitlockite est un minéral essentiellement composé de phosphate de calcium, de formule chimique Ca 9 (Mg,Fe) (PO 4) 6 PO 3 OH. C'est un minéral relativement rare, que l'on trouve dans les pegmatites granitiques, les gisements de phosphate, les grottes de guano et dans les météorites chondritiques.
Whitlockite - Wikipedia
Whitlockite is a mineral, an unusual form of calcium phosphate. Its formula is Ca 9 (Mg Fe )(PO 4 ) 6 PO 3 O H . [ 2 ] [ 3 ] [ 4 ] It is a relatively rare mineral but is found in granitic pegmatites , phosphate rock deposits, guano caves and in chondrite meteorites . [ 4 ]
Whitlockite - Encyclopédie
La whitlockite est un phosphate de calcium secondaire des pegmatites granitiques complexes qui se rencontre parfois aussi dans les dépôts phosphatés ou dans des grottes, cristallisant aux dépens de guano. C'est aussi le constituant de la plaque dentaire.

3 déc. 2013 · The synthesis of pure whitlockite (WH: Ca18Mg2 (HPO4)2 (PO4)12) has remained a challenge even though it is the second most abundant inorganic in living bone. Although a few reports about the precipit...
Whitlockite - Encyclopedia
Whitlockite is a secondary calcium phosphate of complex granitic pegmatites that is sometimes also found in phosphate deposits or in caves, crystallizing at the expense of guano. It is also the constituent of dental plaque. It was named in honor of Herbert Percy Whitlock, Curator of the Department of Mineralogy at the American Museum of Natural ...
