| dbo:abstract | La childrenita és un mineral de la classe dels minerals fosfats. Va ser descobert l'any 1823, nomenant-lo en honor de John George Children (1777–1852), químic i mineralogista anglès. (ca) Childrenite is a rare hydrated phosphate mineral with elements iron, manganese, aluminium, phosphorus, oxygen and hydrogen. Its chemical formula is (Fe2+,Mn)2+AlPO4(OH)2•H2O and it has a molecular weight of 229.83 g/mol. Its specific gravity is 3.2 and it has a Mohs hardness of 4.5 to 5. It is usually translucent and non-fluorescent, with imperfect cleavage. It has a vitreous lustre with a white streak, and is brown or yellow in color. It has a conchoidal, uneven fracture, and an orthorhombic crystal system. (en) Childrenit ist ein eher selten vorkommendes Mineral aus der Mineralklasse der „Phosphate, Arsenate und Vanadate“ mit der idealisierten chemischen Zusammensetzung Fe2+AlPO4(OH)2·H2O und ist damit chemisch gesehen ein wasserhaltiges Eisen-Aluminium-Phosphat mit zusätzlichen Hydroxidionen. Da Childrenit mit Eosphorit (Mn2+Al[(OH)2|PO4]·H2O) eine lückenlose Mischreihe bildet, ist in natürlichen Childrenitproben oft ein Teil des Eisens durch Mangan ersetzt (substituiert). In verschiedenen Quellen wird daher die chemische Formel auch mit (Fe2+,Mn2+)Al[(OH)2 |
