Theoretical mass of struvite
Struvite (magnesium ammonium phosphate) is a phosphate mineral with formula: NH4MgPO4·6H2O. Struvite crystallizes in the orthorhombic system as white to yellowish or brownish-white pyramidal crystals or in platy mica-like forms. It is a soft mineral with Mohs hardness of 1.5 to 2 and has a low specific … Visa mer Struvite was first described in 1845 by the German chemist Georg Ludwig Ulex [de] (1811–1883), who found crystals of struvite in what he surmised had once been a medieval midden in Hamburg, Germany; … Visa mer Struvite readily forms in alkaline conditions where its constituent ions are present. In nature, it forms primarily in areas associated with organic matter decomposition, including guano deposits, basaltic caves, and marshlands.
