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. Similar conditions are found … Visa mer • Website of the European Phosphorus Platform about Phosphorus Recovery Visa mer Use of struvite as an agricultural fertilizer was first described in 1857. It contains P and N, two of the three major plant macronutrients, with Mg being a minor macronutrient as well. Struvite can be produced from urine by adjusting pH (often just by waiting … Visa mer WebbIn fact, struvite can even precipitate spontaneously in pipes, where it forms crystals that contain about 12.6 per cent P per dry mass (theoretical value of pure struvite).
WebbStruvite appears to exhibit intermediate behavior [ 20, 21 ]. Fine particles may also be created by grains abrasion, particularly for seeds of large size or in regions of high turbulence, such as in the zone of reactants mixing.
