struvite

(strū′vīt)
Magnesium ammonium phosphate crystals, important in health care because they cause about 15% of all kidney stones. They are formed in the urinary tract in conjunction with some bacterial infections, such as infection with Proteus mirabilis, and in some patients with hypercalciuria.

Results showed that crop emergence in the control treatment, except for struvite, was significantly higher than the emergence in the DAP and organic fertilizer treated plots at the Bahati and Lanet sites (Table 1).
[3] Alkaline urine caused by urea-splitting organisms (Proteus, Klebsiella, Serratia and Enterobacter) is responsible for struvite stones (ammonium magnesium phosphate stones).
This characteristic means chemical reactions, such as precipitation to form struvite or calcium phosphate, require extensive chemical additions or take place very slowly (Ibarra, 2011).

In this reaction, a phosphate gel was formed as a precursor of the ceramics since the metal oxide dissolved to release cations reacted with the hydrolytic phosphate ions, and the main final phase of hydration product is struvite, but many other phases also existed during or after hydration reaction, such as dittmarite (N[H.sub.4]MgP[O.sub.4]*[H.sub.2]O), schertelite ([(N[H.sub.4]).sub.2]Mg[(HP[O.sub.4]).sub.2]*4[H.sub.2]O), newberyite (MgHP[O.sub.4]*3[H.sub.2]O), and magnesium phosphate hydrate [Mg.sub.3][(P[O.sub.4]).sub.2]*4[H.sub.2]O [12, 13].
