dc.description.abstract | Struvite (MgNH4PO4·6H2O) is a mineral first
identified in 1845. It is tested for several reasons: (1) it is a
problem in liquid wastewater treatment plants; (2) on the other
hand, it is recovered from this wastewater because of phosphorus,
magnesium, and nitrogen; (3) it is the main component of
infectious urinary stones. In this paper, we present the first
experimental evidences of the ferroelectric nature of struvite at
room temperature. Struvite shows a hysteresis loop and
spontaneous electric polarization that can be reversed by an
application of an external electric field. The measured value of
residual polarization of struvite is equal to 0.95 μC/cm2. We also report observations of the ferroelectric domains in struvite using
birefringence imaging technique. The non-centrosymmetry of the crystal lattice is confirmed with the use of the Kurtz−Perry powder
test. The second harmonic generation response for struvite in relation to that of potassium dihydrogen phosphate is 0.36. We suggest
that ferroelectric properties for struvite, in particular, spontaneous polarization, can have a significant impact on the behavior of
struvite in aqueous solutions, such as liquid wastewater or urine. | pl_PL |
