Which compound is triple phosphate formed in alkaline urine?

Triple phosphate crystals, also known as struvite, form in alkaline urine. They are composed of magnesium ammonium phosphate (MgNH4PO4·6H2O) and precipitate when the urine pH is high and the ions NH4+, Mg2+, and PO4^3− are present. This condition is often linked to infections with urease-producing bacteria (which raise pH by hydrolyzing urea to ammonia), creating the right environment for these crystals to form. The result is the characteristic crystalline appearance and, in many cases, the formation of struvite stones. Other phosphate-related possibilities are not the same crystalline compound, so the classic scenario for alkaline urine is the formation of triple phosphate.
