Description

Struvite CAS NO 15490-91-2 is a crystalline phosphate mineral composed of magnesium ammonium phosphate hexahydrate. This compound is of significant commercial and environmental interest as a high-value, slow-release fertilizer and a key recoverable product from wastewater treatment processes. It is essential for industries focused on sustainable agriculture, nutrient recovery, and advanced water purification technologies.

Application

• As a premium, slow-release fertilizer providing essential nutrients (N, P, Mg) for horticulture and precision agriculture.
• In nutrient recovery systems for wastewater treatment plants to remove and valorize phosphorus and nitrogen.
• As a raw material for the production of magnesium-based chemicals and flame retardants.
• In laboratory research as a model compound for studying crystallization processes and scale formation.
• For the remediation of nutrient-rich water bodies to prevent eutrophication.
• As a component in specialty cements and construction materials.
