What is a Magnesium phosphate (Mg₃(PO₄)₂)?

Magnesium phosphate (Mg₃(PO₄)₂) is an inorganic salt composed of magnesium and phosphate, typically appearing as a white or off-white crystalline powder. This compound is widely used in various industries, particularly in fertilizers and pharmaceuticals. In fertilizers, magnesium phosphate is used to supplement magnesium deficiency in soil, particularly in acidic soils, improving plant growth. It is also found in medications, such as laxatives and pain relievers, to promote bowel movement and alleviate muscle pain.

Magnesium phosphate is known for its high heat resistance and chemical stability, making it suitable for use in ceramics and refractory materials. It is also utilized in metal processing due to its compatibility with metallic materials. It is insoluble in water but can dissolve in acidic conditions, requiring proper management based on the intended application.
