Phosphoric Acid → Calcium biphosphate

Participants

Reaction Steps

According to an advantageous embodiment of the invention, the method comprises a mixing of phosphoric acid with an aqueous suspension of calcium hydroxide, a formation of a first precipitate of calcium monohydrogenphosphate (DCP), a separation between the first precipitate and an aqueous solution of calcium dihydrogenphosphate (MCP), an addition to this aqueous solution of a strong base and a separation between a second precipitate and a clear solution of calcium dihydrogenphosphate (MCP), forming the said mineral additive.
