摘要：

The evolution of monocalcium phosphate monohydrate (MCP) to dicalcium phosphate dihydrate (DCPD) depends particularly on the concentration of compounds in solution (Ca2+, H2PO4-, humic matter) and on pH. Complexation of calcium by humic matter involves an increase in the concentration of calcium ions in solution and the adsorption of humic matter at the surface grains of the DCPD formed blocks the active growth sites of DCPD. Therefore, an increase in the amount of humic matter in solution is associated with a decrease in the evolution rate and the amount of DCPD formed.
