摘要: Abstract A precipitation diagram of the system calcium chloride-sodium phosphate—0.15 mol dm−3 sodium chloride (pHi = 5.0, 37°C) is represented. Calcium hydrogen phosphate dihydrate (DCPD) precipitated in whole investigated region but recrystallized into anhydrous form (DCPA) at high initial reactant concentrations. The position boundary, as determined constant pH (5.0 ± 0.1) different time intervals (10 min-3 months), was dependent both on observation and concentration ratio. Using these data interfacial energy nucleus for mononuclear growth calculated (σ 50 mJm−2).
