The effects of electrolytes on the rates of hydroxyapatite (HAp) formation at 25 and 38°C were investigated. Solutions were selected to contain ions in common with HAP lattice ions or to contain ions capable of substituting into HAP. The effects of phosphate, calcium, chloride, and fluoride were stu

The addition of different amounts of hydroxyapatite crystals (HAP) to a solution, metastably supersaturated with respect to calcium oxalate (CaOx) resulted in heterogenous crystallization at seed concentrations exceeding 0.2 mmol/l. The induction period varied between 1 and more than 8 h with the sh
