## Abstract The influence of foreign ions on the crystal lattice of hydroxyapatite (precipitated from aqueous solution by a conventional method at 96βΒ°C with a given ratio of Ca/P=1.67:1) was studied during heating in air in the temperature range of 25β1250βΒ°C. The lattice constants decreased to th
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
