Research output: Contribution to journalArticlepeer-review


The time-course for crystalline forms of calcium phosphates was investigated by the X-ray method in the absence and presence of citrate, a typical inhibitor of calcium phosphate formation. Dicalcium phosphate dihydrate (DCPD) was observed as a precursor without citrate, while DCPD was not observed in the presence of citrate, suggesting that citrate lowered the supersaturation degree of DCPD.
