Development of magnesium-doped biphasic calcium phosphate through sol-gel method
Published 2008“…FTIR spectroscopy measurement also showed that the increment of crystallinity is directly proportional to the amount of dopant leading to the conclusion that magnesium acts as a sintering additive. This result is in good agreement with the analysis of FESEM where the particles of the Mgdoped BCP are larger as the amount of dopant increased as a result of more progressive fusion of particles.…”
