Crystal growth microstructural examination

The effect of Gel on the nucleation and growth of cHAp crystals and its subsequent influence on the microstructure of the sintered body was examined by Shu et al. [243]. Investigators synthesized cHAp in the presence of Gel molecules. Their experimental results indicated that the concentration of the Gel solution is a predominant factor in inhibition of nucleation and growth. This inhibition is believed to relate strongly to the covalent interaction between Ca + ions in the solution and the R-(COO) ions of Gel molecules. It also influences the Ca P ratio, and subsequently affects the microstructure of the sintered body.
