Abstract

The effect of the solid/solution (S/S) ratio on apatite formation from CaSiO3 ceramics in simulated body fluid (SBF) was investigated. CaSiO3 ceramics with a Ca/Si ratio of 0.91 were prepared by sintering CaSiO3 powder coprecipitated from ethanol solutions of Ca(NO 3)2·4H2O and Si(OC2H 5)4 using NH4OH as the precipitant. These ceramics were reacted with SBF at S/S ratios of 1.0, 2.5 and 8.3 mg/ml at 36.5°C for various times. Formation of apatite was observed at all the S/S ratios after soaking for 1 day. The amount and microstructure of the apatite obtained at a S/S ratio of 8.3 mg/ml, however, differed largely from the product formed at the other two S/S ratios. The apatite formed at S/S = 8.3 mg/ml was of smaller particle size, formed in smaller amount and with less preferred orientation of the (00l) of apatite crystals compared with those formed at S/S = 1.0 and 2.5 mg/ml. An increase of Ca and decrease of the P components occurred in the soaked SBF at S/S = 8.3 mg/ml, the changes being much more marked than with the other two S/S ratios. These differences in the concentration changes in SBF at different S/S ratios are attributed to the difference in the apatite formation from the CaSiO3 ceramics.
