Ginstling-Brounstein Model Used for Diffusion-Controlled Synthesis of Solid Spherical Particles

What is it about?

In this short and simplistic study, we have shown that the Ginstling-Brounstein (GB) model can be used to describe the diffusion-controlled synthesis. One example of such synthesis is wet precipitation (WP) of hydroxyapatite (HAp). We have found that particle size determination has the most significant effect (59.95%) on the kinetic coefficient value calculations and thus the highest attention has to be given to the careful measurements of the particle size in order to obtain K values with a high precision. Also, one can reduce synthesis time by reducing particle radius. Parameters used in this study were characteristic values for a laboratory-scale synthesis of hydroxyapatite.

Why is it important?

This work shows that Ginstling-Brounstein (GB) model can be used for describing synthesis of hydroxyapatite (HAp) and other solid particles. Results provide more insight in understanding the wet precipitation (WP) and particularly hydroxyapatite (HAp) synthesis which is of importance for biomedical as well as sorptive applications.
