  • The relation between the interfacial contact and SiO[sub]2 coating efficiency and properties in the case of two clarithromycin polymorphs
    Maver, Uroš, 1983- ...
    Two clarithromycin polymorphs with very similar particle size and morphology were coated with silica using a base-catalyzed sol-gel procedure. It was foundthat the contact angles, evaluated from ... measured surface free energies, correlate well with coating efficiency. The connection between interfacial contact (described with the contact angle), nucleation kinetics and coating performance was established using the heterogeneous nucleation theory. The resulting coating thickness and morphology were evaluated by means of thermal analysis, X-ray powder diffraction and scanning electron microscopy. Good agreement was found between the theoretical predictions and experimental findings.
