The surface energetics of a powder plays an important role in the ease of preparation, stability and dissolution of pharmaceutical products. Existing techniques for assessing surface energetics of powders (i.e. liquid penetration and contact angles) suffer from practical and theoretical limitations as well as being somewhat subjective. The objective of this study was to evaluate the data obtained by microcalorimetric techniques from which ?H and other kinetic parameters of adsorption can be determined. Results were supplemented by data obtained by vacuum microbalance methods.
