Surface Heterogeneity of Passively Oxidized Silicon Carbide Particles: Hydrophobic–Hydrophilic Partition

A Simple Experimental Way of Measuring the Hamaker Constant A11 of Divided Solids by Immersion Calorimetry in Apolar Liquids

“…To our knowledge, the value of immersion enthalpy of silicon carbide measured in n-heptane is the highest ever observed. We discuss this result in a previous paper (25). Nevertheless, the value of A 11 measured by calorimetry and by application of Eq.…”

Unsteady-State Flow of Flexible Polymers in Porous Media

“…Thus, the permeability of sand packs may be quite high and poorly reproducible; the effective pore diameter is then poorly defined. The material that satisfies the above two requirements for a model porous medium is silicon carbide (SiC) powder (10). This granular material is currently used as an abrasive and has excellent mechanical properties.…”

“…The grain surfaces are partially coated with a thin layer of silica due to a thermal treatment designed to obtain a passive oxidation (see Section II.c and Ref. (10)). …”

Evaluation of Surface Enthalpy of Porous Aluminosilicates of the MCM-41 Type Using Immersional Calorimetry: Effect of the Pore Size and Framework Si:Al Ratio

“…Nevertheless, the results can be collated for different liquids and solids and subsequently used to predict the behavior of interfaces created between these phases. In particular, it is possible to evaluate the proportion of surface acidity to surface basicity for powdered solids with heterogeneous surfaces, for which precise contact angle measurements are not feasible (9).…”
