“…Mirror-polished stainless steel or sol−gel-derived particles having submicrometer-level roughness might hinder or impede solvent transport, leading to multiple interfacial interactions. Though there are a multitude of methods for quantifying the particle−particle interactions such as using rheology, sedimentation studies, zeta potential measurements, − or using light-scattering techniques to identify agglomerate sizes, there are very few techniques to actually quantify the interactions of a particle with a vessel or container wall.…”

Force interactions of porous silica particles against mirror-polished stainless steel surfaces were quantified in the presence of various solvents to facilitate processing of ceramics with less reliance on organic aids which subsequently need to be burned off. The results were compared to and found to be in good agreement to idealized models of van der Waals force interactions. Significantly, van der Waals attractive forces between steel surfaces and silica surfaces were minimized through the use of tetrahydrofuran and enhanced using methanol. The solvent selections were further extended to settling behavior and were found to follow the general trends determined by Stokes law. The methods presented herein can be extended to other real-world systems.
