A colloidal processing approach combining the phenomena of depletion flocculation and steric stabilization has been used in the preparation of high‐quality coatings (monolayer and thicker) of silicon particles on silicon carbide fibers. Grafting procedures for the steric additive and the use of the depletion flocculation method to achieve dispersions of relatively high solids concentration are described. The impact of processing parameters on coating quality is demonstrated through electron microscopic images. The relationship between optimal processing parameters and the size and shape characteristics of the solid particles used is also discussed.
