| Abstract: | For the first time, the particle distribution and aggregation in Pickering emulsions were made visible by transmission X-ray
microscopy. Oil/water emulsions were stabilized by heterocoagulates of a clay mineral and magnesium aluminum hydroxide. Stability
is optimum when the particles surround the oil droplets and also assemble to form a network extending through the coherent
phase.
