摘要：

We present experimental evidence for viscous sintering phenomena in a gel formed by highly viscous emulsion droplets. When a rupturing agent is added to the initially stable emulsion, a gel forms, which further contracts by preserving the geometry of the container. The initial stages of densification (up to 60%) follow very well the "cylindrical model" for viscous sintering, but deviate at the final stages of densification. The observed inverse dependence of the contraction rate on viscosity is consistent with the viscous sintering theory.
