Description Three-dimensional numerical simulation was performed to show that coarsening and grain growth was affected by particle arrangement in sintering of identical spheres. In the sintering of a row of three spheres the center particle with the coordination number of 2 coarsened, while particles on both sides with coordination number of I shrank and disappeared. The particles on both sides disappeared in a shorter time with increasing ratio of grain boundary energy gamma(gb) to surface energy gamma(s). A new bond between two particles on both sides was created during sintering of three spheres with bond angle of 70 degrees. This particle rearrangement changed the coordination number, and retarded the coarsening.
