'CERMEP, France Abstract The sintering behaviour of a glass powder compact has been investigated at the grain scale using X-Ray computed microtomography (XCMT) and Monte Carlo simulation. XCMT is a non-destructive 3D characterisation technique that have provided, in our case, a series of 3D Images of the morphological evolution during sintering of the same grain set. It has been possible to extract from these images the neck growth kinetics. This result has been compared to the numerical result for the two-particle system produced by a newly developed Monte Carlo methodology. Unlike other calculations based on the Potts model, this methodology minimises a non-discrete energetical potential including real surface energies as well as the elasti
