Agglomeration and densification processes during sintering reaction have been analyzed through the use of X-ray tomography. Agglomeration and densification degrees were quantified by calculating the X-ray transparency of 0.25 × 0.25 mm pixels. Evaluation of sintered part in the bed whether the part is weakly, appropriately or excessively bonded and clustering degree are possible with the technique. When excess fuel is used for sintering reaction, uneven sintering phenomonon occurs, resulting larger and denser lump of sintered parts and unsintered parts generated simultaneously. It is recognized to be possible to describe agglomeration and densification processes by the percolation model of fractal theory.
