Title: X-RAY COMPUTED TOMOGRAPHY POTENTIAL FOR COMMERICAL DRY-PRESSING

Abstract:
Our experiences with the use of X-ray computed tomography in the investigation of dry pressing will be presented. These range from the early stages or compaction through to the final stages of sintering. Batch compositions have included both clay-based materials and single-phase Adds powders. Numerous opportunities for cost reduction and quality enhancement remain to be exploited in the typical commercial dry-pressing process. Additionally, advances in detector package technology have made the possibility of in-line tomograph examination during production considerably less costly than in the past. Software enhancement provides automated scanning and data interpretation capabilities. However, this transition will require tradeoffs in both the state-of-the-art tomographic capabilities and complete statistical understanding of process. We show that there are distinct benefits to the manufacturer in spite of these drawbacks.
