APPLIED CRYSTALLOGRAPHY SOLUTIONS TO PROBLEMS IN INDUSTRIAL SOLID-STATE CHEMISTRY - CASE EXAMPLES WITH CERAMICS, CEMENTS AND ZEOLITES

We show that a number of processes involved in the field of industrial solid-state chemistry can be successfully studied in situ using a ran ge of crystallographic and related techniques. The adaptation of relev ant equipment to reproduce the process environment at the sample is a crucial part of the approach. Examples are given, involving the synthe sis of zirconia-based ceramics, hydration of cements, and dehydration of zeolites, where successful applications of this approach have uncov ered new structural/kinetic aspects concerning seemingly well establis hed industrial processes.
