摘要：

The production of a cobalt spinel (Co3-xAlxO4(x = 0,1,2)) based ceramic composite from the heat induced collapse of cobalt exchanged sodium zeolite-A (Co/Na zeolite-A) has been studied both in situ and ex situ using synchrotron radiation XRD and XAFS techniques. The precipitation of this phase is accompanied by the transitory presence of nepheline (NaAlSiO4) indicating the intermediate behaviour of this system between that of Na zeolite-A, which fully precipitates nepheline on heating, and Zn/Na zeolite-A which does not exhibit any nepheline production over the temperature range studied.
