Formation of textural and mechanical properties of extruded ceramic honeycomb monoliths: An 1H NMR imaging study

The main regularities of the texture formation have been revealed using 1H NMR imaging, SEM, XRD, adsorption technique and others. It has been shown that the textural changes of monolith samples at different preparation stages from extrusion to thermal treatment are mostly caused by removal of capillary water (20-100 °C), sintering of small pores and consolidation of oxide particles (100-700 °C), and phase transformation of the oxide component or the binder (900-1300 °C).
