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

The effects of the nature of oxide component and binder, and thermal treatment temperature (100 °C and from 600 to 1300 °C) on textural and physicochemical properties of honeycomb monoliths based on alumina, titania and aluminosilicates have been studied. 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).
