Abstract
Porous spodumene-cordierite honeycomb bodies of high strength but low volumetric density, useful for the manufacture of close-coupled engine exhaust converters, gasoline engine particulate exhaust filters, and NOx integrated engine exhaust filters, are provided through the reactive sintering of batches comprising sources of magnesia, alumina and silica together with a lithia source, such as a spodumene or petalite ore.
