1. A method of reinforcing a ceramic body comprising a honeycomb structure comprised of a plurality of intersecting walls extending from a first end to a second end in an axial direction, the plurality of intersecting walls defining a plurality of channels extending in the axial direction, the method comprising:
applying an alumina particle mixture to the first end and the second end of the honeycomb structure, the alumina particle mixture comprising alumina particles including boehmite nanoparticles and gamma alumina microparticles;
heating the honeycomb structure for a time and at one or more temperatures sufficient to convert at least some of the boehmite nanoparticles on the honeycomb structure into gamma alumina nanoparticles.
