An abrasive particle having a body including a first major surface, a second major surface opposite the first major surface, and a side surface extending between the first major surface and the second major surface, such that a majority of the side surface comprises a plurality of microridges.

A system and method to dry plug cement in a ceramic honeycomb body during the manufacture of plugged ceramic honeycomb bodies. The system includes a heating element (520) configured to immediately heat without contact a face (502) of a ceramic honeycomb body (500) plugged with a wet plug cement (510) to rapidly dry and stiffen the plug cement (510) on the face (502) of the ceramic honeycomb body (500). The method includes immediately applying heat without contact to a face (502) of a ceramic honeycomb body (500) having wet plug cement (510) disposed in channels (508) of the ceramic honeycomb body at the face, and rapidly drying and stiffening the plug cement on the face of the ceramic honeycomb body.

A fluid heating component including: a porous body made of ceramics and formed with through channels through which a fluid passes, and a conductive coating layer disposed on a through channel surface of at least a part of each through channel, wherein the conductive coating layer is electrically connected, and is continuous.
