ABSTRACT:
The invention provides exemplary silicon carbide ceramic bodies and processes for making such ceramic bodies. In one embodiment, a raw batch for producing a ceramic body includes a silicon carbide slurry and agglomerates of particles defining a dry lubricant mixture. The mixture includes a binder and a dry lubricant such as graphite, with a majority of the agglomerates having a shape that is generally spherical.
