ABSTRACT:
In the method of forming a ceramic body, such as for use as a packing body, a dried array of corrugated layers containing ceramic material is first obtained in a green state. Thereafter, the array is cut, for example using a saw, into a desired shape and, thereafter, fired at a firing temperature sufficient to form the array into a one piece ceramic body. The body may initially be cast in a mold which can be cut to shape prior to the final firing step. Alternatively, individual layers of glass fiber material may be coated with ceramic material and dried into the green state prior to cutting and firing.
