allowed by the examiner.
The subject matter on appeal relates to a process for
forming a ceramic insulation which includes the step of
diffusing a catalyst into a mat impregnated with a sol for a
catalyst soak time during which the catalyst diffuses into the
mat and causes the sol to gel. The appealed subject matter
also relates to the ceramic insulation produced by a process
of the type previously described. This appealed subject
matter is adequately illustrated by independent claim 11 which
reads as follows:
11. A process for forming a ceramic insulation
comprising the steps of:
(a) forming a slurry of ceramic components selected
from the group consisting of fibers, microparticles, and
mixtures thereof, an effective amount of a metal powder and,
optionally, any of (i) a dispersant, (ii) a flocculant, or
(iii) fugitive microparticles;
(b) molding the slurry to form a mat having a
thickness;
(c) impregnating the mat with a sol;
