Abstract

In a process for forming elements from a slurry that includes particulate ceramic and/or glass, an organic binder resin, and a solvent for the resin, where the element is shaped from the slurry, and the element heated to remove the organic materials of the slurry and subsequently fuse the ceramic and/or glass particles, the improvement comprised of coating the ceramic and/or glass particles prior to forming the slurry with a surface modification compound selected from the group consisting of organo silanes, organo silazanes, titanium chelates, titanium esters, and mixtures thereof.
