Method of bonding inorganic particulate material, particularly for multilayer ceramic substrates

Prepn. comprises (a) forming a finely divided cpd. that includes particles of ceramic particles, (b) coating the particles with a heat decomposable surface modification organo cpd. (I) selected from organo silanes, organo silazanes, titanium chelates and titanium esters, (c) combining and mixing the coated particles of finely divided cpd. with an organic resin binder and solvent for the binder to form a slurry, (d) shaping the slurry to form the desired element, heating the element to remove the coating, the binder and the solvent and (e) continuing the heating to fuse the particles of finely divided cpd. 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.
