A method of connecting the inorganic particles, in particular for multi-layer 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.
