PROCESS FOR THE PRODUCTION OF CERAMIC GREEN SHEETS

摘要

Ceramic green films having advantageous isotropic distribution of the inorganic pigment can be obtained by casting and drying a slip containing finely divided inorganic pigment, organic solvents, polyvinylbutyral, plasticizer and dispersing agent if compounds which contain in their molecules at least one structural unit of the formula Z (Z) in which A and B, which must be different, stand for either the oxyalkylene unit -C3-4H6-8O- or the oxyalkylene unit -C2H4O- and x and y, which can be identical or different, each denote a number from 1 to 200, are used as dispersing agents. Ceramic green films produced according to the invention can be converted to isotropic ceramic substrates by subsequent heat treatment and sintering.
