Title:
MOLDED CERAMIC AND PROCESS FOR PRODUCING MULTILAYERED CERAMIC ELECTRONIC PART
Document Type and Number:
WIPO Patent Application WO/2010/024188
Kind Code:
A1
Abstract:
A ceramic green sheet obtained using ceramic particles which, even when highly reduced in particle size, are less apt to aggregate.  The green sheet hence is less apt to cause failures, e.g., short-circuiting, even when having been molded so as to give a ceramic layer reduced in thickness. The surface of the ceramic particles in the ceramic green sheet, which becomes a ceramic layer (2), has been coated with a polymeric dispersant constituted of a copolymer comprising structural units (A) represented by general formula (1) contained in an amount of 5-45 wt.% of all structural units, structural units (B) represented by general formula (2) contained in an amount of 50-90 wt.% of all structural units, and structural units (C) represented by general formula (3) contained in an amount of 0.05-0.7 in terms of ratio by weight to the structural units (B).
