  • Organic binder for shaping ceramic, its production method and product employing the same
    Patent number: 5925444
    Abstract: A multilayer ceramic substrate comprising at least one ceramic layer made by laminating at least one ceramic green sheet layer and conductor layers formed on surfaces of the at least one ceramic green sheet layer into laminates and by sintering the resulting laminates. Each ceramic green sheet layer comprises a ceramic precursor composition comprising (I) 100 parts by weight of ceramic fine powder having an average particle diameter of 10 microns or less as component (C) and (II) 5 to 30 parts by weight, based on 100 parts by weight of the ceramic fine powder, of an organic binder for bonding the ceramic fine powder. The organic binder comprises (i) 100 parts by weight of a water insoluble polymer of at least one vinyl monomer as a major component of the organic binder, as component (A), and (ii) 1 to 9.5 parts by weight, based on 100 parts by weight of the component (A), of water soluble polymer as component (B).
