Abstract
A binder for preparing an aqueous ceramics slurry, which contains a hydrophilic polymer such as a water-soluble (meth)acrylic polymer, a polysaccharide of natural origin such as pectin, pectinic acid, glucan, etc., and a polyvinyl compound such as poly(vinyl butyral). The aqueous ceramics slurry contains less than 25 parts by weight of the binder to 100 parts by weight of ceramics powder. The slurry is applied on a carrier film by a doctor blade method and dried to give a ceramics green sheet. A ceramics sheet can be produced by sintering the green sheet.
