FREMGANGSMAATE FOR FREMSTILLING AV SINTREDE LEGEMER OG SAMMENSETNINGER FOR BRUK I DISSE

摘要

The invention relates to a method of preparing sintered shapes, comprising the steps of: (1) forming a green body from a mixture comprising (A) at least one inorganic powder with (B) at least one polymer derived from (a) at least two sulfo monomers or (b) a combination of (i) a sulfo monomer with (ii) at least one monomer selected from acrylic compounds, acrylonitriles, vinyl lactams and vinyl pyrrolidones and maleic acids, anhydrides or salts, provided the mixture is substantially free of polysaccharide;and (2) sintering the green body. Inorganic shapes made from the compositions of the present invention have relatively high fired densities; small uniform grain sizes; and relatively low porosity.
