Patent ID: 8623128

Claim:
A ceramic mass which sets as a result of baking or sintering, wherein the mass comprises: a water-soluble cellulose ether which is characterized by elastic properties in which the ratio of loss modulus G″ to storage modulus G′ (tan δ=G″/G′) of the solution has a value of less than 1.3, wherein the tan δ is measured in an alkaline solution of 1.0 part by weight of the water-soluble cellulose ether per 100 parts by weight of solution at a temperature of 20° C. +/−1° C. when using a solvent comprising 98 parts by weight of water and 2 parts by weight of sodium hydroxide per 100 parts by weight of solvent in a rheological oscillation experiment as a function of the angular frequency ω in the linear viscoelastic region at angular frequencies of less than or equal to 100 rad/s; and at least one compound selected from the group consisting of alumina, aluminum nitride and aluminum carbide, cordierite, mullite, silicon carbide, silicon boride, silicon nitride, titanium dioxide, titanium carbide, boron carbide, boron oxide, talc, silicon metal, carbon black, graphite, rare earth oxides, and zeolites.
