Abstract
A composition which is suitable for extrusion molding comprises a) a ceramic-forming material, and b) a cellulose derivative that has a median particle length of from 110 to 300 micrometers. Advantageously a cellulose ether is used that has been obtained by providing a moist cellulose derivative having a moisture content of from 35 to 90 percent, based on the total weight of the moist cellulose derivative, and drying-grinding the moist cellulose derivative in a gas-swept impact mill to a median particle length of from 110 to 300 micrometers.
