Abstract

A method of producing ceramic greenware, in particular a ceramic green film, having a ceramic powder component as the main ingredient and at least one organic solvent-free component as a secondary ingredient. To do so, the ceramic powder component is processed with the organic components initially to yield a highly viscous, solvent-free starting material which is then shaped by an extruder to form the greenware or green film.
