Abstract

A porous, silicate, ceramic body, optionally with different colors, with a first density, can be sintered into a silicate, ceramic body with a second density, wherein the ratio of the first density to the second density is 2/5 to 98/100, and the three-point bending strength of the porous, silicate ceramic body with a first density, measured according to ISO 6872, is 25 to 180 MPa.
