A PROCESS FOR THE TREATMENT OF AT LEAST ONE THREE-DIMENSIONAL GREEN BODY
The present invention relates to a process for the treatment of at least one three- dimensional green body (GB), wherein the at least one three-dimensional green body (GB) comprises an inorganic powder (IP) and a binder (B), the binder (B) comprising as component (b1) at least one polyoxymethylene (POM). In this process, 0.01 to 5.0% by weight of anhydrous oxalic acid, based on the total weight of the at least one three- dimensional green body (GB), are provided with which the at least one three-dimensional green body (GB) is treated at a temperature (T1) < 140 °C in the presence of an inert gas. The present invention further relates to a three-dimensional brown body (BB) prepared by this process and to a three-dimensional sintered body (SB) prepared from the three-dimensional brown body (BB). Furthermore, the present invention relates to anapparatus, in which this process is carried out.
