“…The appropriate selection of additives is especially important in case of colloidal processing [1], in methods like: slip casting [2], gelcasting [3,4], tape casting [5], and mechanical foaming [6]. The number of different organics needed in a shaping process ranges from two to eight.…”

The paper presents the analysis of thermal decomposition of selected organic additives, which are commonly used in shaping of ceramic materials by colloidal methods. Shaping of ceramics requires using different additives which then are burned out during sintering process. For this reason, the knowledge about thermal degradation of organics used, as well as decomposition products, seems to be very important from the application point of view. The analyzed substances were as follows: diammonium hydrocitrate, citric acid, ammonium salt of acrylic polymer, L-ascorbic acid, N,N,N 0 ,N 0 -tetramethylethylenediamine, and ammonium persulfate. The thermal analysis has been done on the apparatus coupled with mass spectrometer what allowed to observe what types of gasses are released to the atmosphere during heating. The obtained results showed important differences in thermal degradation of organic additives. It was possible to determine at what temperature regions harmful gases like N 2 O, NO 2 , or SO 2 are released from the organics and which additives can be treated as environmentally friendly.

“…The slurry was homogenized by ball milling for 12 h at a very low speed of 40 rpm, which was an effective way to remove the air contained in the slurry. 10 It is well known that in the tape casting process, the support or carrier sheet are of prime importance, because the wetting ability of the slurry with the support is essential for a good adherence. However, strong adherence between the support and the dried tape results in difficulty in stripping the tape from the support.…”
