| Abstract: | In order to deal with the shake-out of ceramic mold castings, it is first nee essary to understand the sintering mechanism. For this purpose, an investigation of the effect of the chemical composition and grain distribution of the ceramic material and the effect of the amount of binders and additives on the degree of sintering was carried out by scanning electron microscopy, polarizing electron microscopy and X-ray diffraction device. The microstructure of the mold, the residual strength of the mold after high temperature processing, and the final shake -out behaviour were tested under different tachnical formations and compared with each other. Some preferential formations with improved collapsibility are proposed. |
