Název v původním jazyce

Starch as a pore-forming and body-forming agent in ceramic technology

Popis výsledku v původním jazyce

Wheat and corn starch can be used fotr the preparation of porous alumina ceramics via the SCC (starch consolidation casting) process, resulting in porosities ranging from>20% to approx. 50% (using nominal starch contents of 10-50%, v/v) with open porosity dominating (Closed porosity <6.5%). The character of porosity and the shape of the pores corresponds to the starch granules used, but the pore size is determined by a complex interplay between starch swelling (during the body-forming step) and pore shrinkage (during sintering of the ceramic). Typically, for low starch contents (e.g. nominal starch contents of around 10%, v/v) starch swelling is a singnificant effect, and the pores after sintering are larger than the size of the starch granules. For higher starch contents swelling is constrained (by limited space and/ or water availability), and the matrix shrinkage during sintering overcompensates the swellint effect, so that the final pores in the ceramic can be significantly smaller
