Processing of advanced ceramic components by pressure casting usually fell through because of insufficient demoulding. CIC Ceramic Institut Clausthal GmbH developed an inorganic additiv which eliminates this disadvantage. Large-volume components from oxidic slurries can be realized in this manner. Al2O3 -slurries can be ordered by Nabaltec AG. They can be pressure cast and demoulded after casting without any difficulty.
