摘要
The invention relates to a method for manufacturing a chemically bounded ceramic by reaction between one or several pulverulent binding agents and a liquid which reacts with these binding agents, wherein the ceramic product also can include one or several aggregates, which essentially do not take part in the chemical reactions. An amount of pulverulent material consisting of said binding agent and possible aggregate material is blunged in said liquid so that all powder grains are caused to effectively contact the liquid. The obtained slurry or slip is drained so that the main part of surplus reacting liquid is removed. An amount of the mixture of powder and reacting liquid which still exist to some extent in the mixture is applied in a mould cavity, and additional liquid is removed insitu in the mould cavity before the product is caused to harden through reaction between said binding agent and remaining liquid. The invention also relates to a tool for the carrying out of the method, comprising a preferably exchangeable working part (5) consisting of a solid porous material.
