| 摘要 |
The present invention relates to a method for the production of a chemically bonded ceramic product by a reaction between one or several pulverulent binding agents as well as a liquid reacting with said binding agents. The ceramic product can also include one or several aggregate materials, which essentially do not participate in the chemical hardening reactions. According to the invention a powder body is compacted, which comprises said binding agent(s) and possibly aggregate materials without an addition of said liquid, by subjecting, before said raw compact is impregnated with said liquid, said powder body to such a high external pressure that a thoroughly integrated raw compact is obtained, in which the filling density has increased to at least 1.3 times the initial filling density, which is defined as that filling density, which is obtained by shaking, vibrating and/or carefully packing the loose powder in a container. |
