| Abstract: | The highly exothermic reaction between carbon fibres and molten silicon, which is the basis of SiC-Si composite production, was investigated using a Setaram 2000 K thermoanalyser. DTA curves were recorded in 1.3 Pa vacuum and up to 1770 K, i.e. under the conditions of composite production. The results allowed calculation of the heat of the reaction, which ranged from 91 to 115 kJ/mol. |
