Abstract : New ceramic materials with dispersed phases within a silicium carbide matrix in the Ti-Si-C chemical system seem very attractive to improve toughness properties. Deposition domains of SiC-TiC and SiC-Ti3SiC2 are determined by thermodynamic calculation in the Si-Ti-C-Cl-H chemical complex system, and presented in the coordinate system of the variance parameters. The representation of these domains in the coordinate system of the initial gas mixture is then easily deduced whatever the bearing molecule considered. For a given composition of the gas mixture at equilibrium the ratio between the deposited phases can present very large variations according to the initial gas-mixture.
