Fabriion of Reaction Bonded Silicon Carbide (RBSC) Using Boron Carbide …
In our previous work was also established that boron carbide directly reacts with liquid silicon and serves as carbon source in the reaction bonded boron carbide composites. In the present work we have coined these two features in order to fabrie RBSC composites with decreased amount of the residual silicon and using boron carbide as an alternative source of free carbon instead carbon

Reproducibility of diffraction patterns was examined on the prepared specimens to estimate a critical particle size required for reliable XRD analysis. Relationships of SiC amounts vs. intensity ratios of SiC to internal standard silicon were compared among specimens with different sized SiC and among different lines of SiC and silicon.
