摘要：

Based on the critically assessed B-Si phase diagram, one alloy in the Si-rich side was selected and the temperature of the eutectic reaction L <-> (Si) + SiB6, was measured to be 1636 K by means of DSC. Using a regular substitutional model for the liquid phase, the B-Si system was reassessed and extrapolated to higher-order systems. Thermodynamic description for the B-C-Si system was developed based on critically reviewed experimental data. The calculated phase diagrams were in good agreement with available experimental data.
