Abstract
Five phases exist in the system Co-Si: Co3Si, alpha- and beta -Co2Si, CoSi and CoSi2. The phases alpha -Co2Si and CoSi could be prepared by chemical t ransport with iodine as transport agent in the temperature range between T- 1 (700 degreesC) and T-2 (900 degreesC). In a attempted systematic clarific ation of the chemical transport reactions of all phases in the system, the effective transport equilibria were determined. Thermodynamic data show sat isfactory agreement between calculation and experiment.
