The phase diagram of the Ba-Si system

Description

The phase diagram of the Ba-Si system has been completely revised from a thermal point of view. All the already-known intermediate phases have been confirmed: Ba2Si (Co2Si type), Ba5Si3 (Ba5Si3 type), BaSi (CrB type), Ba3Si4 (Ba3Si4 type) and BaSi2 (BaSi2 type). Save for Ba5Si3, which forms peritectically, all other compounds melt congruently. The five eutectic compositions occurring in the system are at 11, 40, 52.5, 60 and 83 at.% Si, respectively.
