Glass-forming region in the Cd-Ge-As ternary system

In the Cd-Ge-As system, bulk glassy samples can be prepared by quenching of the melt for certain compositions. The glass-forming region is not very large. It includes the pure CdAs₂ compound, the strongest tendency to form a glass is at CdGe_0,3As₃. The characteristic phase transition temperatures for some glasses were determined by DTA. The studies also show that all these glasses recrystalize on heating. After melting and slow cooling they solidify as polycrystals.
