ANALYSIS OF PHASE DIAGRAM OF Sn - P - As SYSTEM
The T-x diagram of polythermal section Sn 4As 3 — Sn 4P 3 was constructed by differential thermal analysis. The section Sn 4As 3 — Sn 4P 3 is partially pseudo binary and it can carry out a triangulation of ternary Sn — P—As diagram at temperatures below the solidus line. The solid solution decay is possibly in the range of compositions containing more than 70 mol. Sn 4P 3, according to the sintektik scheme α↔ L 1 + L 2.
