Pertitectic Diagram
· Silver and Platinum have different melting points and a Peritectic reaction. |

·
Silver
melts at 961 C, and Platinum melts at 1769 C. The Peritectic invariant
reaction occurs at 1200 C, with the peritectic composition of Ag- 52%
Pt. (Alloy 1)
· The invariant reaction converts a liquid and a solid to a single solid phase: |
