Composition
Bi 60, Sn 40 (wt%)
Standard codes
Reaction
Processing
Small casting in alumina crucible - air cooled.
Applications
Educational alloy - low melting point allows easy and safe use for students.
Sample preparation
Standard polishing techniques.
Technique
Scanning electron microscopy (SEM) in secondary electron imaging (SEI) mode
