[Robin] starts with a demonstration of just how far a little bismuth depresses the melting point of tin solder — to about 135°. That allows plenty of time to work, and freeing leads from pads ...
and has been used to prepare low-melting typesetting alloys that need to expand to fill printing moulds. Bismuth trioxide is also the main ingredient in fireworks called dragon's eggs — those ...
They are used in the manufacture of solders, semiconductors, batteries, optical, and decorative products. Low melting alloys include bismuth, indium, lead, and tin metals and alloys. Bismuth is a low ...
Have you ever seen the science experiment (or magic trick ... even below the temperature that would usually cause it to melt. [Martin Thuo] at Iowa University used this property to make solder ...
