- n. A white, crystalline, brittle, highly diamagnetic metallic element used in alloys to form sharp castings for objects sensitive to high temperatures and in various low-melting alloys for fire-safety devices. Atomic number 83; atomic weight 208.98; melting point 271.3°C; boiling point 1,560°C; specific gravity 9.747; valence 3, 5. See Table at element.

- n. One of the elements; a metal of a reddish white color, crystallizing in rhombohedrons. It is somewhat harder than lead, and rather brittle; masses show broad cleavage surfaces when broken across. It melts at 507° Fahr., being easily fused in the flame of a candle. It is found in a native state, and as a constituent of some minerals. Specific gravity 9.8. Atomic weight 207.5. Symbol Bi.
from The Century Dictionary and Cyclopedia
- n. Chemical symbol, Bi; atomic weight, 208; specific gravity, 9.6 to 9.8. A metal of a peculiar light-reddish color, highly crystalline, and so brittle that it can be pulverized.

- n. a heavy brittle diamagnetic trivalent metallic element (resembles arsenic and antimony chemically); usually recovered as a by-product from ores of other metals
I don't know, exactly what alloys you mean, but bismuth is common, and is heavier than lead in atomic weight.
The plant, which refines lead, silver, gold and bismuth, is blamed with causing dangerously high lead levels in the blood of more than 50% of the children living in its immediate vicinity.
The name bismuth is derived from the old German word wismut, meaning white metal, or meadow mines.
The salt represented in the last equation is sometimes called bismuth oxychloride, or bismuthyl chloride.
Only one Bolivian mine was a primary bismuth mine; in other countries the bismuth is a by-product of mining other metals.
This shews the danger of using white paint on the face, which is called bismuth, but is in reality white lead or cerussa.
If the neutral body be lighter than the medium, it exhibits the magnetic induction of iron with respect to polarity, but is nevertheless repelled; while if it be heavier than the medium, its direction is similar to that of diamagnetic bodies such as bismuth, but on the other hand exhibits the phenomena of attraction.
Water forms an appreciable number of hydrogen and hydroxyl ions, and very weak bases such as bismuth hydroxide are dissociated to but a very slight extent.
Briefly, the procedure involves the covering of the fingers with heavy salts such as bismuth or lead carbonate, in a thin, even film over the pattern area and then, by the use of the
Compounds of bismuth fused with cyanide of potassium in a Berlin crucible readily give a globule of bismuth which is recognised by its appearance and fracture.
