It is, in many ways, an impressive metal.
The purity is 99,99 %.
isotope 290
This metal is mainly used as an alloying metal for the production of low-melting alloys (lead substitute).
Furthermore this metal has very strong diamagnetic properties.
It also has a very helpful property in the manufacture of casting moulds: by increasing the volume during the transition from the liquid to the solid aggregate state, the sharpness of the contours is influenced in the best possible way.
Bismuth or bismuth (obsolete also: bismuth) is a chemical element with the element symbol Bi and atomic number 83.
In the periodic table it is in the 5th main group or nitrogen group.
There is no known stable isotope.
However, the extremely low radioactivity of the naturally occurring Bi is of no practical significance
Bismuth is one of the few relatively (see below) non-toxic heavy metals, has the strongest Hall effect of all metallic elements (which is typical for a semimetal as well as the poor electrical conductivity of the purest bismuth) and also has the strongest diamagnetic property - apart from superconductors and pyrolytic graphite.
This means that it is pressed out of an externally applied magnetic field
Bismuth chloride oxide (BiOCl) is used as a silvery white pearlescent pigment in cosmetics.
Bismuth vanadate is used as a highly weather-stable greenish yellow pigment and is used, for example, in high-quality paints, emulsion paints for facades, plastics and printing inks
Bismuth is also used as a catalyst in the chemical industry
