Description
Bismuth is a radioactive chemical element in the periodic table with the symbol Bi and atomic number 83. It is usually referred to as “Wismut” in German, but the name bismuth has also been used officially in this country since 1979. The radioactivity of natural bismuth is so low that it was not detected until 2003.
Bismuth is a shiny reddish metal that is brittle when technically pure (very pure bismuth is plastic, whereby the smallest amounts of copper lead to embrittlement). It has a rhombohedral crystal structure with very densely packed double layers. Bismuth is one of the few non-toxic heavy metals, has the strongest Hall effect of all metallic elements, a high electrical resistance and also has the strongest diamagnetic property – apart from superconductors and pyrolytic graphite – i.e. it migrates out of an externally applied magnetic field.

* This is a recommendation based on our experience with these materials in our sputter guns. Rates are based on non-bonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or lower depending on the material.
