Common Compounds of Bismuth Bi -- EndMemo
WebMar 1, 2000 · Because of the density, a 40% bismuth compound contains only about half the volume ratio as a 40% barium sulfate compound. Since bismuth produces a brighter, sharper, higher-contrast image on an x-ray film or fluoroscope than does barium, it is commonly used whenever a high level of radiopacity is required. Compared with barium, … Bismuth compounds are compounds containing the element bismuth (Bi). Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are less toxic than derivatives of those lighter elements. See more At elevated temperatures, the vapors of the metal combine rapidly with oxygen, forming the yellow trioxide, Bi 2O 3. When molten, at temperatures above 710 °C, this oxide corrodes any metal oxide and even platinum.
