Atomic No. 83 Bi Bismuth

About Bismuth

Bismuth is a metal with atomic number 83 whose chemistry is dominated by the +3 oxidation state. Its compounds include bismuth telluride for thermoelectric devices and bismuth germanate for radiation detection. Bismuth stannate is investigated in semiconductor photocatalysts, including compositions designed to degrade organic contaminants under illumination. Layered bismuth titanate exhibits ferroelectric and piezoelectric behavior, supporting research into electronic ceramics and sensors that operate at elevated temperatures.
