Bismuth is a heavy metal that has similar qualities to lead, it also has a low melting point and a low level of electrical and thermal conductivity. Bismuth is also classed as diamagnetic, meaning that it is repelled by a magnetic field.
When combined with other metals, bismuth helps to create low melting point alloys that are used in fire extinguishers and detectors. Because of their similar qualities, bismuth can also be used as a replacement for lead in some applications.
Average particle size:
Pure bismuth 10micron +. It is also available in coarser lump material.
Qualities:
Pure bismuth is the most diamagnetic of all metals, and thermal conductivity is lower than any metal except mercury providing high electrical resistance.
Applications:
Bismuth is a popular substitute for lead in radiation shielding blankets and is used as an alloying element in lead-based low melting point alloys. Bismuth is also commonly used in thermoelectric materials and infrared spectrometers.
