Bismuth telluride is used in thermoelectric
cooling, power generation, semiconductor manufacture;
pharmaceuticals; medical therapy; cosmetics.
Exposure involves those working in “Silicon Valley” and
similar locations around the world. An alloy of two metallic
elements that are sometimes doped with SeS. The SeS
dopant alters the electrical properties, but has too low a
concentration to affect the chemical properties.
UN3284 Tellurium compound, n.o.s., Hazard
Class: 6.1; Labels: 6.1—Poisonous materials, Technical
Name Required.
Reacts with acids forming toxic gases.
Incompatible with oxidizers (chlorates, nitrates, peroxides,
permanganates, perchlorates, chlorine, bromine, fluorine,
etc.); contact may cause fires or explosions. Keep away
from alkaline materials, strong bases, strong acids, oxoacids,
epoxides. Toxic and flammable gas may slowly
evolve from contact with moisture.
