BISMUTH TELLURIDE Chemical Properties,Uses,Production

Chemical Properties

Bismuth telluride is a gray or black crystalline solid or gray powder.

Uses

Bi2Te3, along with Sb2Te3 and other structurally analogous semiconductors, is widely regarded as one of the best materials for room-temperature thermoelectric devices. Bismuth(III) telluride is a key component of thermoelectric materials that have reached ZT values as high as 2.4 at room temperature.

Uses

In electronics as semiconductor.

General Description

Gray or black hexagonal platelets with a metallic luster or gray powder. Mp: 586°C. Density: 7.8 g cm-3. An alloy of two metallic elements.

Reactivity Profile

BISMUTH TELLURIDE may emit toxic fumes of tellurium when heated to decomposition. Incompatible with strong oxidizing agents such as nitric acid or bromine, chlorine or fluorine. Moderate fire hazard by reaction with such materials. May react with strong acids to evolve toxic gases; may react slowly with water to evolve toxic gases. Slight explosion hazard with moisture.

Hazard

Toxic.

Potential Exposure

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.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Shipping

UN3284 Tellurium compound, n.o.s., Hazard Class: 6.1; Labels: 6.1—Poisonous materials, Technical Name Required.

Incompatibilities

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.
