THALLIUM(I) BROMIDE

Description

Thallium bromide is a yellow-white solid and hygroscopic. It is similar to silver bromide. It gets darker when light shines on it. It is very toxic, like all thallium compounds. It does not dissolve in water. Thallium bromide is used in gamma ray and x-ray detectors and also in semiconductors. Prolonged period of exposure to thallium compounds has been reported to cause adverse health effects such as joint pain, severe pain in legs, loss of appetite, fatigue, and albuminuria.

Chemical properties

THALLIUM(I) BROMIDE is yellow crystalline powder

The Uses of THALLIUM(I) BROMIDE

THALLIUM(I) BROMIDE is used for mixed crystals with thallium iodide for infrared radiation transmitters used in military detection devices.

The Uses of THALLIUM(I) BROMIDE

Thallium(I) bromide is used as Chemical reagents and pharmaceutical intermediates.

What are the applications of Application

Thallium(I) bromide is a compound semiconductor used in room temperature X- and gamma-ray detectors and blue sensitive photodetectors

Production Methods

Single crystals are synthesized by the Stockbarger method after putting high grade sources into a well dried alumina crucible. The crystal is easy to process according to its nonfragile character.

Safety Profile

Poison by ingestion and subcutaneous routes. Reacts violently with Na, K. When heated to decomposition it emits very toxic fumes of Brand T1. See also BROMIDES and THALLIUM COMPOUNDS.

Purification Methods

Thallous bromide (20g) is purified by refluxing for 2-3hours with water (200mL) containing 3mL of 47% HBr. It is then washed until acid-free, heated to 300o for 2-3hours and stored in brown bottles. It solubility in H2O (w/w) is 0.034% at 0o, 0.048% at 20o, and 0.204% at 100o. [D.nges in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 870 1963]. POISONOUS.
