THALLIUM(I) BROMIDE Chemical Properties,Usage,Production
Crystal System
The space lattice of TlBr belongs to the cubic system, and its cesium chloride-type structure has a lattice constant of a=0.397 nm.
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
Uses
Thallium(I) bromide is used as Chemical reagents and pharmaceutical intermediates.
Uses
THALLIUM(I) BROMIDE is used for mixed crystals with thallium iodide for infrared radiation transmitters used in military detection devices.
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.
