| | THALLIUM(I) BROMIDE Usage And Synthesis |
| 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 for mixed crystals with thallium iodide for infrared radiation transmitters used in military detection devices. | | Uses | Thallium(I) bromide is used as Chemical reagents and pharmaceutical intermediates. | | 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.
