Potassium bromide (KBr) is an important material with wide applications in optical materials, pharmaceutical preparations, biomedical materials, nuclear fuels and catalysts.<\/p>\n
Structure: ionic crystal, cubic system.<\/p>\n
Appearance: colorless crystal or white powder.<\/p>\n
Density: 2.75 g\/cm3<\/p>\n
Melting point: 734\u2103<\/p>\n
Boiling point: 1435\u2103<\/p>\n
Solubility: 650 g\/L (20\u2103)<\/p>\n
Slightly hygroscopic. The color turns yellow when exposed to light. 1g of this product is soluble in 1.5mL water, 1mL boiling water, 250mL ethanol, and 4.6mL glycerol. Its aqueous solution is neutral.<\/p>\n
Easily soluble in water. The solubility in 100g water is 53.5g (0\u2103), 65.2g (20\u2103), and 104.0g (100\u2103).<\/p>\n
Its bromide ion can be replaced by fluorine and chlorine. It reacts with sulfuric acid to generate hydrogen bromide. Reacts with silver nitrate to form yellow silver bromide precipitate<\/p>\n
1. Photoelectric materials: Potassium bromide is used to prepare optical glass and optical fiber, and is applied to laser technology and communication technology.<\/p>\n
2. Chemical analysis: Potassium bromide is used as a chemical reagent to determine the bromine content, as a catalyst or auxiliary agent, to prepare standard solutions.<\/p>\n
3. Pharmaceutical manufacturing: Potassium bromide is used as a drug raw material in the synthesis process of various drugs.<\/p>\n
4. Photosensitive materials: Potassium bromide is used to make photosensitive films, developers, film thickeners, toners and color photo bleaching agents, etc.<\/p>\n
5. Pharmaceuticals: Potassium bromide is used to prepare sedative tribromo tablets to treat neurasthenia, neurological insomnia and mental excitement.<\/p>\n
6. Other applications: Potassium bromide is used to make special soaps, engraving and lithography, spectrophotometry and infrared transmission, etc.<\/p>\n
1. Store in a cool, ventilated warehouse. Keep away from fire and heat sources.<\/p>\n
2. The packaging must be sealed and not in contact with air. Prevent moisture. Store separately from oxidants and acids.<\/p>\n
3. Prevent sunlight exposure and isolate from fire and heat sources. In case of fire, sand and carbon dioxide fire extinguishers can be used to put out the fire.<\/p>\n","protected":false},"excerpt":{"rendered":"
