描述 产品目录编号 104907 Replaces PX1378 同义词 Hydrobromic Acid Potassium Salt 概述 Potassium bromide is transparent from the near UV to long wave IR wavelengths. In IR-spectroscopy, solid samples which are difficult to melt or dissolve in any suitable IR-transmitting solvent, are analyzed by grinding with Potassium bromide powder, and pressing into a disc. This procedure has a high quality demand of the used potassium bromide. Potassium bromide Uvasol® is adjusted to a mean particle size of 150 μm. This is sufficient for the preparation of perfectly good pellets without the need for further pre-treatment and the associated risk of contamination. It also retains its powdery form over a period of years if stored in an air-tight condition. Its physical suitability for pelletising is checked by a special application test and its chemical purity established by full spectrum FT-IR analysis. 产品信息 CAS号 7758-02-3 EC号 231-830-3 Hill配方 BrK 化学配方 KBr Molar Mass 119.00 g/mol HS代码 2827 51 00 理化信息 沸点 1435 °C (1013 hPa) 密度 2.75 g/cm3 (20 °C) 熔点 730 °C pH值 5.5 - 8.5 (50 g/l, H₂O, 20 °C) 蒸汽压力 1.3 hPa (795 °C) 容积密度 900 - 1000 kg/m3 溶解度 650 g/l GHS安全信息 危害性图示
