Potassium perrhenate is a chemical substance composed of potassium ions (K+) and rhenium oxide ions (ReO4-). The weight of each molecule is about 289.31 g\/mol.<\/p>\n
Molecular formula: KReO4<\/p>\n
Molecular weight: 289.3029<\/p>\n
Appearance: white crystalline powder<\/p>\n
Density: 4.89g\/cm3<\/p>\n
Melting point: 550\u2103<\/p>\n
Boiling point: 1360~1370\u2103<\/p>\n
Refractive index: 1.643<\/p>\n
Crystal system: tetraclinic crystal<\/p>\n
Solubility: slightly soluble in water, poorly soluble in ethanol. The solubility varies greatly with temperature. At 0\u2103, the solubility is 0.36g, and at 50\u2103 it is 3.3g. If KCl or other potassium salts are added, the solubility is even lower.<\/p>\n
Potassium perrhenate is produced by dissolving potassium hydroxide or potassium carbonate with perrhenic acid.<\/p>\n
1. Used for the preparation of pure rhenium;<\/p>\n
2. Used as an analytical reagent (spectral analysis);<\/p>\n
3. Used as an oxidant.<\/p>\n
Our products implement the most stringent quality management system, and there are strict inspection standards for incoming materials, processes, final inspections, and factory inspections. Strict isolation measures will be adopted for unqualified processing to prevent unqualified products from flowing into the next process. Samples will be provided to customers according to customer requirements for re-inspection.<\/p>\n
Inner vacuum packaging, outer carton packaging.<\/p>\n
Potassium perrhenate should be sealed and stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30\u2103 and the relative humidity should not exceed 80%. The packaging should be sealed. It should be stored separately from flammable (combustible) materials and reducing agents, and should not be mixed. The storage area should be equipped with appropriate materials to contain leaks.<\/p>\n","protected":false},"excerpt":{"rendered":"
