Rhenium for Scientific Instrument Filaments | Properties ...

About Pure Rhenium Pure rhenium is an important material for many scientific instrument filaments, as well as other electron and ion source filaments. Most rhenium naturally occurs in porphyry copper deposits. Hydrogen reduction is used to convert ammonium perrhenate to pure rhenium powder. The pure rhenium powder is pressed and sintered into ingots.

The number of electrons in each of rhenium's shells is 2, 8, 18, 32, 13, 2 and its electron configuration is [Xe] 4f 14 5d 5 6s 2. The rhenium atom has a radius of 137 pm and a Van der Waals radius of 217 pm. Rhenium was discovered and first isolated by Masataka Ogawa in 1908. In its elemental form, rhenium has a silvery-white appearance.

The ion source is the heart of the mass spectrometer. In the ion source, ions are created from gas-phase neutral sample molecules, or preformed ions are extracted from solu-tions, and then sent into the mass analyzer of the instrument. The electron ionization (EI) source was the first source widely used for organic mass spectrometry (MS), and

Rhenium | Re - PubChem

Rhenium (Re), the last naturally-occurring element to be discovered, was discovered in Germany in 1925. The process was so complicated and the cost so high that production was discontinued until early 1950 when tungsten-rhenium and molybdenum-rhenium alloys were prepared.

We recently investigated the feasibility of a rhenium wire source for preventing restenosis. Dosimetric measurements on a 0.5 mm-diameter metallic rhenium source showed that it could deliver the necessary doses of 15–18 Gy to vessels with diameters up to 6 mm (Häfeli et al., 1999). Further reasons for chosing rhenium was its good ...

Rhenium - Wikipedia

Tungsten-rhenium wire was originally created in efforts to develop a wire that was more ductile after recrystallization. This allows the wire to meet specific performance objectives, including superior vibration resistance, improved ductility, and higher resistivity. One application for the tungsten-rhenium …
