It is used primarily to harden platinum and palladium in alloys. Ruthenium (Ru), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, used as an alloying agent to harden platinum and palladium.Silver-gray ruthenium metal looks like platinum but is rarer, harder, and more brittle. Ruthenium Palladodymite Hongshiite Comments: Palladodymite (light gray, in two small grains), hongshiite (pale creamy grayish, tarnished brownish) in massive ruthenium. Buy Black Ruthenium Coins online from eCoins, Inc.
Structural color from Ru-coated AAO nanostructures.
The elements in this group are named after the best known member of the group, platinum. It has only one valence electron. Like many dioxides, RuO 2 adopts the rutile structure. Ruthenium(IV) oxide is the inorganic compound with the formula Ru O 2.This black solid is the most common oxide of ruthenium.It is widely used as an electrocatalyst for producing chlorine, chlorine oxides, and O 2 catalyst is ruthenium(IV) oxide. Polished section (from microprobe analysis) in reflected light. Ruthenium Powder We will buy your Ruthenium Powder! This button of pure solid ruthenium was created by the easiest known method--melting ruthenium powder in an argon-arc furnace.

Brilliant structural colors are found from the Ru-coated AAO nanostructures, in which the color display covers the full visible range. Depending on the Ru thickness and the AAO dimensions, the Ru nanoarchitectures could be completely changed (tubular-type or wire-type Ru nanostructures), and the corresponding optical properties are critically affected. It is extracted from platinum metal ore concentrates and isolated as a gray powder or a sponge using chemical techniques.
Reflectance spectra and photographs according to different AAO thicknesses (110, 170, 230, and 280 nm) for the Ru thickness of (a) 10 nm, and (b) 20 and 40 nm. One such material, ruthenium red, is a dye used to stain negatively charged biomolecules such as nucleic acids in microscopy.

Here, we systematically investigate optical behaviors of ruthenium (Ru)-coated nanoporous anodic aluminum oxide (AAO) nanoarchitectures in the visible and near-Infrared (NIR) regions, where they are fabricated by an atomic layer deposition (ALD) process. Jewelry is often ruthenium-plated when a dark, pewter-colored shine is desired. Ruthenium will dissolve in fused KOH to give K 2 [RuO 4]. Ruthenium compounds also have some nice optical and electronic properties.
The periodic table is a chart that shows how chemical elements are related to … Ruthenium crystallizes in the hexagonal close-packed arrangement, is lustrous, and is silvery in color.
