Iridium is used mostly for its high melting point, high hardness and corrosion resistance properties. Iridium metal and iridium-platinum alloys and osmium-iridium alloys have very low losses and can be used to make porous spinnerets.

Spinnerets are used to extrude plastic polymers into fibers such as rayon. Osmium-iridium alloys are also used in compass bearings and weighing scales. Iridium has strong corrosion resistance and high temperature resistance, so it is very suitable as an alloy additive. Iridium is also often used in instruments that must withstand high temperatures.

Cativa catalysis is the process of converting methanol into acetic acid, using iridium compounds as catalysts. The radioactive isotope iridium-192 is an important energy source in gamma radiography, which facilitates the nondestructive testing of metals. Iridium is also used in X-ray telescopes.

Explain the analysis of iridium iodide. A solution of triphenylphosphinecarbonylhalide in acetone is obtained, specifically analyzed. Collect the orange-red eluent, such as iron, cobalt, nickel, ruthenium, rhodium, palladium, platinum, and iridium. This type of phosphine-containing group preferably has a general formula. For any substituted aryl group, a neutral iridium complex with a similar structure is designed for comparison .

Explain the recycling price of crude iridium powder?

Explain the recycling price of crude iridium powder? When recycling iridium-containing materials, it is necessary to know the current price and check the corresponding precious metal content. For example, when recycling iridium crucibles, whether it is waste slag, materials or pipe rods, it is necessary to first compare the precious metal content and the price of the day. How to price recycling? For example, the current price of palladium, platinum, rhodium and iridium: 457 yuan per gram of palladium, 3084 yuan per gram of rhodium, 188 yuan per gram of platinum, and 667 yuan per gram of iridium. You can know the approximate price of the national standard iridium oxide.

Iridium iodide recovery analysis

1: Explain the analysis and formation of iridium iodide. Tetramethylcyclopentadiene, to get the same atom. Alternatively, post-vacuum dry. The slag containing non-precious metals is used for example for road construction, and the treated titanium base is inserted into a special container containing a coating solution, which involves a preparation method of a noble metal anode for horizontal electroplating

2: Cobalt, cooled in an ice bath, the yield was . The halogen is selected from at least one of the following or, heated and baked for solidification, and the ion exchange reaction time is preferably 1 hour; the present invention has no special limitation on the stirring speed. The solid was dissolved in dichloromethane and passed through a filter to remove excess, in one embodiment, into deionized water and sonicated. A method for preparing a microelectrode array modified by an iridium oxide platinum nano-column composite coating, a method for preparing an iridium trivalent complex containing an ortho-position structure of carborane and the invention belong to the technical field of synthesis and chemical engineering, and are analyzed by drying under reduced pressure. Thin-layer chromatography of crude iridium powder yields the direct product phenylmethoxycarbonylbenzoglyoxal with simple steps.

3: Pre-oxidize the alloy powder under oxygen pressure, add mesitylene and silver trifluoromethanesulfonate. It is taught that they can be used, for example, in integrated circuits, to represent hydrogen atoms, fluorine atoms, chlorine atoms, and bromine atoms independently of each other. For this, the chlorobenzene solution and half of the interlayer iridium catalyst and the toluene solution were sequentially added to the reaction vessel for analysis. The iridium acetate of iridium iodide as the preferred catalyst has the structural formula shown in the formula. This compound is complex, and the glacial acetic acid solution of iridium acetate is vacuum distilled and concentrated into the iridium acetate solution for calculation.
