Can woodworking handheld metal detectors detect iridium?

Metal detector functions are divided into: 1) Full metal detector: can detect all metals such as iron, stainless steel, copper, aluminum, etc.

The detection accuracy and sensitivity are relatively high, stable and reliable. 2) Ferrometal detector: It can only detect ferrous metal, commonly known as needle detector.

The detection accuracy and sensitivity are low, and it is easy to interfere. 3) Aluminum foil metal detector: It can only detect ferrous metals, but when detecting products with aluminum foil packaging, its detection accuracy and sensitivity are still high.

Handheld metal detectors for woodworking are ferrous metal detectors, so iridium should not be detectable.

Iridium is a platinum group element. Platinum series elements exist almost entirely in a elemental state and are highly dispersed in various ores, such as primary platinum ore, nickel-copper sulfide ore, magnetite, etc. Platinum elements almost invariably coexist together to form natural alloys.

In platinum-containing ores, platinum is usually the main component, while the rest of the platinum-series elements must be chemically analyzed because of their small concentrations. Since osmium, iridium, palladium, rhodium, and ruthenium all form the ore together with platinum, they are all found in residues after platinum has been extracted from platinum ore.

With a handheld metal detector, broken nails can be detected, like the GC-1002's handheld metal detector, which can detect nails 1-5 cm deep in wood. You can find it on **, a lot.

Physical properties: Silvery-white metallic, hard and brittle. During thermal processing, as long as it is not annealed, it can be expanded into filaments and thin sheets; Once annealed, it loses its ductility and becomes hard and brittle.

Density gram cm3. The melting point is 2410 40, and the boiling point is 4130. Face-centered cubic crystals.

Chemical properties: Chemically stable. Insoluble in acids. slightly soluble in aqua regia; It is slightly attacked by molten sodium hydroxide, potassium hydroxide and sodium dichromate. There is a strong tendency to form coordination compounds. The main valencies are +2, +4, +6.

It is not uncommon to encounter ** jewelry mixed with other metals in the acceptance of counter business, but it is indeed a new type of adulterated jewelry mixed with iridium, ruthenium and osmium in ** jewelry. Because of iridium

Yes, the doping of metal iridium is a recent counterfeiting practice, due to the high density of iridium metal, which is very close to **, some of the previous methods of identifying the color are now not applicable.

For users, there are now two ways to invest, 1 is to buy paper; 2 is to purchase gold bricks with unified national specifications; If you buy a BRICS investment, you can buy it from ** (usually a big shopping mall) to **go**. If it is remelted**, many times the state does not accept it. This is because the detection of iridium metal is more difficult.

You buy iridium-doped**You make a lot of money, and iridium is much rarer than **!

It mainly depends on what method you use to detect. This kind of false reference is mainly not easy to detect by density measurement method. In the past, it was not easy to find with a touchstone test.

But in fact, there is a difference in color and hardness. Soon there will be new ways to solve such problems. What is fake is always fake.

Now **** is 361 yuan per gram, iridium's ** is 397 yuan per gram, add 397 yuan of iridium to ** and sell**361 yuan, what is this operation?

Have you ever seen someone else** use ** to participate in the fake and sell it at a **price?

I don't understand how there is metal in food. If it is a metal detector for Tanbao, you can look at Hefei Chuangzhao, but when you buy it, they must provide some detection evidence.

Yes, but you'll want to buy one that's a little more sophisticated.

We have it in our laboratory, and it is not easy for individuals to buy it when they order it from a chemical reagent factory.

You're a ** person.。。

Check out the chemical store.

Chemical plants are definitely dropping.

Just remember that the IR-OS alloy is an iridium pen nib.

Iridium element symbol IR, atomic number 77, atomic weight, peripheral electronic configuration 5d76s2, is located in the sixth period group . Atomic radius picometer, first ionization energy 885kj mol, electronegativity, main oxidation number +3, +4, +6. Silvery-white metal, very hard, brittle, and has good ductility when heated.

Density, melting point 2410, boiling point 4130. The chemical properties are very stable and the corrosion resistance is very strong at room temperature. Insoluble in acids, slightly soluble in aqua regia and molten alkali.

It was discovered in 1803 by the Englishman Thornett and others. Pure iridium is used in aircraft spark plugs, and is also used in the manufacture of scientific instruments, thermocouples, resistance wires, tap nibs, high-temperature resistant alloys, and catalysts. The international standard meter ruler is made of platinum-iridium alloy.

It is mainly found in osmium-iridium ore and platinum ore.

It is harmless to humans.
