Introduction of Iridium (Ir)

Iridium, represented by the symbol Ir, is a white, brittle, very arduous, element. The number of atomic number 77. it's one in all the transition parts of the table.

Introduction to iridium (Ir) metal- Discovery, properties and uses of iridium (Ir) metal

Discovery of Iridium (Ir) metal

Iridium was discovered by Brits chemist Smithson Tennant in 1804 and was named for the iridescent nature of a number of its compounds.

Properties of Iridium (Ir) metal

Iridium is very inert with chemicals, resisting even the action of acid. In its chemical compounds, it forms powerfulness and powerfulness salts. it's a very rare metal, ranking 77th so as of abundance of the weather in Earth’s crust.

The mass of atomic number 77 is 192.22. It melts at concerning 2446°C (about 4435°F) and boils at concerning 4428°C (about 8002°F).

Its relative density is twenty-two.6, creating atomic number 77 over doubly as dense as lead. atomic number 77 and metallic element area unit along thought-about to be the densest elements; their densities area unit, therefore, shut on be nearly indistinguishable.

Occurrence of iridium (Ir) metal

Iridium is found in sediment deposits alloyed with atomic number 78 as platiniridium and with the metallic element as iridosmine. atomic number 77 is employed primarily as AN alloying material for platinum; the alloy, that contains concerning ten p.c atomic number 77, is way more durable than pure atomic number 78.

Platinum-iridium alloys containing larger percentages of atomic number 77 area unit utilized in creating preciseness instruments, surgical tools, pen points, and normal weights and lengths.

Uses of iridium (Ir) metal

The main uses of Iridium (Ir) metal are as a hardening agent for noble metal alloys. With metallic element, it forms associate alloy that's used for tipping pens and compass bearings. Ir is employed in creating crucibles and different instrumentality that's used at high temperatures. it's conjointly wont to create industrial electrical contacts.
