What are uses for iridium?
Iridium is a corrosive resistant element even when subjected to high temperatures of around 2000 deg centigrade..Its a rare earth element atomic number 77. Corrosion and heat resistance makes iridium an important alloying agent. Certain long-life aircraft engine parts are made of an iridium alloy and an iridium-titanium alloy is used for deep-water pipes because of its corrosion resistance.[10] Iridium is also used as a hardening agent in platinum alloys. The Vickers hardness of pure platinum is 56 HV while platinum with 50% of iridium can reach over 500 HV. Iridium has been used in the radioisotope thermoelectric generators of unmanned spacecraft such as the Voyager, Viking, Pioneer, Cassini, Galileo, and New Horizons. Iridium was chosen to encapsulate the plutonium-238 fuel in the generator because it can withstand the operating temperatures of up to 2000 °C and for its great strength.[
What does 10 percent IRID mean when stamped into the metal in an old ring?
Usually this marking is used on PLATINUM a lot. It is used when jewelry is 90% PLAT and 10% IRID. IRID is the abbreviation for IRIDIUM (a silver looking alloy).
What is the number stamping for platinum?
The oldest and most common jewelry alloy for platinum is 90% platinum, 10% iridium. You'll see various stamps, the most common maybe is 10% Ir Plat or something like that. Occasionally it's all spelled out, too. A newer alloy is 950 platinum, where the other 50 is usually cobalt. Usually that is stamped 950 Plat. or 950 Platinum. Those are the two most common, anyway.
Which are any 10 metals?
rhodium, platinum, gold, ruthenium, iridium, osmium, palladium, rhenium, silver, and indium, iron, nickel, copper, lead, mercury, calcium, strontium, titanium etc.
What is platinum's family name?
AnswerIt is a transitional metal in period 6, group 10 of the periodic table.
Weight definition unit and instrument?
In the SI the unit of mass is kilogram: the mass of of a cylinder (height=diameter= 39,17 mm) made from 90 % platinum and 10 % iridium. The instrument to measure mass is a balance.
What does Pl900 mean on a ring?
The marking "PL900" on a ring indicates that the metal is composed of 90% platinum and 10% other metals, such as iridium or ruthenium, which are often added to enhance durability and strength. Platinum is a precious metal known for its rarity and resistance to tarnish, making it a popular choice for fine jewelry. The "900" signifies the purity level, reflecting the high quality of the platinum used in the ring.
What are the platinum group metals?
The platinum group metals (abbreviated as the PGMs; alternatively, the platinoids, platidises, platinum group, platinum metals, platinum family or platinum group elements (PGEs)) is a term used sometimes to collectively refer to six metallic elements clustered together in the periodic table. These elements are all transition metals, lying in the d-block (groups 8, 9, and 10, periods 5 and 6). The six platinum group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits
