Where is platinum found? What are the primary uses of platinum? What is the price of platinum? Is platinum a precious metal like gold and silver? Platinum is a periodic table element with the atomic number 78 and the atomic mass 195. It is a very uncommon element found in the Earth’s...
The paper presents the results of investigation the influence of rhodium as an alloying element on the mechanical properties of platinum. A short-term and tensile strength were tested, at room and high temperatures, and also sliding rate and time to the destruction of the Pt-Rh system alloys ...
Platinum is a very rare metal, occurring at a concentration of only around 0.005 ppm in the Earth's crust. Pt ( Fig1. A 3-mm cubic crystal of platinum, Pt.) is often found as the native element and as alloys with the other Pt-group elements and Fe mostly. Most often the native P...
A choice of the supports was determined by their various chemical composition and structure/texture parameters leading to the different metal鈥搒upport interactions and various location of platinum. N2 adsorption/desorption measurements, XRD, 27Al MAS NMR, and TOF-SIMS techniques were applied for the...
Platinum What is Platinum Platinum (pronunciation PLAT-en-em[2]), represented by the chemical symbol or formula Pt[1], is a soft, heavy, malleable, ductile and extremely rare element belonging to the family of transition metals[3, 11].Naturally occurring Pt is a mixture of 6 isotopes with...
Properties and Uses of Thermistors--- Thermally Sensitive Resistors A new circuit element and control device, the thermistor, or thermally sensitive resistor, is made of solid semiconducting materials whose resistance decre...

Properties of intruder bands in the Os-Pt-Hg-Pb region Band mixing is used to reproduce the collective bands associated with shape coexistence in even-even osmium, platinum, mercury, and lead nuclei. The proper... G.,D.,Dracoulis - 《Physical Review C》 ...
magnetron sputtering on silicon and platinum-coated silicon substrates with different buffer and barrier layers. Electrical properties of BST films have been evaluated using both metal–insulator–semiconductor (MIS) and metal–insulator–metal (MIM) structures. MIS capacitor C–V and G–V ...

lanthanides, and not the actinides, are classified as rare earths. The lanthanides are not as rare as was once thought; even the scarce rare earths (e.g., europium, lutetium) are more common than the platinum-group metals. Several of the lanthanides form during the fission of uranium and...
