This article discusses how he and some of his predecessors accommodated the platinum group metals (pgms) in the Periodic Table, and it considers the placing of their three transuranic congeners: hassium (108Hs), meitnerium (109Mt) and darmstadtium (110Ds). Over twenty-five years ago McDonald...
The platinum group metals are among the rarest and most precious metals known. The word platinum comes from the Spanishplatinameaning “little silver”. This name was first used in thesilvermines of Colombia where miners came across the metal and considered it a worthless impurity of silver. In...
Ruthenium, rhodium, palladium, osmium, iridium, and platinum together make up a group of elements referred to as the platinum group metals (PGM). Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile. It has a coefficient of expansion almost equal to that of ...
Compounds of metals from the platinum group of the periodic table compounds are encapsulated within a thermoplastic organic polymer using known prior art techniques. The presence of trace amounts of the encapsulated compound on the surface of the microcapsules is avoided by preparing the microcapsules ...
the platinum-group metals, the concentration of PGE collected by chromite increased with time. The primary PGMs thus precipitated could have been subsequently modified by low-temperaturehydrothermal alterationand metasomatic addition of metals like Cu, Fe, and Ni....
platinum group, six metals, in order of increasing atomic weight, ruthenium (Ru), rhodium (Rh), palladium (Pd), osmium (Os), iridium (Ir), and platinum (Pt). The elements all possess a silvery white colour—except osmium, which is bluish white. The chemical behaviour of these metals ...
As this paper has a focus on the platinum group metals, the examples of various catalytic processes only refer to those processes where a PGM is used. Table 5 summarises many of the homogeneous and heterogeneous catalytic reactions where PGMs are the active catalytic component. Heterogeneous ...
Petersburg University, 7/9 Universitetskaya Nab., Saint Petersburg 199034, Russia Deadline for manuscript submissions: closed (31 March 2024) Message from the Guest Editors Dear Colleagues, Recently, luminescent complexes of platinum group metals have attracted much attention because of their intriguing...
DOWEX™ Anion Exchange Resins have proven to be tough, steady performers in the separation of Platinum Group Metals (PGM) from liquid media.
Platinum is a transition metal in Group 10 (VIIIB) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Platinum is also a member of a group of metals named after itself. Other platinum metals include ruthenium, rhodium, palladium...
