In the literature the accepted melting point of osmium metal is reported as 2750°C. It has now been established that this value is low and a redetermination gives 3045 ± 30° C.doi:10.1016/0022-5088(60)90044-8A.G. KnaptonJ. Savill...
Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). They have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. More than half the supply of palladium and ...
Because the segments possess different physical properties, such as glass transition temperature (Tg), crystalline melting point (Tm), dielectric constant or solubility parameter the resulting polymers possess enhanced properties. For example, the presence of crystalline polymer segments having a relatively ...
A discontinuity in the seismic velocity associated with the lithosphere-asthenosphere interface, known as the Gutenberg discontinuity, is enigmatic in its origin. While partial mantle melts are frequently suggested to explain this discontinuity, it is no

Indeed, some of them, such as tungsten, molybdenum, and all of the platinum group of metals, except osmium, are secondary fixed points on the International Temperature Scale of 1990 (ITS-90) ().Black Pig Ltd, The Sty, Upper King St, Royston, SG AZ...
A method to estimate the melting point of pure osmium is discussed. In order to properly assess periodic trends it would be useful to have an accurate determination of the melting point carried out on high purity metal and using modern equipment in an oxid...
Taking into account the large volume of new data, the calculation of the melting curve of osmium, together with determination of its heat of fusion, has been revised. The new results agree noticeably better with quantum mechanical calculation data. It is significant that the sl...
