The meaning of OSMIUM is a blue-gray or blue-black hard brittle very heavy polyvalent metallic element with a high melting point that is used especially as a catalyst and in hard alloys.
He announced its isolation (1804) and named it for the unpleasant odour of some of its compounds (Greek osme, odour). Of the platinum metals, osmium is the most rapidly attacked by air. The powdered metal, even at room temperature, exudes the characteristic odour of the poisonous volatile ...
What is Osmium Used for Addition of the metal to alloys increases hardness making them useful in the manufacture of ballpoint and fountain pens, jewelry like rings, electrical contacts, record player needles, instrument pivots, and other devices prone to frequent wear and tear[1, 2]. ...
Because of the volatility and extreme toxicity of its oxide, osmium is rarely used in its pure state, but is instead often alloyed with other metals for high-wear applications. Osmium alloys such as osmiridium are very hard and, along with other platinum-group metals, are used in the tips ...
autosomal dominant form except for the markedly elevated acid phosphatase levels. Bollerslev has provided a detailed study of several biochemical variables in two variants of the autosomal dominant condition (33). Acid phosphatase was increased markedly in what he refers to as type II; type I was ...
Osmium is not affected by the common acids, and is not dissolved by aqua regia. It is practically unworkable, and its chief use is as a catalyst. Osmium tetraoxide, a commercially available yellow solid (melting point 40 C) is used commercially as a stain for tissue in microscopy. It is...
The atomic number of osmium is the number of protons present in the nucleus of an atom of a chemical element. In the case of osmium, this number is 197. However, atomic numbers assigned to elements ar.. What are the common uses of osmium?Many people are curious about osmium and its ...
