Human discovered the treasures of the earth and content of metals of value, and the work on the extraction and use in the tools industry, then the evolution of use for these metals with
Radium chemical element in the periodic table, and his character Rh, atomic number 45. It is a rare transition metal solid. One of the platinum group. And exist in nature mixed with platinum ore. It is the most expensive precious metals at all and the reason Glaih due to the increased cost of extraction process, where the extraction process must be done through the purification precious metal platinum price and the difficulty of separation of known compounds that combine with Kalrodiom.
Frenchmen discovered by physicists Pierre and Marie Curie and Msaadahma Gustav Beaumont in 1898 during their experiences on metal Alaoraninayat (Alapthiblnd). A mineral containing uranium ore.
The cost per gram is about $ 300, this metal makes strange soft materials harsh. This property is exploited Weber gas industry hardener for their products. Radium is used widely in car exhaust industry, where radium in Ketelizatr able to convert harmful gases into harmless gases such as nitrogen and carbon dioxide.
* Supernova: is a type of supernovae and expression shows several massive stellar explosions which aims its cover star in space at the end of its life. Lead to the formation of spherical cloud around the star very glamorous (severe sparkles) of plasma.
* Mohs scale: Scale is used to denote the ability of different materials to resist scratching any amount Slaptha.oeetm by examining the ability of a solid material to scratch material hardness less of them.
A metal rare silvery-white, and excellent corrosion-resistant and reflective dramatically. It uses pure rhodium factory owners in the latter stages of the lights and floodlights jewelry industry. It is also used in electrical connections, and cursing with platinum for the manufacture of turbine engines for aircraft. And help such alloys as a catalyst in some industrial processes, such as nitric acid industry and some hydrogenation of organic compounds. ± 100 ° m and density of 12.41 g / cm² at 20 ° C. Separation of material rhodium, English chemist William H. Wollaston, in 1803.
A mineral discovered by William Hyde Wollaston in 1803, and is one of the precious metal expensive, because of the high extraction costs, rhodium and is characterized as metal non-corrosive, good conductivity of electricity, enters in the jewelry industry, is also included in the platinum for the manufacture of turbine aircraft engines industry
Radium only in the chemical industry, and all metal rhodium compounds used cause poisoning and cancer. They also leave marks of the strong spots on the skin. There are no any results indicate the occurrence of food poisoning because the rhodium concentrations slim
scientific progress day after day, has markets accounted for most of these minerals psychological expensive balance of the global economy, since the physical value affect large commercial and physical exchange of countries and each other, and were the basis for calculating the value of international currencies, has also been used many of them in the currency industry, and ornaments, and entered into a medical and therapeutic industries, and today we know the best of those precious metals on the surface of the earth.
