Pure Platinum has a melting point of 3224 degrees F. / 1773 degrees C., the specific gravity is 21.45 g/cu cm @ 20 degrees C. Over the past 5 years the popularity of jewelry made of Platinum alloys has increased dramatically and many jewelry manufacturers are … Sponsored Links . Platinum is used in catalytic converters, laboratory equipment, electrical contacts and electrodes, platinum resistance thermometers, dentistry equipment, and jewelry. Comparing with market messy circuit design, SperbMelt adopts advanced micro computer controlled power save over 30% consumption. SuperbMelt platinum melting furnace is designed to melt 1-4kg platinum, gold, palladium, speedy melting within 3 min and max temperature of 2600℃. The softening point of fused silica proved to be too near the melting point of platinum to avoid serious distortion, and another solution of the problem had to be sought. Platinum Melting Furnace, Gold/Silver/Platinum Induction Smelter. It has a coefficient of thermal expansion close to that of soda lime silica glass and is consequently used to make sealed electrodes in soft glass systems. Some fifty years ago Donald McDonald wrote in Platinum Metals Review on ‘The History of the Melting of Platinum’ (1) and Leslie B. Note that, these points are associated with the standard atmospheric pressure . Physical properties of Platinum include melting point, boiling point, mechanical strength Both platinum and palladium are often used as catalysts, meaning they speed up chemical reactions without themselves being chemically altered in the process. Melting point of Platinum is 1772°C. - search is the most efficient way to navigate the Engineering ToolBox! Platinum definition, a heavy, grayish-white, highly malleable and ductile metallic element, resistant to most chemicals, practically unoxidizable except in the presence of bases, and fusible only at extremely high temperatures: used for making chemical and scientific apparatus, as a catalyst in the oxidation of ammonia to nitric acid, and in jewelry. Presented November 13, 1895. Boiling point of Platinum is 3827°C . Metals and Alloys - Melting Temperatures Melting temperatures of common metals and alloys . Platinum has broad chemical resistance although the metal may be dissolved in aqua regia, a highly acidic mixture of nitric and hydrochloric acids, forming chloroplatinic acid, and has an extremely high melting point in excess of two thousand degrees centigrade. The melting point of a substance depends on pressure and is usually specified at standard pressure. By S. W. Holm an, with R. R. Lawrence and L. Barr. Platinum is an attractive silvery white metal with a melting point of 1,774 deg C, a boiling point of 3,827 deg C and a density of 21.45 g/cu cm at room temperature.
