Rhodium metal is a rare and precious platinum group metal, which has a wide range of applications in industry due to its excellent physical and chemical properties, especially in automotive exhaust catalytic converters. However, rhodium metal resources are very limited and the cost of mining is high, resulting in a high market. Therefore, the utilization of rhodium metal has become an effective way to save resources and reduce costs. This article will introduce the best situation of rhodium metal from the following aspects.
First of all, the *** of rhodium metal is affected by a variety of factors, usually between 200 and 800 yuan per gram. This ** will fluctuate with changes in market supply and demand, purity, and rhodium form and content. The ** value of rhodium is closely related to the purity of rhodium itself, and the higher the purity, the higher its *** will also increase. In addition, the form and content of rhodium will also affect its *** For example, different forms such as rhodium powder, rhodium flakes, rhodium wire, etc., as well as the alloy ratio of rhodium to other metals, will have an impact on the rhodium alloy.
Secondly, the demand for rhodium metal is very large, mainly from the automobile, petroleum, chemical, glass, medical and other industries. Among them, the automotive industry is the main area of rhodium metal**, because automotive exhaust catalytic converters contain a large amount of rhodium, and these catalytic converters will fail or be damaged after a period of use, and need to be replaced or repaired. At this time, the discarded catalytic converter can be dismantled and **, and rhodium can be extracted from it. According to statistics, about 3,000 tons of rhodium are released from automobile exhaust catalytic converters every year. In addition to the automotive industry, the petroleum, chemical, glass, medical and other industries will also use rhodium as catalysts, coatings, electrodes, etc., and these rhodium can also be used after use.
Finally, the technology of rhodium metal continues to develop, improving efficiency and quality. The most advanced technology of rhodium metal mainly includes physical method, chemical method and biological method. The physical method is to use the physical properties of rhodium, such as density, magnetism, conductivity, etc., to separate and purify rhodium. The chemical method uses the chemical properties of rhodium, such as redox, complexation, precipitation, etc., to separate and purify rhodium. The biological method uses the metabolism of microorganisms to isolate and purify rhodium. These technologies have their own advantages and disadvantages, and it is necessary to choose the right technology according to different objects and conditions. With the progress of science and technology, the high-quality technology of rhodium metal is also constantly improving and innovating, improving the efficiency and quality, reducing the cost and environmental pollution.
