Osmium and Iridium: An in-depth comparison from physical properties to applications

Osmium and iridium, as two members of the platinum group metals, although their chemical properties are similar, there are significant differences in physical properties, application fields and refining processes. This article will explore these differences in detail and gain insight into the recycling process of iridium osmium waste.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Physical property文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Osmium: The densest known element, osmium has a density of 22.59g/cm³. It is a hard metal with high tensile strength and hardness. Because of this property, osmium is often used in the manufacture of high-hardness alloys and tool steels.
Iridium: Iridium is the second densest of all elements, after osmium. Its density is as high as 22.56g/cm³. Iridium is also extremely hard and has excellent wear and corrosion resistance. This metal has a very high melting point of 2454 ° C. Therefore, iridium can maintain excellent mechanical properties at high temperatures.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Chemical property文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Osmium: In chemical reactions, osmium is more active. It easily forms stable osmic acid and osmate. In oxidizing environments, osmium tends to form stable oxides of osmium (IV) and osmium (VI).
Iridium: The chemical properties of iridium are relatively stable compared to osmium. Iridium is not easily oxidized at room temperature and pressure. Iridium oxidizes relatively slowly, even at high temperatures. This makes iridium exhibit excellent corrosion resistance in many industrial applications.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Due to their unique physical and chemical properties, osmium and iridium are widely used in various industrial fields.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Osmium: mainly used in the manufacture of pen tip materials, high-strength alloys and some special alloys. Due to its high density and hardness, osmium is also used to make high-hardness tools and cutting tools.
Iridium: Iridium has a wider range of applications. In addition to its applications in pen tip manufacturing and high-strength alloys, iridium is widely used in superalloys, electrical contact materials, hard alloys, and catalysts and electrode materials in the electronic and chemical industries due to its excellent corrosion resistance and high temperature stability.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Iridium osmium waste recycling case文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Date: February 2023
Location: Tokyo, Japan
Source of waste: Waste catalyst from a chemical plant
Recycling process:文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Collection and classification: Waste catalysts are collected from the plant and sorted according to iridium and osmium content.
Physical treatment: The catalyst is broken to the appropriate particle size by grinding, crushing and other physical methods for subsequent chemical treatment.
Chemical dissolution: Use strong acids (such as aqua regia) to dissolve iridium and osmium. The purpose of this step is to separate iridium and osmium from other insoluble substances.
Metal extraction: By electrolytic deposition or other chemical precipitation methods, the dissolved iridium and osmium are extracted separately. The goal of this step is to achieve a high purity separation of iridium and osmium.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html

Purification treatment: After several purification treatment, to ensure that the purity of the obtained iridium and osmium meet industrial standards.
Recovery assessment: Economic assessment of the entire recovery process based on market prices and recovery costs.
Environmental treatment: The waste acid and other waste generated are properly disposed of to ensure that the entire recycling process meets environmental requirements.
Through this case, we can see the specific operational processes and challenges of recovering iridium and osmium from waste catalysts. As technology continues to advance, these recycling methods will become more efficient, environmentally friendly and economical, making an important contribution to the sustainable use of resources.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47345.html
