Osmium

A chemical element with the symbol Os and atomic number 76

Osmium is a rare, dense (22.59 g/cm^3), and extremely hard metallic element that belongs to the platinum group of metals. It is one of the least abundant elements on Earth and is highly valued for its unique properties. Here’s a breakdown of Osmium’s properties:

1. Rarity: Osmium is one of the rarest elements on Earth and is found in very small quantities. It is typically found in the Earth’s crust and in mineral deposits alongside other precious metals.
2. Durability: Osmium is an extremely hard and durable metal, with a high resistance to wear and tear. It is also highly resistant to corrosion, making it a popular choice in many industrial applications.
3. Malleability: Osmium is not very malleable or ductile, meaning it cannot be easily shaped or formed like other precious metals.
4. Conductivity: Osmium is a good conductor of electricity and heat, making it useful in various industrial applications such as electrical contacts, spark plugs, and other high-temperature components.
5. Beauty: Osmium has a unique silvery-blue color and a high luster, making it a popular choice in jewelry and decorative items.

Osmium is primarily used in industrial applications such as the production of electrical components, fountain pen tips, and instrument pivots due to its high durability and resistance to corrosion. It is also used in the production of specialized alloys, including those used in the manufacturing of military-grade hardware and surgical implants.

Osmium is mainly found in Russia, Canada, and South Africa, with smaller deposits found in other countries such as the United States and Colombia. Osmium is found in nature as an uncombined element or in natural alloys; especially the iridium–osmium alloys .Osmium is 1,500 times more rare than gold but only 30 times more expensive. The price at the beginning of 2023 was 1800$/gram (gold was only 60$/gram).

Overall, osmium is a rare, shiny and valuable metal that is primarily used in industrial applications due to its unique properties. It is found in limited quantities and is highly

sought after by various industries that require its high durability and resistance to corrosion.

Osmium Market and Demand (2019–2025)

Unlike platinum, palladium, or rhodium, osmium remains one of the smallest and least liquid precious metals markets. Due to limited industrial applications and the absence of transparent exchange trading, prices are typically established through direct transactions between market participants. After remaining

relatively stable around $250/oz between 2019 and 2021, indicative osmium sponge prices increased steadily, reaching approximately $400–450/oz in 2025. Demand is estimated at only a few tonnes per year, with roughly two-thirds consumed in specialized industrial applications such as electron microscopy and osmium-based chemical processes. Additional demand comes from scientific collectors, hobby metallurgists, and a niche jewelry and investment market. While emerging applications may support future growth, osmium’s unique chemistry, limited supply, and specialized end uses are expected to keep the market relatively small compared with other platinum group metals.
