Ruthenium
Ruthenium (Ru) is a rare, hard, and brittle transition metal belonging to the platinum group. It is highly resistant to corrosion, especially in air and acids, and often serves as an alloying agent to improve the hardness and durability of other metals. With a high melting point of 2334 °C and stable chemical properties, Ruthenium is ideal for demanding scientific and industrial applications.
Goodfellow’s premium range of Ruthenium products, including Ruthenium Rods, Sputtering Targets, Pellets, and Foils, plays a critical role in advanced research and industrial applications. Ruthenium’s unique properties make it highly useful in fields like electrochemistry, semiconductor manufacturing, and materials science. Ruthenium-based materials are extensively used in fuel cells, chemical sensors, and electronics. With a focus on high purity and precision, our Ruthenium products support cutting-edge advancements in catalytic processes, thin-film technology, and advanced coatings, making them essential for researchers and industry professionals driving innovation.
