Product Overview
Osmium Pellets are made from high-purity osmium metal, known for its extremely high density and melting point. These pellets are widely used in the manufacture of catalysts and alloys. Osmium has a gray-blue color, is hard and brittle, and is highly stable in air. The high density of osmium gives it great value in various industrial and scientific applications, particularly in the production of catalysts, alloys, and key components for high-precision instruments.
Product Features
- High Density:Osmium is the densest known metal, with a density of 22.48 g/cm³.
- High Melting and Boiling Points:The melting point reaches 3045°C, and the boiling point exceeds 5027°C.
- High-Temperature Resistance and Stability:Osmium is stable in air, but its powdered form is prone to oxidation.
- Hardness and Brittleness:Osmium is highly hard but brittle, making it prone to pulverization.
- Toxicity:Osmium vapors are highly toxic and can severely irritate the eyes, potentially causing blindness; handling requires extra safety precautions.
Applications
- Catalysts:Osmium is used as a catalyst in ammonia synthesis and organic hydrogenation reactions.
- Alloy Manufacturing:Osmium is used to create corrosion- and wear-resistant iridium-osmium alloys, which are widely applied in electrical contacts, instrument pivots, and more.
- Spectral Analysis:Osmium pellets are utilized as essential materials in spectral analysis.
- High-Precision Instruments:Osmium is used in the production of machine bearings, phonograph needles, pen tips, and other high-precision components.
