Rhodium Lump

Product Overview

Rhodium lump is a silver-white, hard metal block belonging to the platinum group, known for its high reflectivity. Rhodium typically does not form oxides; molten rhodium releases absorbed oxygen during solidification. It has a higher melting point than platinum but a lower density and is insoluble in most acids, especially completely insoluble in nitric acid, but slightly soluble in aqua regia.

Key Features

• High Reflectivity:Rhodium lumps exhibit excellent reflective properties, making them suitable for optical and industrial applications.
• Strong Wear Resistance:The hardness of rhodium allows it to perform exceptionally well in high-wear environments.
• High Melting Point and Corrosion Resistance:Rhodium's high melting point and oxidation resistance ensure its stability under extreme conditions.
• Modification Capability:Rhodium can form solid solutions with other metals, improving the melting point, recrystallization temperature, and corrosion resistance of materials.

Applications

• Catalysts:Rhodium lumps and their alloys are used in the synthesis of aldehydes, automotive exhaust purification, and the synthesis of plastics and pharmaceuticals.
• Optical Coatings:Due to its high reflectivity, rhodium is often used for coatings on specialized industrial mirrors and reflectors.
• Corrosion-Resistant Containers:Suitable for manufacturing containers that can be used in high-temperature and corrosive environments.
• Electrical Contact Materials:The wear resistance and stability of rhodium coatings make them excellent electrical contact materials, widely used in electronic devices.
• Alloy Manufacturing:Forms solid solutions with metals like platinum and palladium to enhance material performance; rhodium-platinum alloys are commonly used in high-precision temperature measurement materials.
