Product Overview

Hafnium lump is a silver-gray transition metal with high density and excellent high-temperature performance. It remains chemically stable at room temperature, though its powder form is highly reactive and can self-ignite in air. At elevated temperatures, hafnium exhibits low chemical reactivity and can form a protective oxide layer, providing excellent corrosion and oxidation resistance. With its high melting and boiling points, hafnium shows exceptional heat resistance under extreme conditions. It is primarily used in nuclear materials, alloys, and high-temperature applications.

Features

High Density and Exceptional Heat Resistance:Ideal for extreme temperature environments.
Good Corrosion and Oxidation Resistance:Durable in harsh conditions.
Strong Stability:Suitable for use in extreme environments.
Easy to Process and Customize:Meets various specification requirements.

Applications

Nuclear Industry:Due to its large neutron absorption cross-section, hafnium is used in nuclear reactors as control rods and shielding devices.
Alloy Manufacturing:Hafnium is commonly used as an additive in high-temperature alloys, such as tungsten and molybdenum alloys, enhancing their strength and heat resistance.
High-Temperature Materials:With its high melting point, hafnium is used in aerospace applications for high-temperature materials, such as rocket nozzles and injectors.
Electronic Materials:Hafnium is utilized in electronic devices, especially for high-temperature and high-pressure applications, such as electron tubes and electrode materials.
Corrosion-Resistant Materials:Used in industrial equipment and chemical containers that require long-term high-temperature and corrosion resistance.
Optical and Catalysis Applications:Hafnium is used as a catalyst or alloying element in optical coatings and catalytic reactions.
