Nano Hafnium Powder: Core Fundamental Material
Nano hafnium powder refers to hafnium metal powder with particle sizes in the nanometer range (typically 10–100 nm). Compared with conventional hafnium powder, nano hafnium powder offers more prominent advantages due to its large specific surface area, high reactivity, high melting point (~2227°C), and high density (13.3 g/cm³).
Product Features
High melting point & heat resistance: Suitable for use in extreme high-temperature environments.
Excellent neutron absorption: Hafnium is a key control material in nuclear reactors.
High chemical stability: Provides outstanding corrosion resistance under most conditions.
High surface activity: Nano-scale particles easily bond or react with other materials, facilitating the preparation of composite materials.
Application Fields
Nuclear industry: Reactor control rods, neutron-absorbing components
Aerospace: Additives for high-temperature alloys, enhancing heat resistance and corrosion resistance
Semiconductors & energy: Catalyst carriers and advanced electronic materials
Storage & Safety
Due to its high reactivity, nano hafnium powder should be handled and stored with care:
Keep sealed in a dry, cool environment; avoid exposure to air to prevent moisture absorption, oxidation, or agglomeration, which may affect dispersion and performance.
Recommended storage under inert gas or in vacuum conditions.
Wear protective equipment during handling to prevent inhalation or direct skin contact with nanoparticles.
Packaging can be customized and supplied in quantities according to customer requirements.
As a trusted nano hafnium powder supplier, we provide products with purity ≥99.9%, and can customize particle size specifications according to application needs, ensuring stable material performance and reliable supply.
